A coupling and control assembly including a sensor for providing an electrical signal for electronic transmission control is provided. The assembly includes a first coupling member which supports the sensor and a locking element and a second coupling member supported for rotation about a rotational axis. The second coupling member has a coupling face oriented to face radially with respect to the axis and has a set of ferromagnetic or magnetic locking formations. An electromechanical component is also supported by the first coupling member. Both the locking element and the sensor are in close-spaced opposition to the coupling face. The sensor senses magnetic flux to produce an electrical output signal indicative of a speed of rotation of the second coupling member. A variable magnetic field is generated in response to rotation of the locking formations past the sensor.
