SICK GTB6-P4211 1052438 Photoelectric Proximity Sensor PNP

SICK GTB6-P4211 is a miniature photoelectric proximity sensor with background suppression from the G6 series. Using PinPoint LED technology (visible red light, 650 nm wavelength) with a precise Ø6 mm light spot at 100 mm, it reliably detects objects from 5 mm to 250 mm maximum. Equipped with a PNP output switchable between light‑on and dark‑on through an onboard selector, an M8 4-pin male connector for electrical interface, and an IP67 housing, this sensor is suitable for factory automation, material handling, and packaging applications.

Applications:

• Automated production lines and assembly systems

• Material handling and conveyor systems for object presence detection

• Quality control stations in manufacturing

• Packaging, printing, and bottling machinery

• Process automation and logistics applications
