Description
This standard size PCB mountable reed sensor is manufactured to carry up to 1.5A. 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 AT, Release AT, Static Contact Resistance and Variable Contact Resistance before packing. Our products are completely Lead-free and conform to the RoHS directive.
Applications
This reed sensor is suitable for use in the following applications and in many others: microphones and radio transmitters, copier and scanner doors, coffee machines, rowing electronics, power switches in explosive areas…

Possible magnet actuations
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.
