Robust Circular Connectors of the Hirschmann CA Series Now Available in Several New Colours

Nov 8, 2010

The renowned circular connectors from the Hirschmann™ CA series that were previously only available in black can now be ordered from Belden in red, white and blue.This makes it possible to clearly label power supply, measurement and control interfaces, even when they all use the same basic connector.

The CA circular connectors are all UL- and VDE-approved, and thanks to their compact construction they are currently the smallest connectors on the market. Other features include a temperature range from 40 to +90°C and – provided they are correctly mounted and screwed together – protection category IP67. Meaning that these connectors can be used wherever maximum reliability is critical, for instance in machine building, traffic engineering and renewable energy applications.

The CA series includes straight and angled chassis, cable connectors and the corresponding couplings. All components are offered with three or six poles plus PE. The three-pole versions (3+PE) have a rated voltage of 400V AC or 250V DC with rated currents of 16A and 10A respectively. For the six-pole versions (6+PE) the corresponding values are 250V AC/V DC and 10A.

The straight and angled cable plugs and couplings are all 61 mm long. The corresponding chassis connectors measure 32.3 mm. All housing elements are made of chemically resistant polyamide, and must be firmly screwed together to ensure correct assembly. Cables are made up either by soldering (6+PE) or with screws (3+PE).

By issuing these new coloured versions, Belden has simplified the use of the Hirschmann™ CA connectors even more. “These circular connectors are remarkable for their compact design, impermeability and high mechanical and electrical resilience,” notes Product Manager Hartmut Unverricht, adding, “that’s why the CA series has become a recognized industry standard.”
