7 PIN EBS ROUND PLUG AND SOCKET

Effective from January 1st 2015 all new trailers (exceptions apply) need to comply to ADR38/04 that specifies they have either Anti-Lock Brakes (ABS) or an Electronic Brake System (EBS) to automatically adjust the brakes. EBS (Electronic Brake System) connectors are used for the electrical connection of the ABS/EBS braking systems between the truck and trailer for both 12V and 24V electrical systems. Whilst ABS has 5 pins, EBS requires two additional contacts (7 total pins) to permit the exchange of data between cab and trailer to optimise the braking effect. The plugs are connected to the sockets with a steel latch to avoid accidental disconnection. The sockets are provided with a plug expulsion system in case the plug is incorrectly connected. Mechanical resistance and watertightness guarantee an efficient and reliable electrical connection.
