Modular connectors for harsh environments A


major concern in applications where harsh environmental and rough handling


conditions are present is the exposure to external forces, vibrations and shocks that damage contacts used for power, data and signal transmission. In industries such as machinery, oil & gas and power generation, there is certainly a need for more robust and reliable connectors to ensure servicing and maintenance is reduced to the minimum, saving long-term costs and time. Multi-Contact’s modular connector line, CombiTac, allows individual combination of different contact types in one compact connector, combining power and signal, thermo- couple, coaxial, fibre optics, fluid and compressed air connectors in a single frame or housing according to the user’s needs.


In applications where heavy slide-in motor control centre modules are regularly inserted and removed from switchboards, there is a high risk of damaging contacts because of excessive forces and connection misalignment. In addition, low-quality individual contacts are not designed to withstand such rough handling. In such cases, and due to the float mounting feature of CombiTac, damage to contacts and connection misalignment is easily avoided.


Because of the robust design and


CombiTac is a modular connector range from Multi-Contact.


MC Multilam technology used, the CombiTac contacts are characterised by their low contact resistance, ability to achieve high mating cycles, and high resistance to vibrations and shocks This demonstrates that CombiTac is an ideal modular connector for harsh environments and rough handling conditions.


The CombiTac line boasts a number of features that allow the range to stand out in the marketplace. These include: up to 300A; up to 5kV; up to 100,000 mating cycles; up to 15 bar; float mounting; and various sizes for panel mounting or DIN housing up to IP68. There is also an online configurator and supply of real 3D STEP files. It is a complete solution, with cable assembly on request.


CombiTac is finding fans in a variety of industries and appplications.


Examples of successful uses include: as a BUS connector in a test system for all controls in the passenger cabins of the A380; in a battery charging station with slide-in technology for railway power supply units; as a connection for a high-power laser; and as connections to mobile trolleys in operation rooms for medical technology.


There is a wealth of possible connections, including: electric; thermocouple pressure contacts; coaxial; optical fibre; compressed air; liquid; electric + PE; and data transfer. In summary, the CombiTac line more than lives up to its tagline of 'One for all – all in one'. l
