High voltage connectors have been added to the range of options for Multi-Contact's versatile CombiTac connector system. The standard module size contact carriers can be supplied with one or two poles, which are fitted with a PTFE insulating sleeve housing 3mm diameter pins and sockets.

Rated voltages are 5kV between cables, and 2.9kV between cables and earth. Rated currents are 20A for the dual pole carriers or 32A for single pole carriers. When mated, the panel mount connector offers IP2X environmental protection - this can be improved to IP65 when mounted in standard hoods, with options for IP67 or IP68 on certain sizes.

Contacts are gold plated, and the sockets are fitted with Multilam torsion spring technology for maximum reliability. Termination is by crimping onto 2.5mm2 high voltage flexible copper cable and applying heat shrink tubing. The outside diameter of the lead insulation should not exceed 6.6mm.

"Unlike many other connector systems, CombiTac is designed to withstand a high number of mating cycles," said Multi-Contact UK managing director Selwyn Corns.

In addition to high voltage contacts, the CombiTac system can be fitted with databus, power, thermocouple, coaxial, fibre optic, pneumatic and fluid connectors in any combination. The contact carriers are housed in a compact, robust frame for panel mounting or built into DIN coupler hoods.
