Inductive sensor SP-05NB, NC/NPN 10-30VDC

SP-05NB is a board-mounted inductive proximity sensor for non-contact detection of metal objects. It is intended for installation in fixed mechanical assemblies where output switching is required when the set sensing distance is reached. The design with a cable and a rectangular body with mounting holes facilitates installation in machines, fixtures and automation units.
