Sick

Sick VTE18-3N2440 Photoelectric Proximity Sensor NPN

SKU CH-35QH-YCA87

Photoelectric proximity sensor detects objects from 3 mm to 170 mm using infrared LED with NPN dark-switching output and IP67-rated brass housing

  • IP67 enclosure resists dust and water ingress
  • 10–30 V DC supply fits common industrial power rails
  • NPN dark-switching output simplifies PLC integration
  • 3–200 mm sensing range covers close and mid-range detection
  • M12 4-pin connector enables quick, secure wiring

Industrial proximity sensor

The Sick VTE18-3N2440 is a cylindrical photoelectric proximity sensor with an NPN dark-switching output. It operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 30 mA and connects via a 4-pin M12 male connector. The metal housing is nickel-plated brass with plastic components and carries an IP67 enclosure rating for dust and water protection.

Sensing range and adjustment

The sensor detects objects from 3 mm up to 170 mm reliably, with a maximum sensing range reaching 200 mm. Infrared LED emission with a 2.8° dispersion angle provides a focused detection beam suited to short-range positioning tasks. A built-in potentiometer allows manual sensitivity adjustment to suit the application and target surface.

Thermal and electrical behaviour

Ambient operating temperatures span –25 °C to +70 °C, matching the storage range, so the unit tolerates harsh industrial environments without derating. The low 30 mA current draw and 2 ms response time keep power dissipation minimal during continuous operation. UL file NMFT2.E175606 confirms compliance for North American installations.

Questions about this item

Will the VTE18-3N2440's M12 4-pin connector fit the cables I already use with older sensors?

The sensor uses a standard M12 4-pin male connector, so existing M12 cables will plug straight in.

How can I verify the sensor is detecting correctly once it's powered?

With 10–30 V DC applied, the NPN dark-switching output pulls low when the infrared beam is interrupted; measure the signal with a multimeter or watch the PLC input LED.

Does the box include a mounting bracket or an M12 cable, or do I need to order them separately?

The sensor ships as the bare unit only; a mounting bracket and a 4-pin M12 cable must be purchased separately.
