Description

This micro 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.
