1. A method of assembling a speed sensor in a housing that has cylindrical bore with a longitudinal axis, the method comprising the steps of:
- seating a planar circuit board in the bore to extend across the longitudinal axis;
joining one end of an elongated flexible circuit member to the circuit board so that the flexible circuit member extends therefrom in a direction generally parallel to the longitudinal axis;
providing a dielectric support for positioning in the housing; and
supporting a planar Hall effect sensor to extend across the longitudinal axis of the bore so that leads of the sensor extend from the sensor and through spaced apart channels in the dielectric support for connection with the circuit board.

Abstract
A robust and compact speed sensor assembly that includes a Hall effect sensor with protective circuitry in a compact housing that can be attached to the wheel of a motorcycle in the vicinity of the brake rotor to present the sensor Hall plate in a proper transverse-to-target orientation to detect passing targets, such as the brake rotor mounting bolts or magnets.

9. A method of assembling a speed sensor in a housing that has cylindrical bore with a longitudinal axis, the method comprising the steps of:
-
seating a planar circuit board in the bore to extend across the longitudinal axis; joining one end of an elongated flexible circuit member to the circuit board so that the flexible circuit member extends therefrom in a direction generally parallel to the longitudinal axis; providing a dielectric support for positioning in the housing; supporting a planar Hall effect sensor to extend across the longitudinal axis of the bore so that leads of the sensor extend from the sensor and through the dielectric support for connection with the circuit board; forming the housing to include an annular internal shoulder; and seating the circuit board on a dielectric seating ring that is located in the bore and abutting the internal shoulder.
