Sick VTF18-3N5912 photoelectric sensor

The Sick VTF18-3N5912 is a cylindrical photoelectric proximity sensor with an NPN dark-switching output. It operates on a 10 V DC to 30 V DC supply and detects objects up to 45 mm away using an infrared LED. The IP67-rated plastic housing suits industrial automation tasks where reliable presence detection is required.

Cable connection and potentiometer adjustment

A fixed 2 m PVC cable with 0.14 mm² conductors and a 3.1 mm diameter terminates the unit, so no separate connector is needed. Sensitivity is set via a built-in potentiometer; the only common issue is over-tightening the cable gland which can damage the sheath. The 2 ms response time supports fast cycling on conveyor or packaging lines.

Check voltage range and mounting clearance

Verify that the control system provides 10 V DC to 30 V DC with ripple below 10 % and can sink the NPN output. Confirm the 60.6 mm housing length and angled light exit fit the available bracket space. The sensor withstands –25 °C to +70 °C ambient temperatures, matching typical factory environments.

Questions about this item

How do I verify the sensor is operating correctly after wiring it to a 10 V DC ... 30 V DC supply?

The sensor will switch its NPN output in dark-switching mode when an object enters the 0 mm ... 45 mm sensing range; response time is 2 ms.

What comes in the box and what must I purchase separately?

The sensor ships with a 2 m PVC cable (Ø 3.1 mm, 0.14 mm² conductors) permanently attached; no mounting bracket or separate connector is included.

Which sensing range variant should I select for a 45 mm detection point?

This model offers a maximum sensing range of 50 mm and a rated sensing range of 45 mm; choose it when your target distance falls within 0 mm ... 45 mm.
