Cylindrical M18 plastic photoelectric sensor with 2 m PVC cable

Sick

Sick VS/VE18-4N3612 Through-beam photoelectric sensor NPN

SKU CH-R79X-K95FK

Through-beam photoelectric sensor detects objects up to 20 m with infrared LED, NPN output, IP67 housing, and 2 m PVC cable

  • Long detection reach up to 20 m range
  • Reliable switching at 250 Hz frequency
  • Secure NPN output handles 100 mA load
  • Rugged IP67 housing survives –25 °C to +70 °C
  • Ready-to-install 2 m PVC cable included

Sick Through-beam Sensor NPN Output

The Sick VS/VE18-4N3612 is a cylindrical through-beam photoelectric sensor designed for industrial detection tasks. It uses an infrared LED light source with an axial optical axis and offers a maximum sensing range of 0 m to 20 m. The housing features an M18 x 1 thread diameter and measures 63.6 mm in length. This NPN switching output sensor suits automation engineers and maintenance technicians.

Check Supply Voltage and Wiring

Verify that your control system provides a 10 V DC to 30 V DC supply with ripple below 10 percent. The sensor draws 30 mA and connects via a 2 m PVC cable with four 0.14 mm² conductors. Ensure the NPN output configuration matches your PLC input module and that the 100 mA maximum output current is sufficient for the load. The L/D control cable selects light or dark switching mode.

For Fixed-Range Presence Detection

This unit suits builders who need a pre-configured through-beam pair with a 14 m sensing range and 250 Hz switching frequency. It is not for buyers who want adjustable sensing distance or teach-in functionality. Users requiring AC supply voltage, PNP output logic, or a connector-based termination should look at something else. The IP67 enclosure suits harsh environments.

Questions about this item

Does the SICK VS/VE18-4N3612 include a receiver unit or must it be purchased separately?

The through-beam sensor consists of a separate sender and receiver; both units are required for operation and are supplied together in the package.

Which sensing range figure should I use when planning the installation — 14 m or 20 m?

Use the 14 m sensing range for reliable detection; the 20 m value is the absolute maximum under ideal conditions only.

What does the 250 Hz switching frequency mean for a production line moving at speed?

The sensor can change state up to 250 times per second, allowing it to detect objects spaced as little as 4 ms apart on a fast line.
