SICK Retroreflective Photoelectric Sensor, Rectangular Sensor

SICK Series G6 Photoelectric Sensor, IP67, 30V DC Maximum DC Voltage - GL6-N4211

This photoelectric sensor detects objects using a retro‑reflective optical arrangement and is designed for use in industrial automation and control systems. It is built in a Compact rectangular form with a robust ABS plastic enclosure and connects via a 4‑pin M8 interface. The device operates from low‑voltage DC supplies and delivers switching information through an NPN output suitable for integration with typical control hardware.

Features and Benefits:

• Pin‑point LED light source enables precise target sensing
  Response time 625 μs supports high‑speed detection tasks
  IP67 ingress protection permits wash‑down and dusty environments
  Operating temperature range −25 to 55 °C suits varied processes
  Maximum supply 30V DC allows safe low‑voltage system integration
  Maximum current 100 mA minimises load on control circuits

Applications

• Suitable for object presence detection on conveyor lines
  Ideal for parts counting in assembly automation
  Used for edge detection in packaging machinery
  Can be used for material‑handling position verification
  Suitable for integration with PLC inputs in production cells

What electrical connection does it use for installation?

It employs a 4‑pin M8 connector providing a Compact Interface for power and signal wiring.

How does the output Interface with control equipment?

The sensor uses an NPN output type that switches to common/earth when activated for sinking input circuits.

What environmental conditions can it withstand during operation?

The unit is rated to IP67, protecting against dust ingress and temporary immersion for harsh plant conditions.

Are there approvals that support its use in standard industrial installations?

It carries UL file references NRKH.E348498 and NRKH7.E348498 which relate to recognised safety standards.
