Industrial proximity sensor
The Sick VTE18-3P2140 is a cylindrical photoelectric proximity sensor with a PNP dark-switching output. It operates on a 10 V DC to 30 V DC supply and draws a maximum of 30 mA. The metal and plastic housing carries an IP67 enclosure rating for dust and water resistance. It is suited for automation engineers who need reliable object detection in industrial environments.
Build integration requirements
The sensor mounts in an 18 mm threaded barrel and connects via a 4-pin M12 male connector. Infrared LED emission with a 2.8° dispersion angle provides a sensing range from 3 mm to 170 mm, extendable to 200 mm maximum. A potentiometer allows range adjustment without software tools. The brass nickel-plated housing and PMMA optics withstand ambient temperatures from –25 °C to +70 °C.
Sustained load behaviour
Response time is specified at 2 ms with a ripple tolerance of 10 % on the supply line. Dark-switching logic means the output activates when the beam is interrupted, maintaining state during continuous presence detection. UL file NMFT2.E175606 confirms compliance for North American control panels. The sensor is not for applications requiring analog distance output or AC supply voltages.

Questions about this item
How far can the sensor reliably detect an object at its maximum sensing range of 200 mm?
The sensing range max is 3 mm ... 200 mm, while the standard sensing range is 3 mm ... 170 mm using infrared LED light with a 2.8° dispersion angle.
What is the power consumption and enclosure rating when the sensor runs continuously on a 10–30 V DC supply?
Power consumption is 30 mA with a 10 % ripple allowance, and the brass nickel-plated metal housing meets IP67 for dust and water protection.
Which mating connector and mounting hardware are required to install the M12 4-pin male connector on this sensor?
A compatible 4-pin M12 female cable or field-wireable connector is needed, plus suitable brackets for the 78 mm cylindrical metal housing.
