Benefits

Omni-polar. Does not require power for operation. Sputtered Ruthenium Contact. RoHS Compliant. Not ESD Sensitive.

Description

This ultra miniature PCB mountable reed sensor is designed for switching 10W.  The internal blades always parallel to the top surface of the sensor. The sensors are tested 100% for operate and release AT, Contact Resistance and Variable Contact Resistance before packing. 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.
