Abstract
A vehicle variable reluctance sensor includes a hollow generally cylindrical sensor housing with an open proximal end. Within the interior of the sensor housing is a coil wound around a “T”-shaped spool. The coil is connected to two electrical terminals by two electrical leads. A channel is formed in the spool between the coil and the electrical leads and the electrical leads are disposed within the channel. The channel is flanked on each side by a lip that extends outwardly from the spool. If the electrical leads become slack under extreme temperatures, the configuration of the channel, in conjunction with the lips, prevents the electrical leads from coming out of the channel and unwinding the coil. As such, it is not necessary to tape the coil or otherwise immerse the coil in varnish to prevent the coil from unwinding.
