A 19 pin circular connector, male, supplied with all its pins. The cable side half of a multi way connector for signal and low power runs that have to cross a panel together.
Nineteen ways through one sealed crossing is the reason to use it. A drive unit, a BMS or a controller typically needs a dozen or more signals to leave its enclosure: sensors, enables, feedback, supplies. Running those as individual connectors means a dozen penetrations, a dozen seals and a dozen things to disconnect for service. One circular connector makes it a single plug that comes apart in one movement and goes back the same way.
Circular connectors are also the right shape for the job: they seat by rotation, they lock positively, and they tolerate vibration far better than a rectangular multi way pressed into a mounting.
All the pins are included, so there is nothing else to order to make it off.

Compatibility
Mates with the 19 pin female panel mount connector. Buy the pair unless you already have the other half.
For EV retrofits, drive unit and controller harnesses, industrial machinery and any custom loom needing many ways through one connector.
This is a signal and low power connector, not a high voltage one. Traction circuits need the high voltage connectors, which carry interlocks and touch proof contacts that this does not.
