Description
These R5 ultra-miniature SMD reed sensors are designed for signal switching applications and have a size 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. 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.
