WALTHER Plug and Socket

Walther's pin & sleeve devices are built to IEC 309-1 and 309-2 specifications and are interchangeable with other manufacturers who conform to the IEC standards and color coding system...anywhere in the world. Manufacturers that do not comply with the standards have their own proprietary configurations and are not plug compatible with other pin & sleeve products. Once you have selected a proprietary configuration you are locked in to a single source. Specifying IEC 309-1 & 309-2 devices provides convenience and flexibility that users have come to accept almost without thinking.
