Sick WL9L-3P2232 photoelectric sensor
The Sick WL9L-3P2232 is a compact retro-reflective photoelectric sensor with autocollimation and a visible red laser. It provides PNP complementary output for industrial detection tasks. The rectangular plastic housing measures 12.2 mm by 49.8 mm by 23.6 mm and weighs 13 g. It suits automation engineers needing precise small-object detection.
Sensing range and output limits
Maximum sensing range reaches 12 m with a defined range up to 8 m. The laser spot measures Ø 1 mm at 500 mm distance. Switching frequency is 1,000 Hz with a 0.5 ms response time. Output current is limited to 100 mA. Supply voltage must stay between 10 V DC and 30 V DC with ripple below 5 Vpp.
Mounting and connection checklist
Verify an M3 mounting hole pattern fits your bracket. Confirm an M8 4-pin male connector matches your cable assembly. Ensure ambient temperature stays within 10 °C to +50 °C for standard operation. The IP66, IP67 and IP69K ratings suit wash-down environments. Check that PNP complementary switching matches your controller logic.
