RS PRO Background Suppression Photoelectric Sensor, Block Sensor

Sick GTB6 Series Photoelectric Sensor, 100mA Maximum Current, IP67 - GTB6-P1212F38

This photoelectric sensor provides background suppression detection for automation and machine-vision tasks, using a visible LED to identify plastics and PMMA at short to mid ranges. It is a Compact block-style unit designed for bracket mounting in industrial environments, offering selectable light/dark switching and a mechanical sensitivity adjustment for accurate object discrimination.

Features & Benefits

• 35mm to 140mm sensing range for consistent object detection
  Response time 625μs for fast switching performance
  PNP output with up to 100mA sink capacity for direct device drive
  IP67 enclosure rating for protection in harsh environments
  10 to 30V DC supply allowing wide voltage compatibility
  Mechanical 5-turn adjustment for precise sensitivity setting

Applications

• Suitable for detecting polymethyl methacrylate components on conveyors
  Ideal for plastic part presence checks in assembly lines
  Used for short-range object discrimination in automated feeders
  Can be used for industrial packaging position verification
  Suitable for integration with PLC inputs requiring PNP signalling

What cable and connection format does it use?

It is supplied with a 2m, 3-core PVC cable configured for a PNP connection and 3-wire Interface wiring.

How is switching mode selected and indicated?

A rotary selector allows light or dark switching, and two LEDs show supply presence and received-light status.

What materials make up the housing and front window?

The housing combines ABS and polycarbonate while the front screen uses PMMA for optical clarity.

How is the sensor mounted and what is included?

It fits a bracket-mount arrangement and is supplied with a stainless-steel mounting bracket for installation.

What operating temperatures and storage limits apply?

Operating range is −25°C to +55°C with storage limits from −40°C to +70°C.
