Connector Material The Optical Converter simply attaches to the strobe's electrical bulkhead in place of a sync cord connector. This product features a hard anodized aluminum connector. If you have an older strobe with a nickel plated brass (silver color) bulkhead, then we recommend returning your strobe to have the bulkhead updated to anodized aluminum to prevent seizing of the connectors.
