What is ISO 12098 about?
ISO 12098 gives the dimensions of, and specifies the contact allocation and tests and test requirements for 15-pole connectors for the electrical connection of equipment other than braking systems and running gear of towing and towed vehicles with 24 V nominal supply voltage. ISO 12098 specifies a park socket used to receive and store the plug when disconnected, and a means of adaptation between 7-pole and 15-pole connectors.
Who is ISO 12098 for?
ISO 12098 on 15-pole connector for vehicles with 24 V nominal supply voltage is useful for:
- Towing vehicles manufacturers
- Towing companies
- 15-pole connectors manufacturers
- Designers of towing vehicles
Why should you use ISO 12098?
ISO 12098 provides dimensions for the plug, socket and park socket which will give you guidance when manufacturing 15-pole connector.
ISO 12098 will make it impossible to make contact between any tube or pin of the plugs and sockets without the use of excessive force.
Commercial road vehicles with nominal 24 V supply voltage may be equipped with 7-pole 24 N or 24 S electrical connectors in accordance with ISO 1185 or ISO 3731, or with a 15-pole connector in accordance with ISO 12098.
Satisfactory adaptation between 7-pole and 15-pole connectors is only feasible when the vehicles involved are equipped with connectors which fully conform to the specifications of these International Standards.
In order to ensure interchangeability between vehicles equipped with the 7-pole connectors and those equipped with the 15-pole connector, an adapter designed in accordance with the requirements in ISO 12098 shall be used.
