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-P5211

This miniature photoelectric sensor detects objects using background suppression and is designed for industrial automation tasks. It operates on a DC supply and provides a PNP switching output, making it suitable for integration into control systems where compact, panel-mounted proximity sensing with visible red light detection is required.

Features & Benefits

• Background suppression up to 250mm enables accurate object detection
  Visible pin-point LED at 650 nm delivers precise beam localisation
  Fast response time of 625 μs supports high-speed switching
  Output current up to 100 mA allows direct drive of control inputs
  Wide supply range 10V to 30V accommodates varied DC systems
  IP67-rated plastic housing permits use in wash-down or dusty environments

Applications

• Suitable for part detection on high-speed assembly lines using background suppression
  Ideal for integration with PLC inputs requiring PNP switching behaviour
  Used for distance-limited object presence checks where a precise beam spot is needed
  Can be used for machine Vision triggering when compact, panel-mounted sensors are preferred

What connector arrangement does it use for wiring?

It terminates in an M8 3-pin connector with a 300mm cable tail for straightforward connection to sensor to actuator wiring.

How does temperature affect operation after adjustment?

The device maintains stability within ±10 °C of the setpoint
the rated operating temperature range is -25 °C to +55 °C.

What protection functions are included for electrical faults?

The outputs include overcurrent and short-circuit protection Plus reverse-polarity safeguarding on supply and I/O connections.

How adjustable is the sensing behaviour?

Sensitivity is set via a five-turn mechanical spindle and a rotary light/dark switch for selecting the switching mode.
