- NPN output for simple PLC integration
- 3–90 mm sensing range covers close and mid targets
- Infrared LED with potentiometer for easy range setup
- IP67 plastic housing survives wash-down and dust
- 10–30 V DC supply fits standard control panels
Sick VTF18-3E1712 Proximity Sensor
The Sick VTF18-3E1712 is a cylindrical photoelectric proximity sensor with an NPN switching output. It operates on a 10 V DC to 30 V DC supply and offers a sensing range of 3 mm to 90 mm. The housing carries an IP67 enclosure rating and uses a 2 m PVC cable for connection.
Check Supply Voltage and Wiring
Verify that your control system provides a DC supply between 10 V and 30 V with ripple below 10 %. The sensor draws up to 30 mA and uses an NPN light-switching output, so the load must be wired to the positive rail. Confirm the 2 m cable length and Ø 3.1 mm diameter suit your routing and termination plans.
Suits Short-Range Detection Tasks
This unit suits automation tasks needing infrared detection up to 90 mm in environments down to –25 °C or up to +70 °C. It is not for applications requiring PNP output, longer sensing distances, or connectorised termination instead of a flying lead. Buyers who need a different switching mode or housing style should look at other sensor types.

Questions about this item
Does the Sick VTF18-3E1712 arrive with a mounting bracket or only the 2 m cable?
The sensor ships with a 2 m PVC cable already attached; no mounting hardware is included and must be sourced separately.
When should I choose the NPN light-switching version instead of a PNP or dark-switching model?
Select this NPN light-switching unit when your control input pulls low on detection and the target reflects more infrared than the background.
How does the 2 ms response time affect detection on a fast conveyor?
At 2 ms the sensor can reliably register objects passing at speeds where each target remains in the 3 mm to 90 mm sensing window for at least a few milliseconds.
