Sick VTE18-3P2340 sensor for industrial detection
The Sick VTE18-3P2340 is a cylindrical photoelectric proximity sensor designed for object detection in automation environments. It operates on a 10 V DC to 30 V DC supply with a PNP dark-switching output. The infrared LED source provides a sensing range up to 200 mm with a 2.8° dispersion angle. An IP67-rated brass and plastic housing suits harsh conditions.
Low power draw and fast response
Power consumption is limited to 30 mA with a 10 % ripple tolerance on the supply line. The sensor delivers a response time of 2 ms for timely switching events. Operating temperatures span –25 °C to +70 °C without active cooling. The metal housing dissipates heat passively during continuous operation.
Potentiometer adjustment and M12 connector
A built-in potentiometer allows manual sensitivity adjustment for the 3 mm to 170 mm sensing range. Connection uses a male M12 4-pin plug for quick integration into existing cable networks. PMMA optics resist impact and contamination in dirty environments. UL file NMFT2.E175606 confirms compliance for North American installations.

Questions about this item
How do I mount the cylindrical angled housing and wire the M12 4-pin connector for the 10-30 V DC supply?
Mount the 75 mm brass nickel-plated barrel using its threaded body, align the angled light emission toward the target, then plug the M12 4-pin connector into a 10-30 V DC PNP input ensuring ripple stays below 10 % and the dark-switching output matches your controller logic.
What ongoing maintenance does the IP67 rated photoelectric sensor need in a –25 °C to +70 °C environment?
Periodically clean the PMMA optics to prevent infrared LED signal loss, verify the potentiometer setting has not drifted from vibration, and inspect the M12 connector seals for damage that could compromise the IP67 rating at temperature extremes.
At what distance does the 2.8° infrared beam spot size become the limiting factor for reliable detection?
The 2.8° dispersion angle widens the spot as range increases; beyond the 170 mm sensing range the beam diameter grows large enough to reduce contrast on small targets, making spot size the first limit under sustained use.
