SICK GTB6-P4211 1052438 Photoelectric Proximity Sensor PNP 250mm IP67

SICK GTB6-P4211 is a miniature photoelectric proximity sensor from the G6 series with background suppression for reliable object detection independent of background colour. Its PinPoint LED technology creates a bright, precisely defined visible red light spot (650 nm wavelength) for easy sensor alignment. Housed in a compact 12 mm × 31.5 mm × 21 mm plastic (ABS/PC) body rated IP67, it is suitable for high-speed automation tasks in material handling, packaging, and assembly lines.

Applications:

• High-speed conveyor object presence and positioning

• Packaging machinery for product sorting, counting, and quality control

• Automated assembly lines for part detection and pick-and-place stations

• Electronics industry for small component detection positioning
