A system may include a first connector housing, a magnetic data storage device mechanically coupled to the first connector housing, a second connector housing configured to be mechanically engaged with the first connector housing, and a permanent magnet mechanically coupled to the second cavity. In some examples, relative motion between the magnetic data storage device and the permanent magnetic causes data stored on the magnetic data storage device to be modified. In one example, the system further includes a printed board assembly mechanically coupled to one of the first or second connector housings and a master interconnect board mechanically coupled to the other one of the first or connector housings. Modification to the data stored on the magnetic data storage device may indicate relative movement between the first and second connector housings.
