STAUBLI 33.0509 – CombiTac pin contact
Stäubli 33.0509 is a pin contact for the CombiTac system. It is used when building a modular connector where high current needs to be transmitted in a compact contact solution.
The contact's size and design are specified as CT-SP6/16 AG in the CombiTac catalog. It is designed for a conductor cross-section of 16 mm² and a nominal pin/socket diameter of 6 mm. This makes it relevant in constructions where power connections are used in a modular connector system rather than fixed, separate connections.
In practice, this is a component chosen when the connection needs to be repeatedly connected and disconnected, yet still maintain low contact resistance and a stable electrical connection. The catalog specifies a rated current of 89 A, an average insertion force of 7.5 N, and a contact resistance of less than 250 μΩ.
The CombiTac series is developed for professional systems where the connector must be able to be integrated into machines and equipment with repeated couplings. For this contact, the manufacturer's data specifies 100,000 mating cycles as well as vibration and shock values, which are relevant in environments with movement and stress.
