Chomerics Europe has worked with a automotive supplier to provide a solution to a design challenge they encountered on a rear windscreen antenna receiver unit for a European luxury vehicle manufacturer. The requirement was for an electrical connecter that, prior to Chomerics involvement in the project, had been achieved using metal spring finger stock. Using its CHO-SEAL 1285 conductive elastomer, Chomerics was able to design a custom extrusion that satisfied several important unmet needs. The low impedance connector supplied by Chomerics allowed high frequency radio signals from the glass-mounted antenna to pass easily through its structure. This helped to ensure quality reception for in-car multi-media and telematics devices. The same component also allowed current to pass in the other direction to power screen-mounted LEDs and other applications. CHO-SEAL 1285 is suitable for use at temperatures between –65ºC and +200ºC. It has a silicone binder / silver plated aluminium filler construction and allows engineers to design lightweight, compliant (65± 5 Shore A) mouldings for use in harsh environments.
