Sick VTF18-3N5312 photoelectric sensor
The Sick VTF18-3N5312 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. The brass nickel-plated metal housing carries an IP67 enclosure rating for dust and water protection. This unit suits automation engineers and electricians who need reliable object detection in industrial environments.
Sensing range 0 mm to 45 mm with 50 mm maximum
The sensor delivers a guaranteed sensing range of 0 mm to 45 mm and a maximum reach of 50 mm using infrared LED light. A built-in potentiometer allows fine adjustment of the switching point for the application. Response time is 2 ms, enabling detection of fast-moving targets. Performance drops beyond the 45 mm assured range, so critical detection zones should stay within that distance.
2 m PVC cable connection for 10 V DC to 30 V DC
A 2 m PVC cable with 0.14 mm² conductors and a 3.1 mm diameter provides the electrical connection without a separate plug. The sensor fits into a 60.6 mm deep mounting space and operates from –25 °C to +70 °C. UL file NMFT2.E175606 confirms compliance for North American installations. The fixed cable length limits placement flexibility in larger panels.

Questions about this item
Will the VTF18-3N5312 operate on my existing 10 V DC to 30 V DC power supply?
Yes, the sensor accepts a supply voltage range of 10 V DC to 30 V DC with a ripple of 10 %, so any source within that window will power it.
How can I verify the sensor is detecting objects correctly after wiring it?
With dark-switching NPN output and a 2 ms response time, the output goes low when the infrared beam is reflected back; watch the PLC input LED toggle as a target enters the 0 mm to 45 mm sensing range.
Does the box include a mounting bracket or must I order one separately?
The unit ships with a 2 m PVC cable attached; no bracket, reflector or separate connector is included in the package.
