SICK Background Suppression Photoelectric Sensor, Block Sensor, 5 mm → 250 mm, PNP, IP67

Sick Series G6 Photoelectric Sensor, 30V Maximum DC Voltage, 100mA Maximum Current - GTB6-P1211

This photoelectric sensor is a Compact background suppression proximity device intended for industrial automation tasks. It detects objects using a visible red LED beam and is designed for installation where sealed operation and selectable light/dark switching are required. The sensor is suitable for panel mounting and connects via a three-pin M8 interface.

Features & Benefits

• Background suppression delivers reliable object detection up to 140 mm
  PNP output supports direct interfacing with common control systeMS
  IP67 enclosure enables operation in dusty and water‑exposed environments
  Fast response time of 0.625 MS allows high‑speed switching at 1000 Hz
  Maximum current handling of 100 mA permits use with typical loads
  Operating range from −25 to +55 °C accommodates factory ambient conditions

Applications

• Suitable for conveyor object presence detection with background suppression
  Ideal for part counting in high‑frequency production lines
  Used for proximity monitoring where sealed sensors are required
  Can be used for simple machine interlocks requiring PNP switching
  Suitable for integration into control panels using M8 three‑pin connections

How is sensitivity adjusted on the device?

Sensitivity is set via a five‑turn mechanical spindle on the housing for precise tuning.

What light characteristics does it use for detection?

It emits visible red light at about 650 nm with a pinpoint LED spot approximately 6mm at 100 mm.

What cable and connector arrangement is supplied?

The unit is fitted with a 2 m PVC cable wired for three conductors and terminated for an M8 connection.

How does the sensor protect against electrical faults?

The electronics include reverse‑polarity and short‑circuit protection for inputs and outputs, and an overcurrent safeguard.

What installation considerations apply to the housing material?

The body is MADE from a polycarbonate/ABS blend with a PMMA front, so avoid exposure to solvents that may affect the plastics.
