Industrial proximity sensor
The Sick VTE18-3N4912 is a cylindrical photoelectric proximity sensor designed for industrial automation and machine-building applications. It detects objects using an infrared LED with a 2.8° dispersion angle and provides a dark-switching NPN output. The plastic housing meets IP67 enclosure rating for dust and water protection. Suitable for installation in harsh environments.
Sensing range up to 350 mm
The sensor operates reliably from 5 mm to 350 mm with a maximum reach of 400 mm. A potentiometer allows precise adjustment of the switching point for the specific target distance. Response time is 2 ms, supporting fast production-line cycles. The 10–30 V DC supply range suits standard industrial power rails.
Low power draw and wide temperature range
Power consumption is 30 mA at 10–30 V DC with 10 % ripple tolerance. The unit functions continuously from –25 °C to +70 °C without derating. A 2 m PVC cable with 0.14 mm² conductors and 3.1 mm diameter provides flexible routing. UL file NMFT2.E175606 confirms compliance for North American installations.

Questions about this item
How far will the Sick VTE18-3N4912 actually detect an object once it is mounted in the machine?
The sensor offers a maximum sensing range of 5 mm to 400 mm and a defined operating range of 5 mm to 350 mm, so reliable detection is guaranteed up to 350 mm in practice.
What does the NPN output and 10 V DC to 30 V DC supply voltage mean for wiring this sensor into my control system?
The NPN switching output pulls the load to ground when the beam is blocked, and the unit operates on any 10 V DC to 30 V DC supply with less than 10 % ripple, drawing a maximum of 30 mA.
What mounting clearance and cable routing do I need for the cylindrical angled housing of the VTE18-3N4912?
The housing measures 60.6 mm across, uses a 2 m PVC cable of 3.1 mm diameter with 0.14 mm² conductors, and meets IP67 for wet or dusty environments.
