The WTB27-3S1511 Sick Photoelectric Proximity Sensor is designed for object detection in industrial automation. It provides a 100 mm to 1,600 mm sensing range, background suppression, an 880 nm infrared LED, and a 20V AC/DC to 250V AC/DC supply range. The sensor belongs to the SICK photoelectric sensor series and uses a relay output for electrical isolation.
The WTB27-3S1511 Sick Photoelectric Proximity Sensor can be used for object detection on conveyors, packaging equipment, automated machinery, and assembly systems. Background suppression helps distinguish the target object from reflective backgrounds, while the adjustable sensing range allows the detection distance to be set using the potentiometer. Its relay output and wide AC/DC supply range support integration into different industrial automation applications.
SICK WTB27-3S1511, Part No. 1027762, is a rectangular photoelectric proximity sensor intended for industrial object detection. The sensor combines adjustable sensing distance, infrared LED detection, background suppression, and relay output in a 24.6 mm × 80.6 mm × 54 mm housing. These supplied specifications make the WTB27-3S1511 suitable for conveyor, packaging, assembly, and general automation applications requiring consistent object detection.
