Autac Products Limited are now able to supply both the 7 core cable (4 x 6.00mm˛ and 3 x 1.00mm˛) and also the plugs and sockets to ISO 25981. ISO 25981:2008 specifies dimensional characteristics, contact allocation, tests and requirements of 7-pole connectors for electrical connections of electronically monitored charging systems of towing and towed vehicles. The electronic monitoring system is designed to detect 12 V and 24 V nominal supply voltage and to limit the current to 50 A. This is a connector without breaking capacity. This electrical connection is intended for use with truck-trailer combinations in order to connect an additional battery pack of the trailer with the generator of the truck using an electronically monitored charging system. Additional battery packs in trailers are basically used with tailgate lifts, electrical forklifts, refrigerated trailers or other technical equipment with high current consumption. If using this connection then the current should be electronically monitored with a limit of 50 A (this is very important to prevent overheating of the contacts). The plug and socket are based on the same shape and design of the existing EBS ISO 7638 plug and socket, but in ISO 25981 the plug and socket should be a light colour, and the keyway is located in a different position to prevent mismating with other connectors without use of excessive force.
