The SICK GTB6-P1231 (part no. 1074135) from the G6 series is a compact photoelectric reflex sensor with background suppression, engineered for reliable object detection in machine building, packaging lines and intralogistics. Its visible red PinPoint LED delivers a crisp, highly visible spot for precise alignment, while the rugged, block-style housing integrates easily into tight mounting spaces.

With a maximum sensing range of 5 to 400 mm (typical 50 to 220 mm), a fine 6 mm light spot at 100 mm and a 625 nm wavelength, it ensures stable detection even against complex backgrounds. The sensor switches at up to 500 Hz for high-throughput applications, offers selectable light/dark operation, and is quickly set via a 5-turn potentiometer. An industry-standard 3-wire PNP output and a 2 m integral cable streamline installation, while IP67 sealing, ABS/PC housing and an operating temperature of -25 to +55 °C support dependable use in harsh environments.

Choose the GTB6-P1231 to reduce false triggers, shorten commissioning and maintain process reliability across conveyors, feeders and small-parts handling, all while benefiting from proven SICK quality that is backed by a 1-year warranty.
