MS-10x Standard Size, PCB Mountable Reed Sensor Series

Does not require power for operation

Normally open (NO) form A contact

Omni-polar device; actuates with either pole of magnet

Two different pin pitches

Three magnetic sensitivity bands

RoHS Compliant and Lead-free

These reed sensors are manufactured to carry up to 1.5A and are available in two pin-through-hole PCB mounting pitches. The internal blades always parallel to the top surface of the sensor. Change-over versions can also be built on request. All sensors are tested 100% for operate and release AT, contact resistance and variable contact resistance before packing. Our products are completely Lead-free and conform to the RoHS directive.

Possible Magnet Actuations

PCB Mountable Reed Sensor Actuation Examples

A few examples of magnet actuation are shown above. Being an omnipolar device, this sensor can be actuated with either a north pole or a south pole or both. Choosing the right AT band, magnet strength, and operating axis, will restrict the number of operates and releases to one.
