SICK VL18-4N3312 retro-reflective sensor

The SICK VL18-4N3312 is a cylindrical photoelectric retro-reflective sensor with an angled light emission design. It operates on a 10 V DC to 30 V DC supply voltage with a visible red LED light source. The sensor provides an NPN switching output with selectable light or dark switching via an L/D control cable. A 2 m PVC cable with a 0.14 mm² conductor cross-section handles the connection.

Suited for presence detection up to 3.7 m

This sensor suits applications needing object detection within a 0.05 m to 3.7 m sensing range using a reflector. The IP67 enclosure rating and brass nickel-plated metal housing support use in harsh industrial environments. Buyers needing a diffuse or through-beam detection principle should look at other sensor types. The fixed 2 ms response time may not suit high-speed counting or positioning tasks requiring faster switching.

Check supply voltage and wiring compatibility

Verify that your control system provides a 10 V DC to 30 V DC supply with ripple below 10 % and can accept an NPN switching signal. Confirm the 2 m cable length and Ø 5 mm diameter suit your routing and termination requirements. Ensure the operating temperature range of –25 °C to +70 °C covers the installation environment. The potentiometer adjustment allows range tuning after mounting.

Questions about this item

What supply voltage must my system provide for the VL18-4N3312 sensor?

The sensor operates on 10 V DC to 30 V DC with a maximum ripple of 10 %.

Will the 2 m PVC cable and NPN output work with my existing PLC input card?

The unit has a 2 m PVC cable, 0.14 mm² conductors and an NPN light/dark switching output selectable via the L/D control wire.

How can I verify the sensor is detecting correctly after mounting?

The visible red LED light spot and the 2 ms response time let you see alignment and confirm switching action in real time.
