ABSTRACT:
A variable reluctance magnetic transducer including a tubular housing having a closed end and an open end. A bracket is attached to the outside of the housing a predetermined distance form the closed end of the housing. A core supporting a ferrous metal pole piece and a permanent magnet is disposed within the housing with an end of the pole piece contacting the inside of the closed end of the housing to accurately position the pole piece end relative to the bracket. The core supports a pair of fork terminals which engage arcuate blade terminals carried by a cap assembly. The blade terminals allow positioning of the cap assembly at a plurality of angles relative to the core and housing.
