  • Self-adjusting magnetic sensor
    Patent number: 4612501
    Abstract: A sensing mechanism has a retainer ring which is secured in an aperture formed in a housing in which the sensor is to operate. The retainer ring has a plurality of tabs which cooperate with axial and circumferential slots on the sensor to permit removal and replacement of the sensor without the need for adjustment. On original installation of the sensing mechanism, the retainer ring is positioned in the housing aperture by radially extending tines cooperating with the aperture. A resilient member permits the mechanism to be installed to a depth deeper than the operating depth. The resilient member urges the sensor axially, as permitted by a gap between the retainer ring and the circumferential slots, to achieve the proper operating depth.
