SICK VL18-3F3912 Retro-Reflective Sensor

The SICK VL18-3F3912 is a photoelectric retro-reflective sensor designed for industrial detection tasks. It operates on a 10 V DC to 30 V DC supply with a PNP light-switching output. The visible red LED light source provides a sensing range up to 3.7 m. This device suits automation engineers and electricians integrating presence detection into machinery or conveyor systems.

Cylindrical Angled Housing IP67 Rating

The sensor features a cylindrical, angled housing measuring 60.6 mm with plastic housing and PMMA optics. An IP67 enclosure rating protects against dust ingress and temporary water immersion. A fixed 2 m PVC cable with 0.14 mm² conductors and 3.1 mm diameter simplifies wiring without separate connectors. The potentiometer adjustment allows on-site sensitivity tuning for varying target reflectivity.

Check Supply Voltage Cable Length Mounting

Verify that your control system provides a stable 10 V DC to 30 V DC supply within the 10 % ripple limit. Ensure the 2 m cable length reaches your termination point without splices. Confirm the cylindrical angled form factor fits the available mounting space and that the 2.8° dispersion angle suits the target distance. The operating temperature range spans –25 °C to +70 °C.
