R5 Ultra-Miniature SMD Reed Sensor
These SMD Ultra-Miniature 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 actuating distances are available depending on the magnet and the AT band used. These Ultra-Miniature Reed Sensors are tested 100% for Operate AT, Release AT, Static Contact Resistance and Variable Contact Resistance before packing. Being an Omni-polar 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.
