With its width of only 5mm is this relay able to switch 6A/250VAC, moreover at a minimum coil power consumption.

Thin as about a block of “Domino” and still so powerful and for a reasonable price – these are narrow relays series FTR-LY. Powerful and still so easily usable even in circuits with a 5V logic … Somehow this way could be described the well proven relays of FTR-LY series.

If you´d like to use a relay of this shape, then the FTR-LY series will probably also fulfill all your expectations regarding lifetime, reliability, low power consumption and other. When selecting a suitable type, it´s good to take in mind a material of contacts – on stock we keep three types (5V, 12V and 24V DC). A novelty in our portfolio – type FTR-LYCA005V has a „V“ suffix, what means AgSnO2 + Au (0.3µm) contacts. The biggest advantage of a golden layer on contacts is a very low minimum switching current through contacts (10mA/5VDC), in comparison to types with a suffix „E“ or „Y“, which have a minimum switching current 100mA/5VDC. Types FTR-LYCA012Y and FTR-LYCA024Y have in summary the same good properties, only they´re not suitable for switching of currents below 100mA (worse self-cleaning ability of contacts).

An advantage is up to 4000VAC (coil/ contacts) isolation and an isolation distance (clearance/ creepage) is 8/ 8 mm. To a reliability even in tiny areas on a PCB also contributes a max. operating temperature up to +85°C and a low power consumption (approx. 170 mW). Types, which we keep in stock are with one changeover contact (1CO, SPDT), that´s why they can be freely used in application where you need an NO or NC contact.

Upon order, there are also available types for socket and the PCB socket (JM-6N). It´s beneficial for applications, where we want to maintain a possibility to easily exchange a relay.

Detailed description can be found in the Fujitsu FTR-LY datasheet.

Connectors of the PV, SV and SH series are available in a huge amount of versions and sizes, that´s why you´ll certainly find here a suitable type for you.

A very frequent requirement for a simple and reliable connection of wires to a PCB is actual about as long as the world knows plated copper boards. There are many solutions and producers, thus a choice of suitable type is usually a question of your preferences, requirements of a device, availability, offer of distributors,….

Even in our store can be found various solutions from world-class producers like TE Connectivity (Tyco, AMP), Wago, Phoenix Contact and also from company Euroclamp. Just the last one mentioned – Euroclamp, focuses mainly on PCB terminals, what is reflected in a wide offer. From our experience we can confirm a quality and reliability of these connectors. To the most favorite ones belong series PV, SV and SH, what are plug-in connectors (terminal blocks) for PCB and the mating types for a cable. They´re available in pitches of 2.5mm/ 2.54mm/ 3.5mm/ 3.81mm/ 5.0 mm/ 5.08mm/ 7.5mm/ 7.62mm/ 10.0mm/ 10.16 mm. So as to make you a selection of a right type easier, we bring you a few hints and explanations regarding their description.

PVxx – main type for a PCB (connector with pins).
Example: PV02 (02-24= number of poles) – 5.08 (pitch of pins) – V (V-vertical, H-horizontal)- M (M-modular, P-closed)

SVxx – connectors (female) for a cable – intended for connection with the PVxx series
SV02 (02-24= number of poles) – 5.08 (pitch) – P (P – rear wire connection, F- frontal wire connection) – * (additional code, for example „K“= version with side screws)

SHxx – right angle cable connectors (female) – intended for connection with the PVxx series)

A very useful “complement” of these series is also the SFxx , series, i.e. – a terminal block enabling a “wire to wire” connection (with types SVxx or SHxx). It can be very convenient if we for example want to jump some module and to maintain input and output leads interconnected (enable to make for example various versione of the same product. A novelty in the Euroclamp portfolio is also the PF series – for a PCB (female connector), enabling connection with PF – (male connectors).
A common feature of all PVxx connectors is a relatively high current handling ability – for example 12 (16)A/450VAC at types with 5.0 or 5.08mm pitch and a maximum wire cross section of 4/2.5 mm2 (solid / stranded wire). Body of connectors is made of a rigid self-extinguishing polyamide (UL94-V0) and the connector itself is made of nickel plated copper alloy. Basic color of these connectors is green (RAL6032) but upon order they´re also available in other colors (grey, black, blue, red, yellos, brown and other). A considerable advantage is also a wide range of operating temperatures of -40 to +130°C.

