Through-beam optical sensors for counting and position detection.
Optical Slot Sensors
Optical Slot Sensors combine an emitter and receiver in a single U-shaped housing, detecting objects that pass through the slot. They provide fast, non-contact detection of parts, labels and moving products, ideal for high-speed counting and positioning.
Widely used on packaging lines, labeling machines and feeder mechanisms, these sensors offer quick response, easy alignment and NPN/PNP output options with LED indication.
Accurate sensing of metals, materials and motion.
No mechanical wear - sensors last years in service.
Sealed housings resist dust, oil and moisture.
Standard M8, M12 and M30 thread mounting.
Consistent NPN / PNP signals for any controller.
