Highlights

Does not require power for operation  Normally Open Form A contact  Sputtered Ruthenium contact  Omni-polar device; actuates with either pole of magnet  20.3 mm pin pitch  Three magnetic sensitivity bands  RoHS Compliant and Lead-free  Not Sensitive to ESD

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

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.
