Title: Speed sensor having a UV-cured glue seal and a method of applying the same

Abstract: A speed sensor assembly is provided that isolates the internal components of the speed sensor from detrimental external environmental influences. Further provided is a new seal that seals between a housing and an overmold of a speed sensor and is capable of use in speed sensors of varying types and of all different sizes and shapes. Provided is a seal in which a bead of glue cured by ultraviolet light is applied around part of the exterior surface of a housing, after which an injected molded plastic overmold is applied over at least that part of the housing having the applied ultraviolet cured glue. In this way, once the housing is overmolded, the ultraviolet cured glue forms a gasket-like seal between the housing and the overmold preventing the penetration of water or other contaminants into the internals of the speed sensor. Also provided is a mounting fixture for use during a process of applying the seal to the housing.
