Sick

Sick VS/VE18-4P3240 Through-beam photoelectric sensor PNP

SKU CH-58GN-HKSPF

A through-beam photoelectric sensor detecting objects up to 20 m with a PNP output and M12 connector

  • Detects objects up to 20 m away with through-beam infrared sensing
  • Selectable light or dark switching via L/D control cable for flexible logic
  • Fast 250 Hz switching frequency enables rapid response in automation
  • Rugged IP67 nickel-plated brass housing withstands harsh industrial environments
  • Operates reliably from –25 °C to +70 °C across wide temperature range

Through-beam photoelectric sensor PNP

The Sick VS/VE18-4P3240 is a through-beam photoelectric sensor with a PNP switching output. It uses an infrared LED light source and a cylindrical metal housing with an M18 x 1 thread. The unit operates on a 10 V DC to 30 V DC supply voltage and offers an IP67 enclosure rating for industrial environments. It is suited for automation tasks requiring reliable object detection.

M18 cylindrical housing with M12 connector

The sensor fits into an M18 threaded mounting point and connects via a male M12, 4-pin connector. Its axial optical axis aligns with the housing for straightforward installation. A selectable light/dark switching mode via the L/D control cable adapts the output logic to the control system. Circuit protection covers supply and output faults, while a test input allows the sender to be disabled for diagnostics.

20 m maximum sensing range

The device achieves a maximum sensing range of 0 m to 20 m and a defined sensing range of 0 m to 14 m with a 700 mm light spot at that distance. Sensitivity is adjustable through a 270° potentiometer. Switching frequency reaches 250 Hz with a 2 ms response time and a 100 mA output current limit. Operation is rated from –25 °C to +70 °C. Builds needing longer range or different output types must look elsewhere.

Questions about this item

What is the maximum sensing range before the sensor loses detection under continuous operation?

The through-beam sensor reaches a maximum sensing range of 20 metres, with a defined sensing range up to 14 metres using infrared LED light.

How much heat or power does the unit draw when running all day on a 24 V supply?

Power consumption is 30 mA at 10 to 30 V DC with 10 % ripple, and the housing is rated IP67 for ambient temperatures from –25 °C to +70 °C.

Which connector and voltage must my control cabinet already provide for this PNP sensor to work?

It requires a 4-pin M12 male connector and a 10 to 30 V DC supply with PNP switching output up to 100 mA.
