A speed sensor (B, C) produces a signal that reflects the angular velocity of a shaft (4) which rotates in a case (2) having a mounting surface (10), beyond which the shaft projects to provide a target (6), and threaded holes (12) which open out of the mounting surface. The speed sensor includes a housing (20) and a sensing element (22) which is embedded in the housing. The housing, which is formed from a deformable material, has slots (44, 60) which align with the threaded holes in the case, and receive screws (24, 66) which thread into the holes to secure the speed sensor to the case. The speed sensor is positioned such that the proper air gap exists between its sensing element and the target. The screws, which extend through the slots, produce indentations (56, 74) in the deformable material of the housing, and these indentations receive the screws, so that the position of the sensor is fixed. Thus, the sensor, if removed, may be reinstalled in the same location.
In combination with a mounting surface out of which a threaded hole opens and with a target which rotates in front of the surface about an axis that is oriented at a steep angle with respect to the surface, and with a screw having a threaded shank that threads into the hole and a head at the end of the shank;
A process for installing a speed sensor against a mounting surface out of which a threaded hole opens so that the speed sensor can monitor the rotation of a target that revolves in front of the mounting surface about an axis oriented at a steep angle with respect to the surface, the sensor including a housing having a slot and along the slot being formed from a deformable material, the sensor further including a sensing element located in the housing and being capable, in response to rotation of the target, of producing a signal that reflects the angular velocity of the target, said process comprising:
