"World's smallest" reed relay makes UK debut at EDS

9th October 2018

What is claimed to be the industry’s smallest reed relay will be displayed by Pickering Electronics at the upcoming Engineering Design Show, Ricoh Arena, Coventry (17-18 October). The Series 124 is part of Pickering’s new ultra-high density 4mm2 reed relay range product line, which takes up the minimum board area of only 4mm x 4mm, allowing the highest packing density possible.

Series 124 relays are also the lowest profile on the 4 x 4mm footprint, measuring just 9.5mm high. Devices are currently available in 1 Form A (energize to make) with options of 3 or 5 volt coils.

The reed relays feature a sputtered ruthenium switch rated at 5W, 0.5A. These are the same reed switches as used in the long-established Pickering Series 111, 111P and 117, but are orientated vertically within the package, facilitating such high density.

The relays boast very fast operate times, typically 80µs, making them ideal for high speed test systems, and due to the incredibly small size they are also suitable for very high-density applications such as A.T.E. and Semiconductor switching matrices or multiplexers.
