The WL27-3R2631 Sick Photoelectric Proximity Sensor is a SICK retro-reflective photoelectric sensor for object detection in industrial automation. It provides a 0.1 m to 15 m sensing range, uses a visible red LED, supports a 20 V AC/DC to 250 V AC/DC supply, and provides an SPDT relay change-over output. The WL27-3R2631 belongs to the SICK W27 series and includes a dual-lens system, Q6 connector, potentiometer adjustment, and integrated timing functions.
The WL27-3R2631 Sick Photoelectric Proximity Sensor can be used on conveyors, packaging machinery, automated production equipment, and assembly systems. Its retro-reflective operating principle supports object detection across longer sensing distances, while the electrically isolated relay output provides switching for industrial control circuits. The adjustable potentiometer helps tune sensor operation, and integrated switch-on, switch-off, and adjustable time delays provide additional control when coordinating detection with automated machine sequences.
SICK WL27-3R2631, Part No. 1027776, combines long-range retro-reflective detection, relay switching, universal AC/DC supply, and a Q6 6-pin connection. Its ABS housing carries an IP65 rating and is specified for environments involving vibration, shock, and temperature variation. As a SICK W27 series photoelectric sensor, this model is suitable for conveyor, packaging, assembly, and general industrial automation applications requiring adjustable sensing and electrically isolated relay switching.
