Abstract
An encapsulated transducer (10) includes an injection molded encapsulation ensconcing a sensing element (90) proximate the front end (22) and a portion of an information transmitting medium (120) emanating from the back end (24). A component alignment preform (40) operatively couples the sensing element (90) with the information transmitting medium (120). The preform (40) includes a front ferrule (70) and a rear ferrule (80) bonded thereto and linearly spaced apart along a long axis 'A'. The preform (40) further includes an annular recess (44) in which the sensing element or coil (90) is placed. A first lead (98) and a second lead (100) of the coil are electrically connected to the front ferrule (70) and the rear ferrule (80), respectively. A back end (48) of the preform (40) receives a stripped end (122) of the cable (120) such that a plurality of conductors are operatively coupled to the front ferrule (70) and the rear ferrule (80) and to the leads of the coil. A protective sleeve (150) is transfer molded over the coil (90) and interlocked with the preform 40 thereby forming a sleeved coil and cable assembly (170). The sleeved coil and cable assembly (170) is symmetrically disposed within the injection molded encapsulation (20) comprised of a seamless mass including an integrally formed protective front wall having an uniform thickness 'T' along a forwardmost portion of the sensing element (90) and seamlessly transitioning into an uninterrupted side wall circumscribing the sensing element and a portion of the cable.
