New reed relay ideal for high-PCB-density applications

Pickering Electronics has introduced a new 10W-rated reed relay to its 4mm2TM product family which provides devices that occupy a PCB footprint of only 4mm x 4mm, promoting the highest packing density. 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 150μs or less, make the relays excellent for high-speed test systems such as ATE switching matrices or multiplexers. The 1 Form A (SPST) (NO) Energize-to-make devices feature the highest-quality, instrumentation-grade sputtered-ruthenium switches and plastic packages with internal mu-metal magnetic screening to evade the risk of magnetic interaction issues in densely-packed applications. Devices have an insulation resistance of greater than 1012Ohm and are 100%-tested for dynamic contact resistance to ensure performance.

Comments Graham Dale, technical director at Pickering Electronics: “The Series 120 - our first 4mm2TM product - was launched with a switching rating of up to 1A at 20W and a height of 15.5mm. Last year, the Series 124 reduced this profile to 9.5mm but with a slightly lower rating of 0.5A at 5W. This new Series 122 device, therefore, fills the gap, providing customers with the flexibility they need to design in a product that exactly matches their requirements.”
