Sick

Sick VS/VE18-4N3340 Through-beam Photoelectric Sensor NPN

SKU CH-CVJR-HHCHG

Through-beam photoelectric sensor with 20 m maximum range, NPN output, M18 metal housing and IP67 rating

  • Detects objects up to 20 m with through-beam infrared LED
  • 14 m reliable sensing range suits long-distance industrial applications
  • NPN output with selectable light/dark switching via control cable
  • IP67-rated nickel-plated brass housing withstands –25 °C to +70 °C
  • 250 Hz switching frequency and 2 ms response for fast detection

Through-beam sensor with 20 m range

The Sick VS/VE18-4N3340 is a cylindrical through-beam photoelectric sensor built for industrial detection tasks. Its metal housing measures 75 mm in length with an M18 x 1 thread for secure mounting. The unit operates on 10 V DC to 30 V DC supply voltage and connects via a 4-pin M12 male connector. An IP67 enclosure rating protects the sensor against dust and temporary water immersion.

Suited for automated lines needing fixed-range

This sensor suits production lines, packaging equipment and material-handling systems that require a consistent 14 m operating range with a 20 m maximum. The selectable light/dark switching via an L/D control cable allows one model to cover both output logic needs. Buyers who need adjustable sensitivity, teach-in alignment or background suppression should look at alternative sensor types that provide those functions.

NPN switching output with 100 mA capacity

The single specification that decides fit is the NPN switching output rated at a maximum of 100 mA output current. The controller or PLC input must accept NPN logic and stay within this current limit. A 2 ms response time and 250 Hz switching frequency support high-speed counting or positioning tasks. The infrared LED produces a 700 mm light spot at 14 m with an approximate 2.8° dispersion angle.

Questions about this item

Does the 250 Hz switching frequency cause noticeable heat during continuous operation?

Power consumption is 30 mA at 10–30 V DC, so heat output remains low even at the 250 Hz maximum switching frequency.

What voltage supply and connector must I already have to wire this sensor?

You need a 10–30 V DC source and a 4-pin M12 male connector to match the sensor's connection type.

Will the M18 × 1 thread and 75 mm housing fit the brackets I use for older M18 sensors?

Yes, the nickel-plated brass housing uses the standard M18 × 1 thread and 75 mm length common to many legacy M18 photoelectric sensors.
