10W reed relay suits high-PCB-density applications

Pickering Electronics has added a new 10W-rated reed relay to its successful 4mm product family which features devices that occupy a PCB footprint of only 4mm x 4mm, facilitating the highest packing density currently available.

The Series 122 relays measure 12.5mm in height and are rated with a switching current of 0.5A at 10W. 3V and 5V coils are also available.

Fast operate and release times, typically 150 μs or less, make the Series 122 relays suitable for high speed test systems such as A.T.E. switching matrices or multiplexers. The 1 Form A (SPST) Normally Open (NO) Energize-to-make devices feature high-quality, instrumentation-grade sputtered-ruthenium switches and plastic packages with internal mu-metal magnetic screening to avoid the risk of magnetic interaction issues in densely-packed applications.

Devices have an insulation resistance of greater than 1012Ω and are 100%-tested for dynamic contact resistance to guarantee performance.

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.
