Compact Retro-reflective Sensor
The Sick WL8-P1131S07 is a photoelectric retro-reflective sensor with autocollimation designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply and provides a PNP switching output with selectable light or dark switching via a rotary switch. The sensor suits automation engineers needing reliable object detection in tight spaces.
IP67 Housing with Tyco Connector
The rectangular plastic housing measures 11 mm by 31 mm by 20 mm and carries an IP67 enclosure rating for dust and water protection. A 990 mm PVC cable terminates in a Tyco connector, simplifying installation in control cabinets or on machine frames. The visible red LED emits a 650 nm beam with a 30 mm spot at 1 m distance.
Upgrade for High-speed Lines
This unit replaces slower or larger sensors where a 2,000 Hz switching frequency and 0.25 ms response time are required to detect objects moving at high speeds. The sensing range extends to 4 m maximum, with a practical range up to 3 m. The jump is worthwhile when cycle times demand sub-millisecond response and a compact footprint.
