IR-xxxx Reed Sensor with Integrated Resistor
This reed sensor is built with an internal resistor which can either be used for level sensing applications or for contact protection. A diode can also be put in place of the resistor and the dot marked on the sensor can be used to denote the polarity. Various activating distances are available depending on the magnet and then 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 conform 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. A ring magnet can also be used around the sensor, for use in float applications.
