DK series

This polyamide/polypropylene level switch, supplied with nut, is fixed from the inside of the tank. With a small footprint, only 47 mm long, it is perfectly suited for applications in water up to 80°C.
The position of the float on the body allows the contact to be reversed (to be determined when ordering).
It can be reversed for installation at the bottom of the tank. The mounting orientation then determines the detection (high or low level).
