Without problems and directly at connecting a device. How? With a new Euroclamp MPF03 terminal block with integrated fuse holder.

Nowadays, when “almost everything” works on electricity we can see still more devices connected to mains line. That´s why it often happens, that many small-power devices are connected to one (circuit breaker fused) line. To increase a safety, it´s usually advantageous to fuse particular devices separately – for example by small glass fuses. Somewhere it´s advantageous on a panel or directly on a PCB, elsewhere directly in a control relay interface module and in many cases directly in a place of connection.

For this purpose a novelty in our offer is very suitable – 3-pole terminal block MPF03-10, where one of poles is fused by a glass tube fuse 5x20mm. In praxis it can look so, that on a place where you so far used a classic (“chocolate”) terminal block, you can use MPF03 and insert a suitable fuse.

In the MPF series can be found series with 1-5 poles. As already a name says, pin spacing (pitch) of the MPF series is 10mm. On stock we have the 3-pole version MPF03-10 ideally suitable for mains line appliances (L,N,PE). Exact dimensions and further parameters can be found in the Euroclamp MPF03-10 datasheet.

In our portfolio can be found quality knobs from company Cliff suitable for a wide range of potentiometers and encoders.

A device with excellent specification, quality components used, …., but a one step is still missing to reach a great overall impression – it is to use a quality and aesthetic control components.

Probably you´ll agree, that knobs for potentiometers and encoders belong to a “group of critical components”, determining a resulting look of a device. Company Cliff specializes on development and production of these components already from 1977 and considerable experience are reflected in a precise construction and a wide portfolio of components produced.

Directly from our stock, we´re able to offer you a few interesting series:

  • K87MAR – plastic two-color knob with a colored top part and a side line. Available in 8 standard color versions. Thanks to a big popularity and a mass production, their price is very affordable. User friendly, soft – “rubber-feel” surface. Excellent for color coding of potentiometers groups in equipment with many knobs. 6mm „D“ shaft.
  • K87MBR – plastic two-color knob, very similar to series K87MAR, but only a side line is in color. Affordable price and a mild “rubber-feel” surface. 6mm splined shaft or 6 mm “D” shaft.
  • K18 – universal plastic knob for electronic encoders. Available in 5 colors and 3 weight categories. In our stock can be found 2 heavier versions (35 and 50g) in a grey and black color.
  • KMK – universal aluminium knob with a machined aluminium shell and a molded plastic inner. Available in a black or natural anodized surface. Push-on installation. In our stock can be found 4 versions with a 25 mm diameter – KMK25 in a black and silver (natural) color, with a 6mm splined as well as “D” shaft.

Types for splined arbors have 3 relatively robust juts (as visible on a Picture), that´s why they´re suitable only for potentiometers with deeper splines, or with a lower splin count. From our offer they´re suitable for example for Taiwan-Alpha potentiometers and they´re not suitable for potentiometers Piher series PC16.

Further information will provide you the K87MAR, K87MBR, K18 and KMK datasheets. Upon request, we´re able to deliver you more types from the portfolio of Cliff knobs.

Maybe it´s the right time for you to also consider usage of OLED displays in your applications.

The most advanced display technology – OLED, goes ahead into many industrial products thanks to its advantages. From a certain point of view exactly the industrial environment properly checks features of displays and especially in critical applications extreme thermal resistance a big advantage (immediate response even in frost).

As it uses to be, new technologies are rarely cheap. In case of OLED we can say about significantly more affordable price than a few years ago. For example even despite currently disadvantageous EUR/USD exchange rate, when many components become more expensive, renowned OLED character displays from company Electronic Assembly became cheaper during last weeks.

Naturally even LCD displays still have their undisputed advantages, for example a very low power consumption (EADOG series) and depending on type also a legibility even without a backlight. However in applications where you consider OLED vs. LCD (with a backlight), in majority of cases an OLED is a better choice. OLED is a better choice mainly because of unbelievably wide viewing angle, immediate response and a great contrast, where a black is truly black.

In our offer we have character OLED displays EAW series but also other universally usable OLED displays.
Some types of the EAW series are available in 2 versions – yellow/green and ice white. Detailed information will provide you the EAW flyer and the EAW datasheet.

Audible click, protection against backing out and disengagement together with many versions and attractive price – these are the Power Tripple Lock connectors.

