Industrial Through-beam Sensor
The Sick VS/VE18-4P3612 is a cylindrical through-beam photoelectric sensor designed for industrial automation and machine safety applications. 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 the L/D control cable. The sensor suits engineers and technicians who need reliable object detection over long distances in harsh environments.
20 Metre Maximum Range
The decisive specification is the maximum sensing range of 0 m to 20 m, with an operational sensing range of 0 m to 14 m. An infrared LED emits a beam with a 2.8° dispersion angle, creating a 700 mm light spot at 14 m. This range determines whether the sensor can bridge the required gap between emitter and receiver in your specific installation.
IP67 Sealed Housing
The plastic PBT/PC housing carries an IP67 enclosure rating, protecting the electronics from dust ingress and temporary water immersion during normal operation. Ambient operating temperature spans –25 °C to +70 °C. Power consumption is 30 mA with a 2 ms response time and 250 Hz switching frequency. The 2 m PVC cable with 0.14 mm² conductors carries four wires for power, output and test input functions.

Questions about this item
How far will the 20 m maximum sensing range actually reach in my setup?
The sensor detects objects reliably up to 14 m; the 20 m figure is the absolute maximum under ideal conditions.
What does the PNP output and 10–30 V DC supply mean for wiring?
The sensor sources current to the load, requiring a 10–30 V DC supply with ≤10 % ripple and a 4-wire cable connection.
Will the M18 × 1 thread and 63.6 mm body fit my existing bracket?
It mounts via an M18 × 1 thread, has a 63.6 mm cylindrical housing, 5 mm cable diameter and weighs 200 g.
