BALLUFF Capacitive Threaded Barrel Proximity Sensor, M18, 20 mm Detection, PNP NO, 10 → 30 V dc

Our standard inductive sensors are ideal for object detection in metal areas. They are short-circuit protected and operate without contact, making them wear-free and very resistant to dirt and contamination. The sensors are available in configurations from 3 mm Ø to 80 x 80 mm square dimensions.
The rugged and reliable inductive Global Sensors provide especially economical solutions.