Universal connectors for interconnection of leads (wire-to-wire) as well as leads to a PCB (wire-to-board) are necessary every day and practically everywhere. In industrial applications we usually need various connectors. “Various” usually means almost uncountable amount of types, that´s why it´s usually a big advantage if it´s possible the same connector for several applications. This “versatility” is considerably met by a new series of connectors Power Tripple Lock. Commercial products, industry, transportation – all these segments are addressed by Power Tripple Lock from company TE Connectivity.What does the „Tripple Lock“ mean?
As already the name says, it is a triple locking – protection against disconnection. The basic and the most important is a sophisticated design with exactly mating parts and a reliable lock. Audible click is a discreet but very useful feature contributing to a correct connector assembly.

Optional protections are „CPA“ and „TPA“

  • CPA (connector position assurance) is an optional plastic part – additional lock against mistaken disengagement.
  • TPA (terminal position assurence) is an optional plastic part used from the rear connector side (from leads) ensuring a 100% exact leads, helps precise mating and improves overall reliability and immunity to vibrations and stresses.

Connectors are available with pins in a single row (2,3,4,5), two rows (2×3,2×4,2×5,2×6) and in a matrix (3×3,3×4,3×5) with 6mm pin spacing. Basic parameters are 20A/600VAC or DC. Also interesting is the fact, that connectors are available in three material versions with a different thermal resistance (all are UL 94V-0):

  • PBT standard (-55…105°C)
  • high temperature (-55…150°C)
  • „Glow wire“ (750°C no flame) according to IEC 60335-1

Prevention against improper connectors assembly is a different colour coding of particular material versions. Another factor preventing improper connection are 4 possibilities of keying (necessary if the same connectors are in one device). Power Tripple Lock is a big family of connectors containing connectors “wire-to-wire“ (free hanging leads),“wire-to-board“ as well as panel mount versions.

Versatility of Power Tripple Lock connectors is also underlined by a wide range of usable wires cross sections in a range of 0,34-3,3mm2 (12-22 AWG). A comprehensive overview of Power Tripple Lock connectors can be found in the „Improving appliance connector designs“ flyer and in the „Quick Reference Guide“.

A possibility to read an RFID card even on a longer distance is usually highly appreciated at its everyday usage.

As we know, RFID module range is expressively depending on a size and shape of the RFID antenna (coil). That´s why the module with a big antenna has a potentially bigger chance to reach a long range. This is exactly a case of the ID3LA module – working in a wider operating voltages range (2,8-5V) than its predecessor – the ID2 module. This enables its usage even with a 3.3V logic and also for example in battery-operated devices (3-4x NiMH, or 1x Lithium cell, …) not requiring DC converters or a precise voltage regulation.

ID3LA belongs to the „ID3/ID12/ID20“ family with very similar electrical parameters and a way of usage. All modules of this family function as readers sending data – a unique ID of a given RFID tag. The most favourite type – ID12(LA) has a very decent range (approx.. 12cm) sufficient for majority of applications. However, if the space in your application allows you to use ID3LA, you´ll reach a significantly longer range. ID3LA requires an external antenna – included in the package, as illustrated on the attached pictures.

Detailed information will provide you the ID3LA datasheet.


With the ID3LA RFID module it´s possible to read a tag up to 30cm – [Link]

If a production of a professional bezel is over above your possibilities, leave it to us.

Also can be added, that even in case you have a possibility to produce a suitable bezel, it can easily happen (especially at smaller batches) that it simply isn´t worth it. Design, prototyping,… all this costs something. On the other hand we have here a ready-made solution with true brass bushings and precisely designed spring clips. The result is an immediately usable bezel, while it´s only necessary to make a simple cut-out into the front panel of the device. There´s no need to drill mounting hols to exactly defined positions or so. We talk about 4D Bezel-s. Novelty in our stock offer are bezels for 7“ displays uLCD70. Bezels are available in a black and white version. In our standard offer can also be found bezels for 3,2“ and 4,3“ displays from company 4D Systems.Further details necessary for a trouble-free usage in a target device will provide you the 4D-Bezel-70 datasheet as well as other ones at particular types.

Favourite series 1553 hand-held enclosures are now available even in a water-resistant version with IP65 rating.

Ergonomic enclosures of the 1553 series with a non-slipping surface found their place on a market very quickly. Precise construction with brass bushings, stainless steel screws included, easy PCB placing on standoffs and other details make this series of enclosures universal for practically any “mobile” applications.

Despite very well fitting parts of an enclosure minimizing a possibility of a dust ingress into enclosure, there certainly are applications with a higher risk of water and dust penetration. For these cases the new “W” version is suitable, i.e. 1553W with integrated sealing and a whole construction designed so as to meet IP65 requirements. Fixing positions for screws are located outside the gasket ensuring sealing integrity.

