The OEX ACX0690 combines a 7-pin flat trailer socket with an integrated 50A Anderson style plug in a single black plastic housing, making it a practical solution for vehicles that tow and also need a direct battery-to-battery charging connection point. The 7-pin flat socket handles trailer lighting and braking circuits while the Anderson style plug provides a high-current feed for auxiliary battery charging or accessory power.
The socket includes a reed switch and is rated at 15A for the 7-pin trailer circuits and 50A through the Anderson style plug. It is compliant with AS4177.5-2004 and suits standard 12V towing setups. Note: compatibility with vehicle monitoring systems should be considered before installation removal of the LED may be required on some vehicles.

Confirm with supplier.
What is the Anderson style plug used for in this socket?
The integrated 50A Anderson style plug provides a high-current connection point — typically used for auxiliary battery charging between the tow vehicle and a caravan or camper trailer, or for connecting high-draw accessories directly. It is rated at 50A, suitable for DC-DC charger feeds and similar applications.
What does the reed switch do?
The reed switch detects whether the socket lid is open or closed and can be used to trigger a circuit or signal — commonly used to activate a battery-to-battery charging circuit when a trailer or Anderson plug is connected. Confirm the reed switch state (normally open or normally closed) with OEX before wiring, as the supplier data contains conflicting information on this point.
Will this socket work with my vehicle's monitoring system?
Compatibility with vehicle monitoring systems varies. OEX notes that the LED may need to be removed on some vehicles. Check with your vehicle manufacturer or auto electrician before installation if your vehicle has an active trailer or electrical monitoring system.
What trailer types is the 7-pin flat socket compatible with?
The 7-pin flat connector is the standard Australian trailer connector used on caravans, boat trailers, car trailers, and box trailers. It carries circuits for left and right indicators, tail lights, brake lights, reverse lights, electric brakes, and auxiliary power.
Is this socket compliant with Australian standards?
Yes. The ACX0690 is compliant with AS4177.5-2004, the Australian standard for trailer electrical connectors.
