Industrial Photoelectric Retro-Reflective Sensor
The Sick WL18-3P430 is a compact photoelectric retro-reflective sensor with autocollimation designed for industrial detection tasks. Its rectangular ABS housing measures 17.6 mm by 75.5 mm by 33.5 mm and weighs 40 g. It operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 40 mA.
Sensing Range Up to 7 Metres
The sensor detects objects from 0 m to a maximum of 7 m using a visible red LED light source at 645 nm. The light spot reaches approximately Ø 40 mm at a 2 m distance with a 1.8° dispersion angle. Sensitivity is adjusted via a single-turn potentiometer for precise setup.
PNP Complementary Output with M12 Connector
This unit suits automation systems requiring a PNP complementary output with light/dark switching and a 4-pin M12 male connector. It delivers a switching frequency of 1,000 Hz and a response time under 500 µs. Builders needing NPN output, a different connector type, or a through-beam sensing principle should consider alternative sensor models.

Questions about this item
How far can the sensor reliably detect a reflector in a typical installation?
The rated sensing range is 0 m to 5 m with a standard reflector; the maximum possible range reaches 7 m under ideal conditions.
What does the PNP complementary output mean for wiring into a PLC input card?
The sensor provides both light-switching and dark-switching PNP signals on the 4-pin M12 connector, sourcing up to 100 mA at 10–30 V DC.
Will the 17.6 mm wide housing fit on a standard DIN-rail bracket or tight machine frame?
The rectangular ABS housing measures 17.6 mm wide, 75.5 mm high and 33.5 mm deep, with an IP67 rating and a 4-pin M12 connector for compact mounting.
