RedRock™ MEMS-Based Reed Switch

Introducing RedRock™ Ideally suited to the needs of Medical, Industrial, Automotive, and other applications where small size, zero power operation, and hot switching capabilities are required, the RedRock™ MEMS-Based Reed Switch is a single-pole, single throw (SPST) device with normally open ruthenium contacts. The sensor may be actuated by an electromagnet, a permanent magnet, or a combination of both.

  • 1.11mm² Footprint – World's Smallest Reed Switch
  • 6mW Switching Power
  • Highly Directional Magnetic Sensitivity
  • Hot Switchable
  • 50 G Shock Resistance
  • Broad Operating Temperature Range
  • Hermetically Sealed
  • RoHS Compliant
  • Tape and Reel Packaging

Notes:

1 Individual switches may vary in magnetic closure sensitivity by ±4mT (Model K) or ±7mT (Model J) from the typical value. If your application requires a different sensitivity range, please contact

2 Expectancy defined as mean cycles before failure with end of life defined as contact resistance >1000 W.

3 Functional Vibration Resistance is defined as the mechanical-only force (in G,110Hz-3kHz), that a switch can withstand without causing a contact closure.

4 Functional Shock Resistance is defined as the mechanical-only force(in G), that a switch can withstand without causing a contact closure.

5 Shear Force is the mechanical force (applied to the top half, in a plane parallel to the PCB) that a switch can withstand without causing damage to the switch.
