SICK Retroreflective Photoelectric Sensor, Rectangular Sensor

Sick G10 Series Photoelectric Sensor, IP67, 1ms Response Time - GL10G-P4251

This photoelectric sensor is a Compact retro-reflective detector designed for industrial automation tasks where reliable object sensing is required. It operates on a DC supply and uses a focused visible red LED to detect targets via a reflector, providing Rapid switching for conveyor, material handling and machine-safety installations. The device is built for panel mounting in challenging environments and connects via a 4-pin M12 interface.

Features & Benefits

• 10V to 30V DC supply supports common control voltages and drives
  ≤1ms response enables high-speed detection on fast lines
  PNP output with ≤100mA drive suits direct actuator control
  IP67 enclosure rating permits washdown and dust-prone areas
  Visible 625nm PinPoint LED gives precise alignment at distance
  Operating range to 12m with reflector PL80A for long reach

Applications

• Suitable for presence detection on high-speed conveyors
  Ideal for transparent object detection in packaging lines
  Used for part verification before robotic pick-and-place
  Can be used for end-of-line pallet detection with reflectors
  Suitable for integration into machine control panels

What connector and wiring does it use for installation?

It uses a male M12 4-pin connector with standard wiring for power, output and reference
one pin remains unused in the diagram.

How does the sensor handle electrical disturbances on the supply?

It includes reverse-polarity protection and interference-suppression circuitry to maintain stable switching under typical industrial noise.

What temperature range can it operate within on-site?

It functions reliably between −30°C and +60°C for normal industrial ambient conditions.

How is switching behaviour selected for different detection tasks?

A local light/dark switching selector lets you choose detection mode without external wiring changes.

What indicators are provided to aid commissioning?

Front LEDs show power status and received light-beam status to simplify alignment and troubleshooting.
