Highlights
♦ Normally Open Form A contact ♦ 10.0W Contact Rating ♦ 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. 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.
