- Detects objects up to 200 mm away with infrared LED sensing
- Reliable switching in 2 ms response time for fast automation cycles
- NPN light-switching output integrates directly into standard PLC inputs
- IP67-rated plastic housing withstands dust and water immersion
- Operates from 10 to 30 V DC across –25 °C to +70 °C
Industrial proximity sensor
The Sick VTE18-3E2712 is a cylindrical photoelectric proximity sensor with an NPN switching output. It operates on a 10 V DC to 30 V DC supply with a maximum power consumption of 30 mA. The housing measures 63.6 mm and uses infrared LED light with a 2.8° dispersion angle. A 2 m PVC cable with 0.14 mm² conductors provides the connection.
Suited for short-range detection
This unit suits applications requiring object detection between 3 mm and 170 mm with a light-switching response time of 2 ms. The IP67 enclosure rating and –25 °C to +70 °C operating range support harsh industrial environments. Buyers needing sensing distances beyond 200 mm or PNP output logic should look at alternative sensor models.
Consistent performance under load
The sensor maintains its specified 2 ms response time during continuous operation thanks to a low 30 mA current draw. Ripple tolerance of 10 % on the supply voltage ensures stable switching without false triggers. The PMMA optics and plastic housing resist contamination, preserving the 3 mm to 170 mm sensing window over extended duty cycles.

Questions about this item
What supply voltage must the existing control cabinet provide for the SICK VTE18-3E2712 sensor?
The sensor operates from 10 V DC to 30 V DC with a maximum 10 % ripple, so the cabinet must deliver a DC voltage within that range.
Will the 2 m PVC cable with 0.14 mm² conductors reach an existing junction box mounted nearby?
The cable is 2 m long, 3.1 mm in diameter and uses 0.14 mm² conductors; measure the distance to your junction box to confirm the length is sufficient.
How can I verify the sensor is detecting correctly after wiring the NPN output?
With the potentiometer adjusted, the amber LED lights when the NPN output switches in light-switching mode, confirming detection within the 3 mm to 170 mm sensing range.
