Product Name: SICK GL10-R3811

Brand: SICK

Product Type: Photoelectric Retro-reflective Sensor

Part Number: 1064689

Series: G10

1. Product Overview

The SICK GL10-R3811 is an industrial photoelectric retro-reflective sensor designed for reliable, non-contact object detection in automation systems.

It works by transmitting visible red light towards a reflector and receiving the reflected light back. When an object interrupts the light beam, the sensor detects its presence and changes its output signal.

This sensor features a dual-lens optical system, a long sensing range and a relay switching output. It is suitable for conveyor systems, packaging machines, manufacturing plants and material-handling applications.

The sensor can operate with AC/DC power supplies, making it suitable for different industrial control environments.

2. Key Features

The main features of the SICK GL10-R3811 include:

  • Long Sensing Range: Maximum sensing distance of up to 15 metres with a PL80A reflector.

  • Retro-reflective Technology: Detects objects using a reflector.

  • Dual Lens System: Provides reliable optical detection with a minimum reflector distance.

  • PinPoint LED: Produces a bright and precise visible red light spot.

  • Relay Output: Features an electrically isolated SPDT relay switching output.

  • Wide Power Supply: Supports 24–240 V AC/DC.

  • Sensitivity Adjustment: Includes a 270° potentiometer for adjustment.

  • Compact Design: Small rectangular housing for easy installation.

  • IP67 Protection: Provides protection against dust and temporary water immersion.

  • Ambient Light Immunity: Designed for reliable operation despite optical interference.

3. Applications
