STAUBLI SAM-4N-46
The STAUBLI SAM-4N-46 is a 4 mm in-line test plug for self-assembly of test leads. It is used when you want to build a test lead with a secure and electrically safe plug connection at the end, typically for measuring equipment and test setups in electrical and electronics work.
The plug has a spring-loaded MULTILAM contact, which provides a stable contact surface, and it comes with a rigid insulating sleeve. The cable connection is made with a screw terminal, allowing the conductor to be mechanically secured during assembly. It accepts cables up to 4.6 mm in outer diameter and conductor cross-sections up to 2.5 mm².
With rated data of 1000 V CAT II and 600 V CAT III, as well as 32 A, it is designed for demanding test and measurement tasks where high voltages and currents are involved within the specified categories. The contact's base material is CuZn with nickel surface treatment, which is relevant for both contact and durability in use.
As a test accessory according to IEC EN 61010-031, the SAM-4N-46 fits into professional work tasks that require both safety and a practical construction of test leads. In short, it is a spare part and a building component for test leads, not a finished lead itself.
