Incorporating giant magnetoresistive technology, 3-wire dc proximity sensor detects magnets through all non-magnetizable materials. With switching frequencies of 5,000 Hz, polarity-independent sensor operates from -13 to +158°F and provides accurate position detection regardless of magnet orientation. Tubular-style models are Type 316 SS quick-disconnect types in M8, M12, and M18 dia housings. For washdown applications, IP69K-rated models are available in Ml2 and Ml8 dia housings.