Types with a wide pitch (for example 10mm) are physically the same with types with a half pitch ( 5mm), they only differ in omitted pins and naturally the maximum allowed voltage is higher (750VAC). Perhaps the best idea about possibilities of these „plug-in“ connectors will give you attached pictures. Detailed description can be found in the Euroclamp short-form catalogue, in the main catalogue Euroclamp, as well as in datasheets at particular types.

Bare wires going from a tested device do not have to mean a problem or require a long time to connect to a power supply.

Who wouldn´t know it – a tested device on a workbench has only wire leads (without any connectors) and we just want to connect it to a power supply simply and reliably. If you don´t want to laboriously connect banana plugs to wire leads (what we surely don´t want if the test is supposed to last only a while :-)) we have only a possibility to use screw terminals on a given laboratory source. But usually neither this isn´t an ideal solution, as the openings in such terminals are usually quite small and if we want to put a wire only “between two pads” – it usually falls out at tightening…

Fortunately, there is one very handy component – „WAGO banana plug“, i.e. banana plug with a spring clamp into which it´s possible to insert a wire immediately and without any tools. Similarly simply we´re able to loosen it in a fraction of second – by pressing a body of a plug. The principle of a terminal is the same as for example in lighting connectors Wago 224 series.

We believe that you´ll like this useful helper and you´ll find it belonging to a “must have” category. On stock we keep three color versions (black, red and blue) as well as a set of 50 pcs Wago 215-111 (mix of 5 colors in 10 pcs). Upon request we´re able to supply you any other color version.

Detailed description can be found at particular types.

Finder monitoring relays are able to effectively signalize a fault status in a mains line and to prevent damages or undue wear-out.

Too high or too low voltage, phase loss or a wrong phase rotation are conditions commonly occurring in an industrial environment. Even though a phase rotation is usually stable, but only one improperly connected lengthening cable is sufficient …. These fault conditions harm to typical 3-phase devices like for example motors and as for a voltage out of tolerance – this usually doesn´t make well to any device. Devices like compressors and gas discharge lamps even don´t like too often switch on/ off (cycling) in case of fault conditions in the mains power line. There is a solution for all these cases – in a form of a simpler of a more sophisticated monitoring relay.
In our offer can be found high-quality components from company Finder – a producer with long-term experience in production of relays. To components intended for monitoring of mains line belong for example series F70 and F71, from which we keep in stock these types:

70.31.8.400.2022 – 3-phase electronic monitoring relay. Monitors low voltage (adjustable), high voltage (adjustable), window mode (low + high voltage), adjustable time delay of switching (trip), selectable fault memory, phase loss, phase rotation. Comprehensive indication of all statuses by means of three LEDs

70.61.8.400 – compact 3-phase electronic monitoring relay. Monitors phase rotation and phase loss.

71.31.8.400.1021 – 3-phase monitoring relay. Monitors low voltage (adjustable), high voltage (overvoltage), adjustable time delay of switching (trip), selectable fault memory.

All above mentioned types have on their output a small relay (6 or 10A), which can serve for controlling of a main contactor or directly for switching of other devices in case of faulty status. Adjustable time delay at types 70.31 and 71.31 functions in a way that after detection of a fault a relay “waits” for a selected time and if a fault still persists, the relay will switch on an output contact. In other words – monitoring relay ignores faults shorter than a selected time (0.5-60s at type 70.31 and 0.1-12s at type 71.31). This function is very useful to prevent an undue frequent switch on/off of devices, which are able to withstand a short-time fault status without a damage.

