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 R2 standard size SMD reed sensors are designed for carrying moderate current and have an SMD pitch which is slightly wider than the miniature 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 and release AT, 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. All dimensions are in mm.
