Photoelectric Proximity Sensor – VTE18-4P4740

The VTE18-4P4740 is a robust photoelectric proximity sensor using the energetic detection principle. Its compact M18 cylindrical design with axial optical axis makes it ideal for industrial sensing applications requiring high accuracy and fast response. The sensor uses infrared LED light, with a sensing range of up to 350 mm and adjustable sensitivity via a 270° potentiometer.

It features light/dark switching, selectable via control cable, and supports PNP output. Designed for tough environments, the IP67-rated housing is made of durable PBT/PC plastic with a PMMA optical surface, ensuring reliability even in demanding conditions.
