Highlights

Omni-polar 10.0W Contact Rating Does not require power for operation Normally Open, Form A contact  Sputtered Ruthenium contact 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 miniature SMD reed sensors are designed for low power, high speed switching applications, and have a cost advantage over the standard size SMD reed sensor. 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, Static Contact Resistance and Variable Contact Resistance before packing. Our products are completely Lead-free and conforms to the RoHS directive. 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.
