DP Seals and Ridgemount Technologies build great connections

DP Seals and Ridgemount Technologies build great connections

DP Seals has completed development of an intricate seal for Ridgemount Technologies, the European designer, developer and manufacturer of specialised fibre optic connector interfaces. The seal, which has a unique cross sectional profile, is for a new connector which will be used in military, industrial and hazardous environments, in particular, immersion and exposure to weather extremes. In all cases maintaining optical continuity for communication, data or sensing is essential. Product failure is not an option.

Drawing on DP Seals’ expertise and experience of customising solutions for harsh environments, one aspect of the project required the over moulding of rubber onto a tubular anodised aluminium substrate ensuring compliance to stringent MIL specifications. 

The other challenging aspect of the project was the face seal. This is a vital component as it not only locates and seals the precision optical insert within the shell of the host connector but also performs a critical dynamic function at the optical mating face. To do this it displaces into a predetermined diametric cavity, so as not to impair the functionality and optical performance of the mating optical inserts, whilst also maintaining the sealing of the host connector. 

Mark Limbert, technical director at Ridgemount, is delighted with the end result. He comments: “Through the product development process DP Seals has played a vital role in delivering technical excellence and a first class product in a timely manner. Such service levels and confidence make managing new product introductions relatively stress free.”

DP Seals managing director Andrew Piper is equally pleased, saying: “This product is another example of DP Seals responding quickly to the challenging problems and high specification requirements of customers who need custom rubber mouldings for harsh environments.”
