Our smallest ultrasonic sensor, the SE-31 is ideal for guiding both clear and opaque materials. This temperature stabilized sensor is unaffected by optical variation or ambient light, eliminating the need for multiple sensors, and increasing productivity.

The SE-31 has a control range of 0.3” (7.63 mm), and a sensing gap of either 1” (25.4 mm) or 2” (50.8 mm). Improved circuitry reduces the effect of standing waves and temperature variations, which improves the overall operational performance of this sensor.
