Modular connectors combine multiple contact types
I
n electronics, electrical connectors need to be reliable, with low contact
resistance and long lifetimes. They also frequently need to be rugged, compact and shock resistant. Combining these features, with the additional advantage of being modular, is the CombiTac connector system from Multi-Contact.
A wide range of contact types can be included, enabling application specific requirements to be met using standard components. Typical applications are for portable test equipment in the laboratory and on the production line, as well as power uses in factory automation, battery packs and power electronics modules.
Modules can carry current levels of up to 300 A and voltages as high as 5 kV, and all the necessary signal and data contacts can be included within the single space saving connector. Suitable for rack and panel mounting or within an appropriate housing, they are rated at up to 100,000 mating cycles.
Because of their robust design, combined with a float mounting capability which compensates for misalignment in slide-in applications, heavy rack modules can be quickly and easily inserted without the risk of damaging the contacts.

One example of the type of connector that can be included in the CombiTac system is the new 10 Gbit Ethernet module, which can connect Cat 6a cabling via its RJ45 sockets. Supplied fully assembled, the module can provide high speed data communications in harsh environments such as the factory floor.
The modules can be fitted with any combination of high voltage, high current, data, fibre optic, power, thermocouple and coaxial contacts, and even media such as pneumatics and hydraulics. Touch protection is provided to ensure safety when high voltages are being used. They can be easily added
or reconfigured on site, enabling changing requirements to be met without the need for purchasing new connectors. They achieve their long
term reliability due to the use of MULTILAM technology, a proprietary contact system that uses multiple torsion spring contact elements that allow electrical contact to be made via a large number of contact points. This arrangement substantially reduces contact resistance and ensures strong resistance to shock and vibration.
