Its PNP output switches at 500 µs, making it suitable for object detection on fast-moving conveyor lines or packaging machinery where cycle times are tight. Rated IP67, the housing withstands washdown environments and dusty factory floors — common on food-and-bev or automotive assembly lines where hose-down cleaning is routine. The 11 mm wide, 31 mm tall, 20 mm deep housing fits into tight panel layouts and mounts via through-hole or bracket. The M8 male connector simplifies field wiring — no cable gland needed, just a standard M8 mating cordset. Operating voltage range of 10–30 VDC. Load current is 100 mA. ## Switch-selectable logic Light-ON / Dark-ON switching is selectable on the sensor, so the same part adapts to either presence-detection or gap-detection logic without changing the wiring or adding a NOT gate in the PLC program.","metaTitle":"WL100-2P4429 SICK Retro-Reflective Sensor, PNP, 3 m, IP67","metaDescription":"SICK WL100-2P4429 photoelectric retro-reflective sensor, PNP output, 3 m sensing range, 500 µs response, IP67, M8 connector.

The WL100-2P4429 uses a single housing with a reflector, so a direct drop-in replacement without rewiring is not possible."},{"question":"What is WL100-2P4429's width?","answer":"The WL100-2P4429 has a width of 11 mm."},{"question":"Will WL100-2P4429 fit a panel designed for WS/WE100-2P4439?","answer":"Yes, the WL100-2P4429 shares the same 11 mm width, 31 mm height, and 20 mm depth as the WS/WE100-2P4439, so the mechanical footprint and mounting holes are identical. However, the WS/WE100-2P4439 is a through-beam pair requiring two housings and wiring for both emitter and receiver, while the WL100-2P4429 is a retro-reflective sensor needing only one housing plus a reflector.
