The CD50CNF07NC is a capacitive level detector designed for non-contact liquid level sensing. It operates on a 10-30 VDC supply and features a fixed rated operating distance of 7 mm, providing a 3-wire open collector NPN transistor output with break switching (NC) logic. Housed in a 50 x 30 x 7 mm Noryl enclosure with an IP67 rating, it is designed for robust performance. This sensor is ideal for applications such as monitoring water levels in non-metallic storage tanks for mini-pools and whirlpools, or as a safety device to control pump operations.
