ULTRA-HIGH DENSITY 4MM REED RELAYS

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.
  • Insulation resistance greater than 1012 Ω
  •  Many benefits compared to industry standard relays. Learn more here >.

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.
