SICK Retroreflective Photoelectric Sensor, Rectangular Sensor

SICK W11-2 Series Photoelectric Sensor, IP66/IP67/IP69K, 30V DC Maximum Voltage - WL11-2P2432

This photoelectric sensor is a retro-reflective proximity device designed for industrial automation and detection tasks. It uses an LED light source and a reflexive sensing method to detect targets at a distance, and is engineered for installation where a Compact rectangular form factor and robust ingress protection are required. The device interfaces via a 4-pin connection compatible with M12 wiring and is intended for use across electrical, mechanical and electronics system environments.

Features and Benefits:

• IP66/IP67/IP69K rating provides protection in harsh environments
  PNP output enables easy integration with common control systems
  30VDC supply and 100mA current limit suits low-voltage applications
  Response time 2.5ms supports high-speed detection tasks
  Operating range -30 to 60°C allows use across temperature extremes
  Rectangular plastic housing simplifies panel and bracket mounting

Applications

• Suitable for conveyor object detection in automated lines
  Ideal for parts presence sensing in assembly stations
  Used for material handling checks in packaging machinery
  Can be used for safety monitoring of non-hazardous zones
  Used with PLC inputs requiring fast, Compact sensors

What connector type is used for wiring and installation?

The unit provides a 4-pin Terminal using an M12-style connector for quick field connection and standard sensor cabling.

How does the output type affect system wiring?

A sourcing PNP output switches the positive supply to the load, compatible with PLC inputs that expect a positive switching signal.

What approvals support use in regulated installations?

It carries UL-file approvals which confirm conformity to recognised safety assessment standards.

How does the light source influence maintenance cycles?

The LED emitter offers long operational life and stable illumination, reducing the need for frequent replacement compared with incandescent sources.
