Industrial Detection Sensor
The SICK WL100-P4429 is a photoelectric retro-reflective sensor designed for automated detection tasks. Its PNP switching output and selectable light/dark mode suit industrial control systems. The unit operates on a 10 V DC to 30 V DC supply with a maximum current draw of 30 mA. It targets engineers integrating presence sensing into conveyor or packaging lines.
Compact IP65 Housing
A rectangular ABS/PC/POM housing measures 11 mm by 31 mm by 20 mm and weighs 9 g. The enclosure achieves an IP65 rating for dust and water-jet protection. Connection is made through a male M8 4-pin connector. A stainless steel mounting bracket and a P250 reflector are included in the package.
2.6 m Sensing Range
The sensor detects objects from 0.01 m up to 2.6 m using a visible red LED at 680 nm. A potentiometer allows 270° of adjustment for precise threshold setting. Response time is 0.5 ms at a 1,000 Hz switching frequency. The special optical design enables reliable detection of transparent materials. Not suitable for applications requiring sensing distances beyond 2.6 m or AC voltage supply.

Questions about this item
What voltage range does the M8 connector support?
The sensor operates on 10 V DC to 30 V DC with a ±10 % ripple allowance.
What mounting hardware and reflector are included in the box?
A stainless steel bracket (1.4301/304) BEF-W100-A and a P250 reflector are supplied.
How do you select between light and dark switching on the rotary switch?
Turn the 270° potentiometer to the desired position; the selector is a physical rotary switch on the housing.
