SICK GL10-R3711 Photoelectric Sensor – Complete Product Overview
Manufacturer: SICK AG
Series: G10
Part Number: 1065896
Sensor Type: Retro-reflective Photoelectric Sensor
1. Product Overview
The SICK GL10-R3711 is an industrial photoelectric sensor designed to detect objects without physical contact.
It works on the principle of light reflection. The sensor emits a visible red light beam towards a reflector. When an object interrupts the light beam, the sensor detects the object and changes its output signal.
This sensor is suitable for industrial automation, object detection, conveyor systems and machine monitoring.
Its sensing range can reach up to 15 metres when used with the specified PL80A reflector.
2. Key Features
The important features of the GL10-R3711 include:
Long Detection Range: Detects objects at distances up to 15 metres with a PL80A reflector.
PinPoint LED Technology: Provides a visible red light beam for accurate alignment.
Retro-reflective Technology: Detects objects by monitoring interruption of reflected light.
Dual Lens System: Designed with a minimum distance to the reflector.
Relay Output: Provides an electrically isolated SPDT switching output.
IP67 Protection: Protected against dust and temporary water immersion under specified test conditions.
Wide Voltage Range: Supports 24–240 V AC/DC.
Compact Design: Easy to install in industrial machinery.
3. Applications
SICK GL10-R3711 can be used in several industrial applications:
Conveyor Belt Systems: Detects products moving along conveyor belts.
Packaging Machines: Detects cartons, boxes and packages during automated packaging.
Material Handling: Monitors the movement of materials in industrial systems.
Automatic Doors: Detects objects passing through access barriers.
Production Lines: Helps monitor product presence and movement.
Industrial Automation: Provides object detection signals to control systems.
Machine Monitoring: Detects the presence or absence of objects during machine operation.
4. Why Choose SICK GL10-R3711?
There are several reasons to choose this sensor for industrial automation applications.
Non-contact Detection: No physical contact with the object is required.
Reliable Performance: Designed for consistent industrial object detection.
Long Sensing Distance: Suitable for applications requiring detection over longer distances.
Easy Integration: Relay output allows integration with compatible industrial control circuits.
Industrial Protection: IP67-rated housing helps protect the sensor in demanding environments.
Flexible Power Supply: Supports both AC and DC supply within its rated voltage range.
Reduced Mechanical Wear: Non-contact sensing avoids mechanical wear associated with physical switches.
