Contrinex Photoelectric Proximity Switches Fibre Optic Amplifier for DIN Rail - Contrinex 620 000 913, This photoelectric proximity switch uses fibre optic technology to produce a sensor that is ideal for use in e.g. explosive or strong magnetic environments, where electrical signals may present a risk of explosion or may not function correctly. The sensor is designed to be DIN rail mounted and can be easily stacked for multi-sensor operations. The maximum switching distance is 200mm and there is adjustment between 20 to 200mm via an illuminated-scale, 12-turn potentiometer. A bar graph indicaed signal strength and excess gain and there is a function to switch from light-ON to dark-ON. Contrinex 620 000 913