Hammond 1553W series is available in “B”, “C” and “D” sizes, i.e. 1553WB (117x79x25mm), 1553WC (117x79x32mm) and 1553WD (147x90x25mm). All sizes are further available in two colours – whit-grey and black (GY/BK). Further details can be found in datasheets at particular types below this article.

New series of Friwo FOX mains adapters meets the most stringent energy regulations already now and at the same time it´s more compact than its predecessors.

DoE 2016 is a known term naming stringent regulations established by DoE (department of energy USA) valid from year 2016. Among other things it brings a requirement for a standby power consumption of small adapters to be below 0.1W. In Europe we have here a limit of 0.5W for majority of small adapters, but even here can be expected toughening in the nearest years.

That´s why German company Friwo as a long-term long-term OEM producer of power supplies and adapters comes with a new line of mains adapters named “FOX”. Besides high efficiency, these power supplies are also extraordinarily compact. Already recent series MPP and GPP are very compact, but FOX is a “step further”, as also illustrated on attached picture. System of exchangeable primary and secondary adapters (connectors) enables to use the same power supply for various applications and in various countries.

Even the FOX series meets various international requirements and obtained many approvals. a medical version will be also available soon. The FOX series is a novelty – 12W types are available upon order. Gradually also other types – FOX 18, FOX 30 a FOX 6 will be produced.
FOX series, as the only type on the market that meets criteria for IP42 protection – with selected primary adapters (connectors).
The first type from the FOX series – FOX 12 Office 5V/2200mA (1896623) with the 5V output voltage can be already found in our standard stock offer. As the power supply is designed as “modular”, it´s necessary to also buy appropriate primary and secondary adapter (connector) and the output cable, i.e. for example FOX Adapter/EURO (1844847) , COAXCON5.5/2.1/9.5 (1807700) and FOX Distribution DC-Cord.

Desoldering braid makes an invaluable service at development or rework.

Everyone who´s ever tried to suck off a solder from a solder pad by means of a solder absorbing braid (wick) will probably confirm, that this tool belongs to a “must have” equipment of every professional or amateur workplace. What´s the charm of a desoldering braid? Above all in the fact, that it´s able to absorb almost all the solder from a given place, thus the most of components can be loosened very easily. Hand (pneumatic) pump surely has its place, mainly when working with bigger components, but at comparison with a desoldering braid it´s similar like if we compared a broom with a vacuum cleaner.

A quality desoldering braid is usually able to absorb a solder so thoroughly, that only a microscopic layer of a solder will remain on a PCB – as if a board was new, unused. It is very advantageous even at a hand rework of SMT components, because it´s desirable the component to lay directly on a board – not askew in a thick solder layer causing a mechanical tension and able to cause even a malfunction of a component (often at SMT capacitors).

To reach a good functionality of a desoldering wick it should be made of a fine gauge copper wires (without oil residues end similar) and it must be treated with a high quality flux. The cheapest braids usually contain only a rosin-based flux, the better ones have a synthetic flux based, which produce less fumes.

A novelty in our portfolio is the novelty from company CRC Industries – braid SOLDABSORB. We keep Soldabsorb in a width of 1.5 and 2.5mm, packed in a blister in 2 pcs (the price is for 2 pcs). Soldabsorb represents a top-level in this segment and is made of a highly pure copper, fine gauge wires and contains a synthetic NO-CLEAN flux. It means, that the flux residues are non-conductive and non-corrosive and they can be left on a PCB. Very fine wires contribute to a high wicking (absorbing) ability.

The usage of the wick is very simple and is based in 4 steps:

  • Place the Soldabsorb wick on the solder joint
  • place the tip of the solder iron on the wick and hold shortly
  • absorbed solder will change a color of a braid, showing that the process was successful
  • when a joint contains a big amount of solder, it may be necessary to cut off a used end of a braid (2-5mm) and repeat the process

In praxis it approves well to adjust temperature of a soldering iron to a slightly higher, than we´d normally need for a given pad and eventually also to use a thicker soldering tip. In especially difficult cases (vias at ground planes of a PCB) it helps to put a small amount of a new solder on a soldering tip, which will decrease an absorbing ability of a braid, it will significantly improve a heat transfer from a tip through a braid to a PCB, thus improving and speeding up an absorption. Before another use of a braid, it´s sufficient to cut off only a very end of a braid (a few mm) fully sucked by a solder.
At the end it´s worth to mention, that after desoldering, it´s good to apply a small amount of solder on a soldering tip to protect it from oxidizing.

Detailed information will provide you the Soldabsorb datasheet.
