STAUBLI 33.0531
Stäubli 33.0531 is a CombiTac contact for Ø 3 mm assembly in the CombiTac uniq system. It is used when building a modular connector where the same overall solution can be assembled with different contact types as needed. This is a contact for conductors in the 2.5–4 mm² range.
In practice, it is a spare part or component for a larger plug connection, not a finished plug in itself. It therefore belongs in solutions where power transfer is handled in compact and assembled connections. In the catalog, it is listed with an IEC-rated current of 26–39 A, depending on the version, and it is specified with a contact resistance of less than 1.1 mΩ. This is worth noting in professional use, because low contact resistance typically means less loss in the connection itself.
The contact is also specified for 100,000 mating cycles. This indicates that it is designed for repeated use in systems where equipment is frequently disconnected and reconnected. The average insertion force is 8 N, which helps provide a more controlled connection in the modular system.
If you work with CombiTac uniq, the 33.0531 fits in as part of the flexible design, where you choose contact size and current level according to the application.
