Pickering Electronics has extended its 4mm product family with the Series 122 reed relay. Used in high speed test systems, occupying a PCB footprint of 4x4mm, Pickering claims the relay provides the highest packing density currently available.
The relay measures 12.5mm in height and can operate from 3V or 5V. Its contacts are rated with a switching current of 0.5A at 10W.
Featuring instrumentation-grade sputtered-ruthenium switches, the 1 form A (SPST) normally open energize-to-make devices have plastic packages with internal mu-metal magnetic screening to avoid cross-interference and ‘false’ switching in densely packed applications.
Devices are tested for dynamic contact resistance and have an insulation resistance of greater than 10¹²Ω.
The relays may be socketed using SMD or through-hole sockets. However, care must be taken to mitigate the risk of affecting contact resistance integrity.
The Series 122 reed relay is suitable for test systems such as A.T.E. switching matrices or multiplexers, Pickering says.
Keith Moore, CEO at Pickering Electronics says “We launched our first 4mm2TM product, the Series 120, 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. We can now provide customers with the new Series 122 device which fills the gap in our product range and offers the flexibility required to design in a product that exactly matches their requirements.”
Pickering will be showing the Series 122 relays at Productronica in Munich, 12-15 November.
