Drawing of R2E-S Latching SMD Reed Sensor R2E-S Gull-wing SMD Formed Reed Sensor Pad Layout Drawing of R2E-F Latching SMD Reed Sensor Drawing R2E-F Low Profile SMD Formed Reed Sensor Pad Layout Drawing of R2E Reed Sensor Carrier Tape Description
bi-stable reed sensors are built with an inbuilt biasing magnet. As they are molded with pre-flattened leads, no shock is transferred into the device when SMD formation takes place. Various latching/unlatching distances are available depending on the magnet used. The sensors are tested 100% for Operate AT, Release AT, Static 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. All dimensions are in mm. Electrical
