Highlights

Normally Closed form B contact 5.0W Contact Rating Does not require power for operation  Sputtered Ruthenium contact  Polarity Sensitive  Two types of lead configurations  Three magnetic sensitivity bands  Molded with internal blades parallel to SMD feet  Packed in tape and reels conforming to IEC-60286-3 norms  RoHS Compliant and Lead-free  Not Sensitive to ESD

Description

These ultra miniature normally closed SMD reed sensors are built with an biasing magnet. As they are molded with pre-flattened leads, no shock is transferred into the device when SMD formation takes place. Various activating distances are available depending on the magnet and the AT band used. The sensors are tested 100% for Operate AT, Release AT, Contact Resistance and Variable Contact Resistance before packing. Opposing poles of magnet and sensor cause this normally closed sensor contact to release. Like poles do not cause a release. Choosing the right AT band, magnet strength, and operating axis, will restrict the number of operates and releases to one.
