SICK Retroreflective Photoelectric Sensor, Barrel Sensor, 7.2 m, PNP, IP67

SICK GR18S Series Photoelectric Sensor, Pin Point LED Light Source, IP67 - GRL18S-P2336

This photoelectric sensor is a Compact retro‑reflective detection device designed for industrial automation and control environments. It uses a visible red pin‑point LED to detect objects against a reflector across short to medium distances, offering a sealed plastic enclosure suitable for installation where moisture or dust exposure is a concern. The sensor connects via a 3‑pin M12 connector and provides a PNP switching output for straightforward integration with control systems.

Features & Benefits

• High switching speed enables Rapid object detection at 1000Hz
  Fast response supports tight cycle times at less than or equal to 500μs
  Wide supply range accepts 10V–30V DC for flexible powering
  Protected enclosure delivers IP67 ingress resistance
  Output current capability supports loads up to 100mA
  Operating range covers 0.06m–6m with reflector PL80A

**Applications**

• Suitable for conveyor part detection in automated lines
  Ideal for presence sensing with reflective targets
  Used for material handling position feedback tasks
  Can be used for component counting in assembly stations
  Suitable for harsh factory environments requiring sealed sensors

What connector and mounting format does it provide?

It uses a straight M12 3‑pin connector and is designed for screw mounting into an M18x1 thread with supplied fastening nuts.

How does it indicate operating status and detection?

A green LED shows supply power
a yellow LED indicates received light‑beam status and object presence.

What temperature range can it operate in?

It operates between −25 °C to +55 °C and can be stored between −40°C to +70°C.

Which protections are implemented for electrical faults?

The device includes reverse‑polarity and overcurrent/short‑circuit protections depending on connection configuration and operating conditions.

What optical characteristics affect target detection?

It emits 650 nm red light with a light spot up to Ø175mm at 7m and uses a polarisation filter to reduce interference.