Memory function is also a useful function, which – if active, will prevent a repeated start of a device. This is very important for example at devices, which mustn´t be switched on without an operating personnel.

Detailed description can be found in datasheets at particular types.

Do you have an application where a black switch is not suitable? We have an elegant white one for you.

Rocker switches are available in a vast majority in a black version. When we take a look at catalogues of renowned producers we´ll usually find there mainly black types and only a few white ones. However a switch in a black version can be advantageous in many applications like office devices, PC, “white” (home) goods, lighting, equipment, but also in many other devices having enclosure other than black, or where just a white version can be an interesting design element. Even in our electronic branch it´s particularly true, that a “package sells” and an aesthetic design of a device can be one of the factors of a market success.That´s why you can find in our stock two novelties – a white rocker switch 1832.3311 ((DPST, 20A/250VAC) as well as a round 1881.1105 (SPST, 12A/250VAC). Both novelties belong to well proven series with widely known properties. Detailed description can be found in 1830 and 1881 series datasheets.

Recently we added into our standard stock offer also many other types from Marquardt and you can find them below this article.

Water, dust, mud, chemicals,… multi-pole industrial connectors Hirschmann CM will handle it easily.

Plastic- or a metal connector? Majority of designers will probably place on the first place in a virtual “quality chart” a connector with a metal body. It´s often true, but it needn´t be always so. Apart from the fact, that a metal connector is usually more expensive, often – mainly in a corrosive environment a metal body isn´t advantageous. Modern high-strength plastics, often glass-reinforced reach strength fully sufficient to create a rigid and reliable connector. This can be seen for example in connectors from company Hirschmann (a member of Belden group) CA3 or CA6 series, which we introduced to you in our article A connection resistant to dust and water – Hirschmann CA series and also in multipole connectors CM series, which we´d like to introduce to you in this article.

CM series is in general very similar to the CA series as for the design, robustness and materials used. Connector body is from the fiberglass reinforced polyamide, contains silver-plated contacts and has IP rating 67. Also range of operating temperatures is very high – from -40 to +90°C.

Main difference is, that these connectors are compatible to MIL-C 5015 resp. VG 95 342 and are available with 4-17 poles (4,5,6,6+PE,7,14,17). All versions of the CM series handle 50V AC/DC and 4-10A currents, depending on the type. CM06 are F connectors (socket) for a cable and mating types are CM02E – i.e. Male panel connector. The only exception are connectors CM02L (6 poles+PE) with a metal body. Also available are CM02SD covers and a sealing CM02D.

On stock we have the biggest – 17 pole version CM06EA20-29S and CM02E20-29P.

Detailed information will provide you datasheets at particular types and a list of available types can be found in the Hirschmann catalogue.

Low profile, higher safety and a wide spectrum of power ranges ensures, that in the TBL series you´ll find the right type for your demands.

Quality AC/DC power supplies for industrial automation and equipment of buildings (intelligent houses, …) are one of the fundamental supposals of a successful and reliable application. But how to choose the “right one”? Sure, there´s a lot of criteria and one of them is the requirement to fit into flat – low profile distribution boxes. This requirement is well met in the Traco TBL series, with the height of only 54,5 mm (after attaching to a DIN rail). TBL series provides a high safety (safety class II) and meets for example UL 1310 class II requirements (15-90W models). A big advantage is a wide range of operating temperatures -25 to +70°C (up to +60°C without power derating).

TBL series is available in 5 power ranges from 15 to 150W and also available is the 60W backup source (UPS) TBL-BC comprising circuitry for battery management. If necessary, it´s also possible to adjust output voltage (5-5,2V, 12-16V, 24-28V) – for example to compensate long conductors to a target device. In respect to an overall design and a high reliability, the TBL series is also suitable for supplying of security devices (alarms).

Detailed information will provide you the Traco TBL datasheet, TBL series models list and installation instructions.
