Magnetically-operated cylinder switch for monitoring hydraulic actuator has magnetic field sensor on circuit board in housing, arranged in direction of polar axis of magnetic field from piston magnet

摘要

A permanent magnet is arranged on the working piston of the actuator. A magnetic field sensor (3) is arranged in the inner region of a sensor housing (1) in the direction of the polar axis of a radially-oriented magnetic field of the piston, and on a printed circuit board (2).
