Slot and Label Sensors

Slot and label sensors detect objects that pass between two arms—one with the emitter and the other with the receiver. The fixed slot width provides reliable opposed-mode sensing of objects as small as 0.30 mm. This makes slot sensors ideal for counting, sensing parts on conveyor rails and belts, detecting edges, and other applications.

Label sensors feature slots that are just wide enough for labels to pass through. They are designed to reliably detect either the labels or their backing for use in labelling equipment. These rugged, high-speed sensors have a response speed of up to 40µs (12.5 kHz switching frequency) for increased position accuracy.
