Cylindrical M18 nickel-plated brass sensor with M12 connector

Sick

Sick VTE18-4P2140 photoelectric proximity sensor PNP

SKU CH-78J8-0V7XG

Photoelectric proximity sensor with 3 mm to 200 mm sensing range, PNP output and IP67-rated M18 metal housing

  • Photoelectric detection up to 200 mm range
  • PNP output with selectable light/dark switching
  • M12 4-pin connector for quick installation
  • IP67 metal housing withstands harsh environments
  • 10–30 V DC supply fits standard industrial power

Sick VTE18-4P2140 photoelectric sensor

The Sick VTE18-4P2140 is a cylindrical photoelectric proximity sensor that uses an energetic detection principle with an infrared LED. It operates on a 10 V DC to 30 V DC supply and provides a PNP switching output selectable for light or dark switching via a control cable. The M12 4-pin male connector and nickel-plated brass housing rated IP67 suit industrial automation tasks.

Ideal for presence detection on conveyors

This sensor suits engineers who need a compact M18 threaded unit with a 3 mm to 170 mm sensing range and a 250 Hz switching frequency for fast cycling. The 120 g metal body withstands –25 °C to +70 °C ambient temperatures. Buyers requiring background suppression, a teach-in button, or a longer range beyond 200 mm should look at alternative sensing technologies.

170 mm sensing range with 200 mm maximum

The energetic mode reliably detects standard targets up to 170 mm and reaches a maximum of 200 mm with a 10 mm light spot at that distance. A 2 ms response time and 100 mA output current handle typical PLC inputs. Detection becomes unreliable on low-reflectance surfaces or when the 2.8° beam divergence exceeds the target size at longer distances.

Questions about this item

What power supply must I already have to run the VTE18-4P2140?

A DC supply between 10 V and 30 V that can deliver at least 30 mA with ripple below 10 %.

Will the sensor work with my existing M12 4-pin cable?

Yes, the sensor uses a male M12 4-pin connector compatible with standard M12 4-pin cables.

How can I confirm the sensor is detecting correctly after wiring?

The output switches at up to 250 Hz with a 2 ms response; monitor the PNP signal while moving a target through the 3 mm to 170 mm range.
