SICK GTB6-P4212 1052442 G6 Miniature Photoelectric Sensor

SICK GTB6-P4212 is a miniature photoelectric proximity sensor with advanced background suppression for reliable object detection, independent of background colour. Part of the high‑performance G6 series, it emits a precise, highly visible PinPoint LED red light spot (650 nm, Ø 6 mm at 100 mm) for simple and robust setup. Housed in a compact 12 mm × 31.5 mm × 21 mm plastic body, the IP67‑rated sensor withstands demanding environments. It provides a PNP switching output (light‑on/dark‑on selectable via selector) with a 1,000 Hz switching frequency, making it suitable for high‑speed automation tasks in material handling, assembly, and packaging machinery.

Applications:

• High‑speed object detection by background suppression on conveyors (presence, positioning, counting)

• Small part detection in automated assembly and pick‑and‑place stations

• Bottle, container and product monitoring in packaging and labelling lines

• Material handling and sorting systems for logistics

• Reliable background‑independent detection even with differently coloured objects (e.g. black glass, shiny metal)

System Integration:

• This sensor belongs to the SICK G6 series of miniature photoelectric sensors.

• Designed for background suppression: reliably detects objects independent of their colour by ignoring the background beyond the set sensing range.

• The bright, precisely defined red PinPoint LED spot (650 nm, Ø 6 mm at 100 mm) simplifies alignment.

• Sensitivity can be fine‑tuned with a 5‑turn mechanical spindle.

• The transparent light/dark selector switch allows instant adaptation to the PLC input type without software.

• Mounting holes (one metal‑lined) conform to standard 1‑inch (25.4 mm) spacing for compatibility with all SICK mounting brackets.

• The M8 4‑pin male connector interfaces with standard industrial M8 female cables (e.g. YF8U14‑xxx pole).
