SICK VL18-4P3240 Retroreflective Photoelectric Sensor

The SICK VL18-4P3240 is a cylindrical retroreflective photoelectric sensor that houses both emitter and receiver in a compact 18 mm-diameter, 78 mm-long body (M18 x 1 thread) with an axial optical axis. Built to endure tough environments, it carries an IP67 enclosure rating and uses a LED light source for reliable reflection-based sensing. It detects retroreflective targets from 0.5 m up to 3.7 m, making it suitable for presence sensing on conveyors, packaging lines, and automated equipment where a compact footprint is advantageous. The VL18-4P3240 is part of SICK's VL18 family, providing a single-head retroreflective solution for straightforward object detection on industrial assemblies.
