Cylindrical M18 nickel-plated brass sensor, 75 mm long, radial optical axis, M12 4-pin connector

Sick

Sick VS/VE18-3P3340 Through-beam photoelectric sensor PNP

SKU CH-4F9Z-74WJR

A through-beam photoelectric sensor with 20 m maximum range, PNP dark-switching output, M12 connector and IP67-rated metal housing

  • Through-beam sensing up to 20 m range
  • Infrared LED with 2.8° dispersion angle
  • PNP dark-switching output at 250 Hz
  • M12 4-pin connector for quick wiring
  • IP67 nickel-plated brass housing, –25 °C to +70 °C

Industrial detection sensor

The Sick VS/VE18-3P3340 is a cylindrical through-beam photoelectric sensor built for industrial automation. It uses an infrared LED to detect objects across distances up to 20 metres. The M18 nickel-plated brass housing carries an IP67 rating for harsh environments.

Suits fixed-range monitoring

This unit fits machines needing a set 14-metre sensing range with dark-switching PNP output. It is not for applications that require adjustable sensitivity, teach-in alignment, or background suppression modes. Buyers needing variable detection zones should consider other sensing principles.

10 to 30 volt DC supply

The sensor operates on a 10 V DC to 30 V DC supply with a 30 mA power draw. It connects via a 4-pin M12 male connector and switches at 250 Hz. Verify your control voltage matches this range before installation.

Questions about this item

Will the M18×1 threaded housing fit the mounting brackets I already use for 18 mm sensors?

The sensor uses an M18×1 thread diameter, so it matches standard 18 mm brackets and nuts.

How can I verify the PNP dark-switching output is functioning after wiring it to a 24 V DC supply?

Apply 10–30 V DC, align sender and receiver, then block the beam; the output should switch high within 2 ms and the indicator LED will change state.

Does the package include the M12 4-pin connector cable or must I order it separately?

The sensor has a male M12 4-pin connector; a compatible cable assembly is not included and must be purchased separately.
