The WTB27-3S1541 Sick Photoelectric Proximity Sensor is a SICK photoelectric sensor designed for object detection in industrial automation. It provides an adjustable 30 mm to 1,100 mm sensing range, uses a 660 nm visible red LED, supports a 20 V AC/DC to 250 V AC/DC supply, and provides a relay change-over output. The model belongs to the SICK photoelectric sensor series and uses background suppression for defined object detection.
The WTB27-3S1541 Sick Photoelectric Proximity Sensor can be used on conveyors, packaging machines, automated equipment, and assembly systems. Background suppression helps prevent unwanted detection from objects outside the intended sensing area, while the adjustable potentiometer allows the sensing distance to be set for the application. Its relay output provides electrically isolated switching, and the 2-meter PVC cable supports wired installation in industrial automation systems.
SICK WTB27-3S1541, Part No. 1027749, combines background suppression, adjustable sensing distance, visible red LED detection, and relay switching in an IP66-rated enclosure. The sensor also supports a wide AC/DC supply range and includes an integrated potentiometer for adjustment. As part of the SICK photoelectric sensor range, WTB27-3S1541 is suited to industrial conveyor, packaging, assembly, and automation applications requiring controlled object detection under demanding operating conditions.
