Product context

Product description and application

Erich Jaeger 311311 is Adapter / Voltage Doubler 12V > 24V - - Connects 7P/12V socket (ISO 1724) on vehicle side with 7P/24V plug (ISO 1185) on trailer side. This adapter connects two connector standards or layouts. It is especially important to verify the pin allocation, because the mechanical fit alone does not prove that every lighting and auxiliary function is routed correctly. ISO 1724 - Type N, ISO 1185 - Type N and 12V should be verified against the vehicle or trailer wiring diagram. The known selection frame is ISO 1724 - Type N, ISO 1185 - Type N, 12V, 7P and commercial vehicles, cars, agriculture.

What does 311311 do?

This page treats 311311 as a real vehicle-electrical component, not just as a search term. In practice the part is selected by connector family, electrical standard, voltage, pole count and the way it is mounted or connected in the vehicle. For a adapter, the mating component and cable route are part of the decision.

Technical checks before replacing it

Check the product drawing, connector layout, mounting position, electrical load and mating component before treating another part as equivalent.

How ConnectorRoute approaches the alternative

ConnectorRoute starts with the Erich Jaeger number, then checks the application: vehicle type, yearly volume, existing mating connector, drawings or photos, required approval level and supply continuity. Only after that does an alternative become a quoteable route instead of a guess.

Products that belong in the same request

For a useful quote, include related system parts where possible: 101100 7P/12V Socket (ISO 1724 - Type N), 201212 7P/12V Plug (ISO 1724 - Type N), 511119 7P/24V supply cable - with 7P/24V socket (ISO 1185) and 8P connector (DIN 72580), 611080 7P/24V Coil (ISO 1185 - Type N), 101285 7P/12V Socket (ISO 1724 - Type N). That helps prevent solving one article number while leaving the matching plug, socket, coil cable, adapter or supply cable as the next bottleneck.

Questions about this reference

Can Erich Jaeger 311311 be replaced one-to-one?

Sometimes, but it should not be assumed from the article number alone. The connector standard, pole count, voltage, contact type, seal, cable entry and application need to match before ConnectorRoute confirms a replacement.

What should I send with an enquiry?

Send the Erich Jaeger article number, quantities, yearly demand, photos of the installed part, drawings if available, the mating connector and any vehicle or trailer information.

Why does the page mention related products?

Truck and trailer electrics are system-based. A socket, plug, coil cable, adapter and supply cable often need to be checked together to avoid a partial replacement route.
