SICK Background Suppression Photoelectric Sensor, Barrel Sensor, 3 mm → 300 mm, PNP, IP67

Sick GR18S Series Photoelectric Sensor, IP67, 100mA Maximum Current - GRTB18S-P2317

This photoelectric sensor is a cylindrical background suppression device designed for industrial automation. It detects objects across a selectable range using a visible red pin-point LED and is suited to installation where compact, thread-mounted sensors with robust ingress protection are required.

Features & Benefits

• Operating voltage 10V to 30V enabling flexible DC supply arrangements
  Output PNP with less than or equal to 100mA drive supporting direct actuator switching
  Response time less than 500μs allowing high-speed detection cycles
  IP67 enclosure rating permitting washdown and dusty environments
  Temperature range −25°C to +55°C maintaining performance in varied climates

Applications

• Suitable for conveyor object detection in packaging lines
  Ideal for presence sensing of parts on assembly fixtures
  used with robotic end-of-arm tools for pick-and-place confirmation
  Can be used for object counting in high-frequency sorting systems

How is the sensor connected electrically?

It uses a 3-pin M12 connector for straightforward plug-in wiring to control systems and cables.

What mounting method does it support?

Threaded M18 housing enables secure thread-mount installation with included fastening nuts for panel or bracket mounting.

How is sensing adjusted on-site?

A 270° potentiometer allows continuous adjustment of the detection range to suit target reflectivity and position.

What indicators show device status?

A green LED denotes power, while an amber LED signals object detection by the received light beam.

What electromagnetic and environmental protections are provided?

The unit meets EMC requirements and features plastic housing with PMMA optics Plus short-circuit and reverse-polarity protections in its circuitry.
