REDROCK™ MEMS-BASED REED SENSOR
Top View
RedRock™ MEMS-Based Reed Sensor
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

be actuated by an electromagnet, a permanent
magnet, or a combination of both.

Notes:
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 [email protected].
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.
