SICK Energetic Photoelectric Sensor, Barrel Sensor, 5 mm → 550 mm, PNP, IP67

Sick GR18S Series Photoelectric Sensor, 1ms Response Time, IP67 - GRTE18S-P2347

This photo‑electric sensor is a Compact cylindrical proximity device designed for object detection in industrial automation. It operates using an Active photo‑electric principle with visible red pin‑point LED illumination, suitable for inline sensing tasks where a robust, sealed sensor is required.

Features & Benefits

• IP67 enclosure rating for wet and dusty environments
  PNP switching output allowing direct sourcing to control inputs
  10V DC to 30V DC supply for common industrial voltages
  Less than or equal to 100 mA output current supporting typical input loads
  Less than 1 MS response time for fast detection and high cycle rates
  Potentiometer sensitivity adjustment for on‑site tuning

Applications

• Suitable for conveyor object presence detection in packaging lines
  Ideal for short‑ to long‑range part detection in assembly cells
  Used for presence monitoring of reflective or painted surfaces
  Can be used for automated gating and product counting systems
  Suitable for integration with PLC inputs in control panels

What connection type does it use for wiring?

It connects via an M12 3‑pin connector and is supplied with fastening nuts for simple thread mounting.

How does the sensor indicate switching and power status?

A green LED shows power on while a yellow LED indicates received light and object presence.

What temperature range can it operate within?

It is rated to function between −25 °C and +55 °C for typical industrial ambient conditions.

What optical performance can be expected on different reflectances?

With a 650 nm light source and Ø9mm spot at 400 mm, sensing range varies by object reflectance up to 550mm on high‑reflectance targets.

How is the sensing range adjusted on site?

A 270° potentiometer allows precise sensitivity setting to suit varying target sizes and reflectivities.
