Systems, devices, and methods for connectors

A circuitry is disclosed having one or more circuits and a connector portion coupled that is to the one or more circuits. The connector portion includes a plurality of pins, at least some of the pins having assigned functionality, and wherein at least one first pin is to activate a mechanism to bring the one or more circuits into an electrically safe state. The circuitry is configured, in case the connector portion is coupled with a first connector in a first orientation, to allow the one or more circuits to operate properly via the connector portion. The circuitry is also configured so that in a case where the connector portion is coupled with a second connector in a second orientation different from the first orientation, the at least one first pin of the plurality of pins receives a reference potential that triggers activation of a safety mechanism.
