Pickering Electronics’ ultra-compact 10W reed relays at ITC 2019Pickering Electronics will be showing a new 10W member of its successful 4mm2TM product family at International Test Conference being held in Washington D.C. In common with existing reed relays in the family, new Series 122 devices occupy a PCB footprint of only 4mm × 4mm, facilitating what is claimed to be the highest packing density currently available. These low-profile relays are just 12.5mm high, have a rated switching current of 0.5A at 10W and can be operated at 3V or 5V. The new reed relays have an insulation resistance of greater than 1012ohm and are 100 per cent tested for dynamic contact resistance to guarantee performance.

Series 122 relays offer fast operate and release times of typically 150 μs or less and are suitable for high-speed test systems including A.T.E. switching matrices or multiplexers. The 1 Form A (SPST) Normally Open (NO) Energize-to-make devices feature highest quality, instrumentation-grade sputtered-ruthenium contacts and feature internal mu-metal magnetic screening to avoid the risk of magnetic interaction issues in densely packed applications. The Devices have an insulation resistance of greater than 1012ohm and are 100 per cent tested for dynamic contact resistance to guarantee performance, and are enclosed in plastic packages.

Other members of the family include the Series 120 which has a switching rating of up to 1A at 20W and a height of 15.5mm, and the Series 124 which has a lower 9.5mm profile and a slightly lower rating of 0.5A at 5W.

Keith Moore, CEO at Pickering Electronics comments: “This new Series 122 device fills the gap between our first 4mm2TM product, the Series 120, which has a switching rating of up to 1A at 20W and a height of 15.5mm and our Series 124, which we launched last year, with has a lower profile of 9.5mm but with a slightly lower rating of 0.5A at 5W. We can now provide customers with the flexibility they need to design in a product that exactly matches their requirements.”

For ease of servicing/replacement, relays maybe socketed using SMD or through-hole sockets. However, care must be taken to mitigate the risk of affecting contact resistance integrity.
