The Series 120 reed relay range takes up the minimum board area making them ideal for very high density applications such as A.T.E. switching matrices or multiplexers. Requiring a board area of only 4mm x 4mm, these relays allow the highest packing density currently available.

Two switch types are available, a general purpose sputtered ruthenium switch rated at 15 Watts, 1 Amp (3 volt version) or 20 Watts, 1 Amp (5 & 12 volt versions) and a low level sputtered ruthenium switch rated at 10 Watts, 0.5 Amps.

Pickering Series 122

10 Watts, 0.5 Amp Switching
Single Pole Single Throw Reed Relay
Taking up the smallest PCB area of only 4mm x 4mm

  • 3 or 5 Volt coils
  • Fast operate and release times, typically 150 μs or less, make the relays ideal for high speed test systems.
  • 1 Form A (SPST) Normally Open (NO) Energize to make.
  • Suitable for A.T.E. switching matrices or multiplexers.
  • Internal mu-metal magnetic screen allows ultra-high PCB packing density, saving significant cost and space.
  • 100% tested for dynamic contact resistance for guaranteed performance.
  • Formerless coil construction maximises magnetic efficiency causing faster switching speeds and an extended lifetime.
  • Many benefits compared to industry standard relays. Learn more here >.
  • Insulation resistance greater than 1012 Ω

The Series 122 10W rated reed relay is part of the successful 4mm2 TM product family that occupy a PCB footprint of only 4mm x 4mm, facilitating the highest packing density currently available. 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 available.

The device has pins on a 2mm square pitch. There are suitable connectors available from some manufacturers, both SMD and Through Hole, that will allow these relays to be stacked in either a row or in a matrix on a 4mm pitch.

If a higher rating is required, please consider our Series 120 which are rated up to 1.0 Amp at 20 Watts but with a higher profile height. If a lower profile height is required, please consider our Series 124 with a height of just 9.5mm whilst rated up to 5 Watts, 0.5 Amps switching.
