Photoelectric Proximity Sensor – VTF18-4P1140

The VTF18-4P1140 photoelectric proximity sensor is engineered with background blanking for accurate object detection in tight spaces and environments with interfering backgrounds. Housed in a robust M18 x 1 nickel-plated brass body, it offers reliable performance in industrial automation and sensing tasks requiring high focus and precision.

Equipped with a focused infrared LED, the sensor can detect objects within a sensing range of 3 mm to 90 mm, with a light spot diameter of 3 mm at 50 mm distance. It supports light/dark switching, a 4-wire PNP output, and is rated IP67 for harsh environments.

No adjustment is necessary, making it a plug-and-play solution ideal for applications where simplicity and repeatability are crucial.
