Dwyer Series DT Detector™ Position Sensor

Reliable Magnetic Point Sensor, Stainless Steel Housing, AC or DC

UL rated, Proximity Detector™ Position Sensors are reliable, magnetically actuated, stainless steel, completely interchangeable with competitive units and AC or DC for user friendly operation. They have no moving parts, eliminate costly seal fittings and offer enhanced reliability by eliminating arcing. Unintentional actuation by metals is not a problem.

The sensor consists of a durable hermetically sealed reed switch potted in stainless steel housing and a separate 316 stainless steel magnetic actuator bolt. Sensing distance is 0.1" (2.54 mm) for the standard actuator. Greater sensitivity of a larger magnetic actuator increases the sensing distance to 0.5" (12.7 mm).

The Detector™ is excellent for hazardous and corrosive environments, solid state and intrinsically safe applications, and may be mounted in any in any position. For installation in hazardous locations be sure to check local electrical codes. The Detector™ meets NEMA 1, 3, 4, 4X, 6, 7, 9, 12 and 13; and is certified Class I, Groups A, B, C and D; Class II, Groups E, F and G, Divisions 1, 2 and 3, and IP68 submersible.  Dimensional Information
