SICK Retroreflective Photoelectric Sensor, Rectangular Sensor, 5 m, PNP, IP66, IP67, IP69K

SICK Series W9 Photoelectric Sensor, IP66/IP67/IP69K, P inches Point LED Light Source - WL9G-3P2432

This photoelectric sensor is a Compact retro‑reflective detector designed for industrial automation and process control. It detects transparent objects with a focused light source and connects via a standard M12 interface, making it suitable for integration into conveyor, packaging and inspection systems where precise optical detection of clear items is required.

Features and Benefits:

• Pin‑point LED for precise transparent object detection
  500 μs response time enabling fast cycle integration
  PNP output for direct interfacing with PLC inputs
  IP66, IP67 and IP69K protection for aggressive wash‑down environments
  30V DC maximum supply supporting common control voltages
  100 mA maximum current allowing connection to typical loads

Applications

• Suitable for clear‑bottle detection on bottling lines
  Ideal for label presence checks on transparent film
  Used for part‑present sensing on high‑speed conveyors
  Can be used for inspection of sealed transparent packaging
  Suitable for machine‑vision pre‑triggering in automation cells

What connector type does it use for wiring?

It uses a 4‑pin M12 connector enabling quick, keyed field connections and straightforward cabling to control equipment.

What temperature range can it operate within?

It functions across −40 °C to 60 °C allowing use in cold storage and warm industrial environments.

How is the unit mounted in machinery?

The sensor is designed for hole mounting to provide secure fastening in fixed installations.

Which approval allows use in standard North American installations?

It carries UL file approval NRKH.E181493 indicating acceptance under applicable UL criteria.

What detection arrangement does it employ for reflective sensing?

The device operates as a retro‑reflective unit, using a reflector to return the emitted beam for object interruption detection.
