STAUBLI X-GL-438
The STAUBLI X-GL-438 is a 4 mm in-line plug for self-assembly of test leads. It is used when building or adapting test leads for test and measurement equipment where secure connection and reliable contact are required.
The plug features a spring-loaded MULTILAM contact, a retractable sleeve, and a protective collar. In practice, this means it is designed to minimize the risk of accidental contact while providing the necessary clearances for safe use. This also makes it relevant for older test instruments that are not yet equipped with safety sockets.
Assembly is done with screw connection, allowing the wire to be easily mounted in a professional workshop or laboratory setup. The stated ratings are 600 V, CAT II, and 32 A, and the electrical contact is made of CuZn with a nickel surface.
This is a component suitable for environments where test leads must be robust, safe, and compatible with 4 mm systems.
Typical applications
Used for assembling test leads for measurement equipment in electronics, service, and electrical engineering, where 4 mm connections are used.
