Sick

Sick VS/VE18-3P3240 Through-beam photoelectric sensor PNP

SKU CH-HY19-JM442

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

  • Detects objects up to 20 m away with infrared through-beam technology
  • Adjustable sensitivity via 270° potentiometer for precise detection tuning
  • Fast 250 Hz switching frequency enables high-speed counting applications
  • Rugged IP67-rated nickel-plated brass housing withstands harsh environments
  • Operates reliably from –25 °C to +70 °C across industrial temperature ranges

Through-beam sensor for 20 m range

The Sick VS/VE18-3P3240 is a cylindrical through-beam photoelectric sensor designed for industrial detection tasks. It uses an infrared LED with a maximum sensing range of 0 m to 20 m and a defined sensing range of 0 m to 14 m. The axial optical axis and 2.8° dispersion angle create a 700 mm light spot at the maximum defined distance. Sensitivity is adjustable via a 270° potentiometer.

M18 metal housing with M12 connector

The nickel-plated brass housing measures 78 mm in length with an M18 x 1 thread for secure mounting. An M12 4-pin male connector provides the electrical interface, while the IP67 enclosure rating protects against dust and temporary immersion. Weighing 240 g, the unit operates on 10 V DC to 30 V DC with a 30 mA power consumption and includes circuit protection categories A through D.

PNP dark-switching output at 250 Hz

The sensor delivers a PNP dark-switching output rated at 100 mA maximum current with a 2 ms response time and 250 Hz switching frequency. A test input allows the sender to be switched off by connecting TE to 0 V. The operating temperature spans –25 °C to +70 °C, and the LED light source offers an average service life of 100,000 hours at 25 °C. UL file NMFT2.E175606 is listed.

Questions about this item

What sensing range does the M18 through-beam sensor deliver in practice?

The sensor detects objects from 0 m to 14 m with a maximum range of 20 m using infrared light.

What mounting dimensions and clearance does the cylindrical M18 housing require?

The nickel-plated brass barrel is 78 mm long with an M18 x 1 thread and an axial optical axis.

How do I wire the 4-pin M12 connector and set the PNP dark-switching output correctly?

Connect the male M12 plug to 10–30 V DC; the PNP output switches dark at 100 mA max with 2 ms response.
