SICK Retroreflective Photoelectric Sensor, Block Sensor, 5 m, PNP, IP66, IP67, IP68, IP69K

SICK Series W4 Photoelectric Sensor, Stainless Steel Housing, IP66/IP67/IP68/IP69K - WLG4S-3F2235V

This photoelectric sensor is a Compact detection device designed for retro-reflective sensing of transparent objects in industrial environments. Housed in stainless steel, it connects via a 4-pin M8 Interface and outputs a PNP signal for straightforward integration with control systems.

Features and Benefits:

• Pin point LED offers precise detection of clear materials
  IP66 IP67 IP68 IP69K rating enables use in washdown conditions
  30V DC supply compatibility supports common control voltages
  100 mA maximum current allows direct drive of modest loads
  500 μs response time delivers Rapid object recognition
  Rated to operate between −30 °C and 60 °C for varied environments

Applications

• Suitable for conveyor-line separation of clear packaging
  Ideal for machine Vision trigger of transparent parts
  Used with PLC inputs in automated assembly stations
  Can be used for level sensing of clear liquids in containers

What connector and wiring format does it use for installation?

It uses a four-pin M8 connector with a four-terminal Interface for straightforward wiring to industrial control equipment.

How is the sensor mounted to machinery?

The unit accepts threaded and through-hole mounting methods to accommodate fixed, secure installation in tight spaces.

What output behaviour should be expected when a target is detected?

The device provides a PNP switching output compatible with positive-supply input circuitry and standard PLC sensors.

Are there any recognised approvals relevant to electrical safety testing?

It carries specific UL file references indicating conformity with established assessment records for electrical products.
