Gecko Screw-Lok Metal Backshells

Harwin Gecko Screw-Lok (Gecko-SL) Metal Backshells feature a nickel-plated aluminum hood that fits over male or female crimp housing with six to 50 contacts over two rows. These backshells are designed to be used with nickel-coated copper braids for EMC / RFI purposes, polymer braids for mechanical protection, and polyurethane-coated fiberglass braids for heat applications. Harwin Gecko-SL backshells offer a cable housing or through-board hood with a horizontal or straight connector orientation for 1.25mm pitch connectors. These metal backshells have a -65°C to +150°C operating temperature and are RoHS compliant.
