The panel mounting half of a two pole high voltage connector, A keyed, accepting both 35 mm² and 50 mm² cable. It mounts through an enclosure wall and takes either of the matching 90 degree plugs.
Taking two cable sizes is the useful part. Conversions rarely settle on one conductor size across a whole pack, and a connector that suits only one forces the cable choice instead of following it. The same panel part works whether the run turns out to be 35 or 50 mm².
It carries a high voltage interlock. A small signal loop is complete only while the plug is fully home. Wired into your BMS or contactor control, it opens the contactors as soon as the plug starts to move, so the power contacts never part under current.
A keyed parts mate only with A keyed parts. The moulded keyway physically blocks a B keyed half, which is what stops two similar runs being crossed. Check the letter on both halves before ordering.

Features
- Accepts 35 mm² and 50 mm², so the connector does not dictate the cable size
- Integrated high voltage interlock that breaks before the power contacts
- A keying physically blocks mating with a B keyed half
- Panel mount, so it becomes part of the enclosure rather than hanging off it
Compatibility
Mates with the A keyed 90 degree plugs in 35 mm² and 50 mm². Buy the pair unless you already have the other half.
For EV pack enclosures, inverter and charger housings, energy storage and industrial high voltage distribution.
The ratings are set by the whole assembly, not this half alone. What the joint carries depends on the plug, the terminals and the cable fitted to it. If you are working to a specific voltage and continuous current figure, ask us and we will confirm against the manufacturer data.
