Sick GTB6 Series Photoelectric Sensor, 30V Maximum DC Voltage, IP67 - GTB6-P4212F38

This photoelectric sensor is a background‑suppression proximity device designed for industrial sensing in automation and control environments. It uses a visible LED light source to discriminate objects against their backgrounds over a practical working distance, while a rugged plastic enclosure and M8 connector support easy integration into machines and production lines.

Features & Benefits

• Background suppression improves target detection accuracy for variable surfaces
  35mm to 140mm sensing range matches short‑ to mid‑distance tasks
  PNP output supports direct interfacing with common control inputs
  IP67 rating enables temporary immersion and wash‑down compatibility
  625 μs response time allows high‑speed switching in fast processes
  10V to 30V DC supply permits flexible plant power connection

Applications

• Suitable for object presence detection on conveyor lines
  Ideal for part orientation checks in pick‑and‑place stations
  Used for material sorting where background contrast varies
  Can be used for machine guard sensing with Compact mounting
  Suitable for feeder and hopper monitoring in assembly systems

How is the sensor adjusted for different target reflectivities?

It features a five‑turn mechanical sensitivity control and a light/dark selector to tune switching behaviour for various reflectances.

What electrical protections are provided for plant safety?

The device includes reverse‑polarity protection on supply and I/O and overcurrent/short‑circuit protection on outputs as specified for the circuitry.

Which connector and mounting accessories are supplied?

A male M8 4‑pin connector is fitted and a stainless‑steel mounting bracket (1.4301/304) is included for bracket installation.

How does ambient temperature affect performance after setup?

The sensor maintains stability within ±10 °C of the adjusted temperature and operates from −25 °C to +55 °C with storage to −40 °C/+70 °C.

What indicators show operational status during commissioning?

A green LED signals supply presence and a yellow LED indicates received light‑beam status for alignment and diagnostics.
