ABSTRACT:
A magnet sensor or "proximity switch" for sensing reciprocation of for example a spool within a lubrication distributor block. The sensor provides a threaded nozzle for screwing into the block with a bore therethrough. A magnet holder extends out of the nozzle and mounts a magnet thereto recessed inside the housing. The magnet holder is moveable reciprocally by the reciprocating spool. A sensor body is connected to the housing and holds a magnetic sensing element such as a Hall effect sensor adjacent to the housing for sensing the proximity of the magnetic field of the reciprocating magnet.
