Pickering Electronics has introduced a single-in-line reed relay  family that mounts on a 0.25inch pitch while switching 80W or 2A. Called Series 144, they feature sputtered ruthenium contacts so they can switch at high power and low-level signals. There is also an internal mu-metal screen to eliminate magnetic interaction between closely stacked devices. Maximum carry current is 3A in all ...

Würth Elektronik is promoting PCBs with press-fit power connectors as the interconnection technology of choice for high-voltage power distribution in mobile machines and commercial vehicles. It has a design service for vehicle companies seeking custom power distribution units that handle between 60 and 1,000V “that are compact, robust and can be flexibly configured”, it said. “Press-fit technology makes it possible ...

Bourns has created a series of self-resetting fuses that can carry from 12 to 20A at 60°C. Called Model NX, they measure 2.8 x 9.8mm including two 2.8 x 2.5mm flat connecting tabs, one at each end. Height is just under 1mm. “While our new Model NX Series has the same footprint as our Model NR series, it can carry ...

Toshiba is eyeing semiconductor test applications with a tiny photo-relay that operates at 1.6Vin “making it suitable for use with 1.8V FPGAs”, according to the company. “A resistor is built in on the primary side, enabling voltage-controlled operation.” Called TLP3412SRLA, it draws 6.6mA at the nominal operating voltage of 1.8V. Inside is a single Form-A (normally-open) ac or dc contact that ...

Maxon has introduced a controller board for brushed DC and brush-less dc motors up to 1,800W (30A) continuous duty and 3,600W (60A) peak, designed for integrating inside products. Operation is across 10 to 60V and -30 to +25 °C (+75°C with derating). Called ESCON2 Module (part 783722), it is a four-quadrant device that can drive and brake in both direction, ...

ABB has created a liquid cooled synchronous reluctance motor series that achieves IEC international efficiency class 5 (IE5). It brands its synchronous reluctance motors ‘SynRM’, and is offering liquid-cooled versions across 37 to 710kW (400V in IEC 200-315 frame sizes (aluminum, steel on request). “A major advantage of the IE5 SynRM liquid-cooled motors is that they are much more efficient ...

RS is stocking five kits of hand soldering and re-work components aimed at different applications, such as micro-soldering and de-soldering larger components. They collect together units selected from Weller’s WXsmart soldering component range. All the kit part numbers are of the form T005345x699, and all of the kits include get Weller’s ‘WXsmart Station’ controller, a soldering iron, a stand for ...

Pickering Electronics had added a single-in-line reed relay which can stand-off 5kV and switch 1.5kV to its Series 104. Inside is a single-pole normally-open contact (‘1 Form A’). Footprint is 6.22 x 24.1mm, and the relays stand 8.1mm tall above the PCB. “This is particularly advantageous where a compact design is essential, as the devices can stack at just 6.35mm,” ...

Looking like a general-purpose problem solver for process control, Teledyne Relays has introduced a seven-function DIN rail mount timing relay that works over 100ms to 100 hours and offers a 5A 240Vac change-over (SPDT) contact, that can handle “small inductive loads” at 2.5A. Operation is over a wide range of ac or dc supplies. There are two versions: MFT02A12 12-240Vdc ...

Panasonic has launched a series of 70A PCB-mount power relays designed to US standards “The HE-R2A relay series is suited for modern wall box designs, and we are happy that we can offer a UL508-compliant sibling of the HE-R type for European four-phase systems, enabling the consolidation of switching functions onto PCBs with space savings,” said Panasonic product manager Bernd ...
