The SE-31-IS Ultrasonic Sensor is specifically designed to perform in hazardous locations, Class I, Division 1, Groups C & D. Ideal for guiding thin or clear films, as well as most opaque webs, this sensor is fully certified under UL, cUL (US and Canada), and CENELEC (Europe).

The SE-31-IS has control range of 7.62 mm (0.3 inch), a sensing gap of 50.8 mm (2.0 inches), and requires the same 12 VDC power supply as most other Fife sensors. The maximum sensor voltage and current is protected through a safety barrier
located outside of the hazardous area. Maximum cable length from the sensor to the controller is 4.19 m (165 feet).
