The proximity sensor is suited for material handling, mobile equipment, industrial equipment, and food and beverage processing applications desiring reduced maintenance and fewer equipment breakdowns. The sensor is highly durable, does not require power, and operates across a wide temperature range. It provides a much more rugged alternative to the inductive proximity sensor and is far more reliable than a reed switch. Model 52M incorporates the GO Switch’s dry contact proximity sensor technology that uses magnets to control a set of contacts. Advantages include no power requirement; high reliability, tested to 5 million cycles at full-rated load; broad temperature range of -40 to 100 °C; polarity insensitivity, eliminating the need to specify NPN or PNP products; and high- and low-current compatibility (5 mA to 2 A at 24 VDC). With greater flexibility, one sensor can be used for a variety of applications, reducing part numbers and inventory.
