Photoelectric sensors

G2S, Photoelectric proximity sensor, Background suppression

Type

GTB2S-P1311

Part No.

1064345

At a glance

Reliable detection of black and white objects at distances up to 15 mm

Background blanking from 18 mm

Laser-type light spot 2 mm in diameter at a distance of 8 mm

Your benefits

Faster machine cycles due to the brilliant, small light spots that allow accurate switching points and small gaps between objects

Universal use, since the sensors detect objects independent of their remission, object contours and backgrounds

High throughput and less downtime due to the sensor's ability to suppress active and passive interference in industrial environments.

The 45-degree tilted cable entry offers maximum installation flexibility with additional soft rubber bearings to absorb vibrations and tensile loads

The powerful PinPoint LED permits reliable detection of jet-black and poorly reflective objects
