SICK Background Suppression Photoelectric Sensor, Block Sensor, 5 mm → 400 mm, PNP, IP67

Sick Series G6 Photoelectric Sensor, IP67, 1250μs Response Time - GTB6-P4231

This photoelectric sensor is a Compact background-suppression device designed for industrial proximity detection where precise object discrimination is required. It operates from a DC supply and uses a visible red pin‑point LED to detect targets at short to medium ranges, making it suitable for integration into automated systems and machinery in industrial settings.

Features & Benefits

• IP67 enclosure protects electronics in wet or dusty conditions
  PNP output allows simple sourcing Interface with controllers
  Operates from 10VDC to 30VDC for versatile plant supply voltages
  Maximum output current 100mA supports direct drive of small loads
  Response time 1250μs enables Rapid detection in moving applications
  Mechanical sensitivity control offers on‑site adjustment flexibility

Applications

• Suitable for part‑present detection on assembly lines
  Ideal for separating objects against variable backgrounds
  Used for end‑of‑arm sensing on pick‑and‑place devices
  Can be used for conveyor monitoring where splash protection is needed

What connector type does it use for wiring?

It connects via a male M8 four‑pin connector for standard sensor cabling.

How is switching mode selected for different logic requirements?

A light/dark selector allows selection between light‑on and dark‑on switching modes.

What indicators assist with installation and diagnostics?

A green LED shows supply presence and a yellow LED indicates received light status.

What mounting method is provided for securing the sensor?

The unit mounts with screws using M3 fixing points designed for Compact installations.

What is the permitted ambient temperature range during operation?

It functions reliably between −25°C and +55°C when installed and adjusted within its stability limits.
