Small rectangular metal photoelectric sensor with red laser, M12 5-pin connector, IP67 IP69K rating

Sick

Sick WL12L-2B530 Photoelectric Sensor NPN PNP 18m 650nm Laser Class 2 IP67 IP69K M12 5-pin

SKU CH-E2DJ-82PB9

A compact 15 mm × 49 mm × 41.5 mm photoelectric retro-reflective laser sensor detecting small or fast objects up to 18 m with selectable NPN/PNP output and IP67/IP69K metal housing

  • 18 m sensing range with 650 nm Class 2 laser
  • IP67 and IP69K metal housing resists wash-down
  • Selectable NPN or PNP output up to 100 mA
  • 5 kHz switching speed catches fast objects
  • 10–30 V DC supply fits standard control voltage

Sensing Range and Light Source

The SICK WL12L-2B530 is a photoelectric retro-reflective sensor with autocollimation designed for detecting small objects and items moving at high speeds. It operates with a visible red laser at 650 nm wavelength, producing a light spot of Ø 0.8 mm at 300 mm distance. The maximum sensing range reaches 18 m, making it suitable for industrial automation tasks requiring precise detection over distance.

Dual Output Configuration and Supply

This sensor provides both PNP and NPN switching outputs, selectable via the L/D control cable for light or dark switching modes. It accepts a supply voltage from 10 V DC to 30 V DC with a ripple of 5 Vpp and draws 55 mA. The output current is rated at 100 mA, with signal voltages defined for both output types, and a switching frequency of 2,500 Hz supports fast response applications.

Laser Class and Environmental Protection

The device meets Laser Class 2 according to EN 60825-1:2014 and IEC 60825-1:2007, ensuring safe operation in industrial environments. Its metal housing with PMMA optics achieves IP67 and IP69K enclosure ratings, resisting dust ingress and high-pressure washdown. Connection is made through a male M12 5-pin connector, and the unit weighs 130 g with dimensions of 15 mm x 49 mm x 41.5 mm.

Questions about this item

Can the 15 mm by 49 mm by 41.5 mm housing and M12 5-pin connector fit my existing mounting clamps and cable?

The rectangular metal housing measures 15 mm by 49 mm by 41.5 mm and includes two clamps; the M12 5-pin male connector matches standard M12 cables.

How do I verify the sensor is operating correctly after wiring?

The potentiometer adjusts sensitivity; the visible red laser spot of 0.8 mm at 300 mm confirms alignment, and the output toggles at up to 2 500 Hz with 200 µs response.

Which accessories are included and what must I purchase separately?

Two mounting clamps are supplied; an M12 5-pin cable, a compatible reflector for the 18 m range, and a 10 V to 30 V DC power source are not included.
