Sick VTE18-3P8712 Photoelectric proximity sensor PNP
A cylindrical photoelectric proximity sensor with a 10–700 mm sensing range, PNP dark-switching output, and IP67-rated PBT housing for 10–30 V DC supply
- PNP output simplifies wiring for standard PLC inputs
- 10–800 mm sensing range covers short and medium distances
- Infrared LED with 2.8° dispersion gives a focused 40 mm spot at 800 mm
- IP67 enclosure and –25 °C to +70 °C rating suit harsh industrial environments
- 250 Hz switching frequency supports fast production-line cycles
Sensing range up to 800 mm
The Sick VTE18-3P8712 is a cylindrical photoelectric proximity sensor that detects objects using energetic infrared light. It operates on 10 V DC to 30 V DC and provides a PNP dark-switching output with a maximum load of 100 mA. The 3-wire PVC cable measures 2 m with a 3.1 mm diameter and 0.14 mm² conductors. An IP67 enclosure rating protects the PBT/PC housing and PMMA optics in harsh environments.
Sustained detection stability
Sensing range adjusts via a 270° potentiometer from 10 mm to 700 mm, while the maximum detection capability reaches 800 mm with a 40 mm light spot at that distance. The LED source produces an approximate 2.8° dispersion angle for consistent beam geometry. A 250 Hz switching frequency and 2 ms response time support reliable cyclic operation on continuous production lines. Circuit protection A, B, C and D guard against common electrical faults during extended use.
Voltage and output limits
Supply voltage must stay within 10 V DC to 30 V DC with ripple below 10 % to maintain specified performance. The PNP output sinks up to 100 mA, restricting the sensor to direct PLC inputs or small relays rather than heavy loads. Operating temperature spans –25 °C to +70 °C, and the UL file NMFT2.E175606 confirms compliance for North American installations. The fixed 2 m cable length defines the maximum distance to the termination point without additional connectors.

Questions about this item
What is the power consumption of the Sick VTE18-3P8712 when operating continuously on a 10 V DC to 30 V DC supply?
The sensor consumes a maximum of 30 mA with a supply voltage range of 10 V DC to 30 V DC and a ripple of 10 percent, making it suitable for continuous operation in industrial environments.
What power supply and cabling does the Sick VTE18-3P8712 require to function?
It needs a 10 V DC to 30 V DC supply and comes with a 2 m, 3-wire PVC cable of 0.14 mm² cross-section and 3.1 mm diameter for direct connection.
Will the Sick VTE18-3P8712 fit existing M18 mounting points and work alongside legacy 250 Hz control systems?
Yes, the M18 x 1 thread diameter matches standard mounting holes and the 250 Hz switching frequency aligns with typical legacy PLC cycle times for reliable integration.
