SICK Retroreflective Photoelectric Sensor, Block Sensor, 0 → 18 m, NPN/PNP, IP67, IP69K

SICK W12-2 Laser Series Photoelectric Sensor, IP67, Laser Light Source - WL12L-2B530

This photoelectric sensor is a Compact retroreflective laser detector designed for industrial automation environments. It uses visible red laser light to sense objects at distances up to 18m with an autocollimation principle and is supplied with mounting clamps for panel installation. The device operates from a DC supply and provides selectable light/dark switching outputs via a 5‑pin M12 connection.

Features & Benefits

• 10–30 V DC supply enabling flexible system integration
  less than or equal to 200μs response time supporting high-speed detection
  Output current less than or equal to 100mA allowing direct drive of control inputs
  Metal housing with IP67 and IP69K rating resisting washdown
  Focusable optics from 300mm to infinity for varied target sizes
  Small laser spot Ø0.8mm at 300mm for detecting small parts

**Applications**

• Suitable for high-speed part detection on conveyor lines
  Ideal for presence monitoring of small components in assembly
  Used for distance sensing with retroreflective targets in packaging
  Can be used in washdown environments requiring IP69K protection

How is switching mode selected on the unit?

The switching behaviour is set via an L/D control on the connection cable permitting either light or dark switching.

What connection type is provided for field wiring?

A male M12 5‑pin connector is fitted for straightforward sensor/actuator cabling.

What optical class and Wavelength does the emitter use?

The emitter is a class 2 laser operating at 650 nm with a typical service life specified at room temperature.

What protection and interference features are present on the outputs?

Outputs include reverse‑polarity protection, interference suppression and overcurrent/short‑circuit protection as specified for different circuit types.
