Battery pack connector meets rail industry standards

The CombiTac connector system from Multi-Contact can be used to connect battery packs used on rolling stock and other rail applications. Featuring alignment tolerances of 3° and ±1mm through standard CombiTac guiding end pieces, the panel mount connectors are suitable for use with rackable, slide-in battery packs where blind connection is necessary.

Able to be configured with or without signal contacts, the connectors are compliant with rail standards including EN 50467 and EN 61373, as well as fire and smoke standard EN 45545-2. The modules can also be configured to suit other battery power transmission and monitoring applications such as charging stations, EVs, military vehicles, aircraft and naval vessels.

A typical configuration has two 12mm diameter power contacts and 12 1.6mm signal contacts for monitoring battery parameters such as temperature. Various sizes of power contacts can accept a wide range of cable cross-sections and a make first / break last pilot contact can also be included.

The CombiTac connector system features a rated insulation voltage up to 3700V (depending on pollution degree and overvoltage category), withstand voltages of 12kV on signal contacts and 8kV on power contacts, rated current of up to 400A and IP2X touch protection up to 1000V.

Operating over a temperature range from -40 to +120°C, the connector components can be supplied separately, or preassembled and tested. Termination is by crimp or screw for 50-120mm2 cross-sections for power contacts and crimp only for signal contacts from 0.5-1.5mm2.
