STAUBLI 33.0504 – CT-SP8/25 AG
The STAUBLI 33.0504 is a pin contact for the CombiTac system. It is used when building a modular connector with high current capacity, while still having the freedom to customize the solution as needed. This is a contact with an 8 mm nominal diameter, designed for conductor cross-sections of 25 mm² (AWG 4).
The contact's silver-plated surface is relevant because it is part of the contact technology that ensures a stable connection in a professional plug system. It is rated for a nominal current of 117 A, and the catalog also provides very low contact resistance values and an average insertion force of 7.5 N / 5.5 N. This clearly indicates that it is designed for a solution where current conduction and repeated coupling must function reliably over time.
As part of CombiTac, it is designed for modular constructions where different contact and connection types can be assembled in the same frame or housing. This is precisely what makes the system interesting in industry and technology: you can combine multiple connections into one integrated connector instead of handling them individually.
CombiTac information specifies a lifetime of 100,000 mating cycles and that the system is specified with vibration and shock resistance according to IEC standards. This is important to consider when the connection is to be used in environments with many connections and disconnections.
