The WTB16P-1H161120A00Z2 is a SICK W16-series photoelectric proximity sensor with background suppression, using a PinPoint LED visible red light source. It detects objects up to 1 m away, with a minimum sensing distance of 10 mm, and switches via IO-Link on a push-pull output.
Background suppression means the sensor reliably detects the target while ignoring reflective backgrounds beyond the set distance — critical for conveyor or pick-and-place stations where the belt or support surface could otherwise trigger a false reading. The 500 µs response time (cite:) is fast enough for most packaging and material-handling lines running at moderate speeds; for higher-speed applications (e.g., small-part counting at >1000 ppm) you would want a faster sensor. The IP66/IP67/IP69 protection rating (cite:) means this sensor body and optics withstand high-pressure, high-temperature washdown — suitable for food-and-beverage lines, dairies, or any environment where sanitation with caustic chemicals is routine. The 2 m cable termination (cite:) is a fixed lead; if your panel layout calls for a quick-disconnect, the sibling with an M12 connector (WTB16P-24161420A00Z2) is the drop-in swap without rewiring the sensor head.
This class of sensor — a photoelectric proximity sensor with background suppression — is used across automated production lines for presence/absence detection, position verification, and part counting on conveyors, packaging machinery, and assembly stations. The 20 mm wide housing (cite:) fits standard DIN-rail mounting or direct bracket attachment in tight machine frames.
