SICK Background Suppression Photoelectric Sensor Block Style, Relay Output, 20 mm to 950 mm Detection Range GTB10-R3812

SICK GTB10-R3812 Background Suppression Photoelectric Sensor is a block-style photoelectric sensor featuring a detection range from 20 mm up to 950 mm and a relay SPDT output switch designed for industrial automation and control tasks. Operating at 24V to 240V AC/DC, this sensor uses a visible red LED light source that ensures accurate presence or absence detection by background suppression.

Its IP67 rated housing is built from a combination of plastic, polymethyl methacrylate, and polyvinyl chloride, providing excellent durability and electrical insulation in dust-tight and water-prone environments.

The GTB10-R3812 relay output supports electrically isolated switching currents up to 3 amperes, while its fast 10 ms response time facilitates moderate-speed detection cycles. A potentiometer allows precise adjustment of sensing range with five turns, enhancing accuracy across various surfaces and reflectances. LED status indicators provide power and received beam feedback to ensure operational insight.

This sensor is ideal for material handling presence detection on conveyors, pick-and-place system background suppression, door or gate monitoring requiring isolated relay switching, and object counting on packaging machinery with varying reflectance. Its rugged performance suits industrial, manufacturing, and automation applications demanding reliable object detection to improve process control.

The sensor operates effectively within temperatures from -30°C to +60°C and may be stored between -40°C and +70°C. It is built to perform at a minimum of 100,000 switching cycles at rated loads, offering excellent switching endurance for long-term industrial use.

Operates with a visible red LED light source for precise object detection. Relay SPDT output provides electrically isolated switching up to 3A capacity. Designed for panel mounting with a 2m five-core PVC cable for direct connection.

Robust IP67 rated enclosure ensures dust-tight and water-exposed zone use. Potentiometer adjustment allows precise five-turn range setting. Response time of 10 milliseconds supports medium-speed detection cycles. Suitable for presence detection on conveyor lines and pick-and-place systems.

Constructed with durable plastic, polymethyl methacrylate, and polyvinyl chloride housing materials. Operates reliably between -30°C and +60°C for various industrial environments. Made in Malaysia for quality industrial sensor applications.
