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“.

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.

GW134T_Frontby elektormagazine.com:

CAP-XX have introduced a range of flat single-cell supercapacitors targeted at small (or disposable) devices for IoT applications. This new Thinline range boasts the world’s thinnest supercap at 0.6 mm thick. CAP-XX use a unique nanotechnology construction that stores electrical charge in engineered carbon electrodes on aluminium foil to minimize resistance and maximize capacitance. This type of electrode construction packs the highest energy and power densities possible into thin, prismatic packages.

The idea was born while working with a customer designing a disposable insulin pump. “We figured out how to eliminate materials and change some processes to reduce costs and thickness,” explained Anthony Kongats, CAP-XX CEO.

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.

Power supplying, control, but also signal transmission from various sensors can be confided to ST series connectors.

A word „versatility“ describes well know series Hirschmann ST (STA) perhaps the best. ST connectors are universal because as for parameters, they´re sufficient for majority of applications (16A/250VAC) and they maintain a decent compcáctness. At the same time, they´re available in many versions (M/F, panel/ cable) , so we can create a desired combination – cable/cable, cable/panel.

ST connectors have 2,3,4 or 5 contacts + PE in a compact polyamid (PA) body. Safety and reliability is supported by a metal lock STASIx (bought separately), preventing accidental disconnection and also enabing a fast disconnection in case of necessity.
Connectors for a cable are also available Kwith an extra cable support against pulling off from a cable gland („strain relief“). ST series is so to say a standard for many industrial applications and it finds its place also for example in building automation (intelligent houses, ….).

A novelty in our portfolio is price-gainful set called SETSTAx3 for a cable+cable connection, containing STAS 3N, STAK 3N and a metal lock.

Detailed information will provide you datasheets at particular types below this article. Upon order, even the surface mount types and types with an integrated cable are available.

Top-class component should be equipped with a top class documentation. That´s also a case of many AC/DC and DC/DC modules series from Traco Power.

Demands of various application also vary. While somewhere it´s enough to know, that a given power supply will give us „some DC12V/1A“ or that a given „LED shines green and withstands 20mA“, in majority of cases we naturally need much more about a given component. Somewhere at the end of this chart are applications, where we need to know literally every parameter, including commonly non-mentioned parameters and graphs from a real measurement.

From this point of view, Swiss company Traco Power is really helpful at development and at selecting given AC/DC or DC/DC module, as all power modules are equipped with quality documentation in a form of detailed datasheets, certificates, 3D drawings and similar. Masterpiece – the application notes are available for several „high performance“ modules like for example TEN8WI module.

TEN8xxxxWI is the 8W DC/DC isolating module with a high energy density, enhanced range of operating temperatures and a wide input voltage range( 4:1). Besides a common documentation, there´s also available the TEN8WI application note, where we can find all important information for successful usage even in critical applications (EN50155-railways), including EMC characteristics, thermal consideration, recommended PCB layout and other.

For applications, where we don´t require that wide input voltage range, the standard TEN8 version (non- „WI“) is intended. In the TEN8 and TEN8WI families can be found a large amount of types with various input voltages (input 9-18VDC, 18-36, 36-75 or 9-36, 18-75 at the WI series) and 3.3 to 15Vdc output, including symmetrical ones (for example +-12V). On stock we keep a few versions, all other versions we´re able to supply you in a short leadtime.

Detailed information will provide you datasheets at particular types, as well as above-mentioned TEN8WI application note, TEN8WI certificate, TEN8WI-3D drawing and the TEN8 series filter design.
