STAUBLI SAL-4N-39-TW
The SAL-4N-39-TW is an extra slim 4 mm plug for self-assembly of test leads. It is used when building a test lead with a compact termination that is still suitable for professional measurement work. Its in-line design and rigid insulation sleeve make it suitable as a cable end in test and measurement setups where soldering is involved.
Internally, the plug is constructed with spring-loaded MULTILAM contacts, which is the contact solution Stäubli uses in this series. The contact surface is nickel-plated, and the contact material is CuZn. These details are relevant when choosing a spare part or a component for self-assembly, as they provide information about both the contact structure and material selection.
The plug is rated for 1000 V, CAT II, 32 A and 600 V, CAT III, 32 A. Furthermore, the maximum cable diameter is Ø 3.9 mm, and the maximum conductor cross-section is 2.5 mm². The outer diameter is 8.0 mm.
If you are working with the construction or repair of test leads, this is a small, targeted component for the part of the task where the connection to the lead needs to be secure and compatible with the test equipment.
