Product Overview
The SensorsX SX-OMPHB series is a fork-type photoelectric sensor for detecting opaque labels and the gaps between them. It uses a 940 nm infrared light source and provides a maximum switching frequency of 10 kHz with a response time of 50 µs or less. The 3 mm-wide, 60 mm-deep slot accommodates the label web during detection. SET-button teaching, LED indicators and automatic level control simplify setup and threshold adjustment. The metal housing provides IP65 protection, with NPN or PNP models, cable or M8 connector versions, and switchable NO / NC operation.
