Sick GRL18S-N1331 M18 Cylindrical Photoelectric Sensor NPN 10-30V DC IP67

Sick GRL18S-N1331 M18 Cylindrical Sensor

The Sick GRL18S-N1331 is a cylindrical photoelectric retro-reflective sensor designed for industrial automation tasks. It uses a visible red PinPoint LED to detect objects at distances up to 7.2 metres with the PL80A reflector. The M18 metal housing carries an IP67 rating for harsh environments. This unit suits engineers and technicians specifying presence detection on conveyors or packaging lines.

Check Supply Voltage and Output Compatibility

Verify that your control system provides a 10 to 30 V DC supply within the specified ripple limits before wiring this sensor. The switching output is NPN light-switching with a maximum load of 100 mA, so the connected input must accept that logic type and current level. A 2-metre three-wire PVC cable is fitted; ensure the cable length and routing suit your cabinet layout. The operating temperature range spans –25 °C to +55 °C.

Ideal for Simple Retro-Reflective Detection

This sensor fits applications needing a robust M18 axial-beam device with no teach-in or potentiometer adjustment. It is not suited for installations requiring background suppression, polarised retro-reflection for shiny targets, or faster response times below 500 microseconds. Buyers who need a different sensing principle, connector termination, or higher switching frequency should look at alternative models.
