Cylindrical M18 nickel-plated brass photoelectric sensor with M12 connector

Sick

Sick VS/VE18-4P3140 Through-beam photoelectric sensor PNP

SKU CH-5BFC-H73G8

Through-beam photoelectric sensor with M18 cylindrical housing, 0–20 m sensing range, PNP output, M12 connector and IP67 rating

  • Reliable detection up to 20 m with through-beam infrared technology
  • Selectable light/dark switching via L/D control cable for flexible logic
  • Fast 250 Hz switching frequency suits high-speed automation
  • Rugged IP67-rated nickel-plated brass housing withstands harsh environments
  • Wide 10–30 V DC supply voltage simplifies integration

Industrial through-beam sensor for 14 m range

The SICK VS/VE18-4P3140 is a cylindrical M18 through-beam photoelectric sensor with a PNP switching output. It detects objects up to 14 metres using an infrared LED with a 2.8° dispersion angle. The metal nickel-plated brass housing measures 78 mm long and carries an IP67 enclosure rating. It operates on 10 to 30 V DC supply voltage.

Steady output at 250 Hz switching frequency

Under continuous operation the sensor maintains a 2 ms response time and a maximum switching frequency of 250 Hz. Power consumption stays at 30 mA with ripple limited to 10 %. The light/dark switching mode is selectable via the L/D control cable, and the test input can disable the sender by pulling TE to 0 V. Circuit protection covers supply polarity, short-circuit, overload and false-pulse suppression.

M12 connector eases wiring in tight spaces

Installation uses a 4-pin M12 male connector that fits standard industrial cordsets. The axial optical axis aligns with the barrel for straightforward mounting in M18 threaded holes. No potentiometer adjustment is required, reducing setup time. The 240 g weight and –25 °C to +70 °C temperature range suit panel and machine-frame mounting. UL file NMFT2.E175606 is on record.

Questions about this item

How much heat does the VS/VE18-4P3140 generate when running continuously on a 24 V supply?

The sensor draws 30 mA from a 10–30 V DC supply; at 24 V this is well under 1 W, so self-heating is minimal in an IP67 metal housing.

What power source and connector must I already have to operate this PNP sensor?

You need a 10–30 V DC supply and a 4-pin M12 female cable to match the male connector on the sensor.

Will the 2.8° infrared beam align easily with an older M18 reflector bracket I already use?

The sensor uses an M18 x 1 thread and axial optical axis, so it fits existing M18 mounts; the 2.8° dispersion gives a 700 mm spot at 14 m.
