Sick GR18S Series Photoelectric Sensor, 100mA Maximum Current, IP67 - GRL18S-P2431

This photoelectric sensor is a retroreflective, cylindrical device designed for industrial automation tasks where non-contact object detection is required. It emits visible red light and monitors a returned beam via a reflector, offering compact, threaded housing and a 4-pin M12 connector for straightforward integration in control systems.

Features & Benefits

• Visible red LED ensures clear detection at long range
• Response time 0.5 MS supports fast switching operations
• PNP output allows direct sourcing to PLC inputs
• IP67 enclosure permits use in wet or dusty environments
• Supply range 10V to 30V DC accommodates varied control voltages
• Output current up to 100 mA enables direct drive of small loads

Applications

• Suitable for part presence detection on conveyor systems
• Ideal for web edge monitoring with retroreflective targets
• Used for object counting in packaging machinery
• Can be used for safety interlocks requiring non-contact sensing
• Suitable for inspection stations using reflective tape markers

What connector and wiring format does it use?

It employs a male M12, 4-pin connector with standard wiring for sensor to actuator interfaces.

How does it indicate operating status and detection?

Two LEDs provide status: a green LED for power and a yellow LED that shows received-beam condition.

What environmental temperatures can it operate within?

It functions across an ambient range from −25 °C to +55 °C for normal operation and can be stored between −40 °C and +70 °C.

What protection and materials are used for harsh conditions?

The housing combines metal, nickel-plated brass and ABS, and the unit meets IP67 ingress protection for dust and temporary immersion.

Which light characteristics define its sensing performance?

It emits 650 nm visible light from a PinPoint LED with a measured spot size appropriate for reflector-based detection at several metres.
