Ideally suited to the needs of Medical, Industrial, Instrumentation, Automotive, and
other applications where small size, zero power operation, and directional magnetic
0.84(0.033)
sensitivity are required, the RedRock
™
MEMS-Based Reed Sensor is a single-pole,
single throw (SPST) device with normally open ruthenium contacts. The sensor may
1.35(0.053)
be actuated by an electromagnet, a permanent magnet, or a combination of both.

Notes:
1
Individual switches may vary in magnetic closure sensitivity by
±
4 mT (Model K) or
±
7 mT (Model J) from the typical value.
If your application requires a different sensitivity range, please contact Coto at
redrock@cotorelay.com.
2
Life 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, 110 Hz - 3 kHz), 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.
