Abstract
Techniques for detecting mating and un-mating of a first connector with a second connector include providing a pulsed voltage signal at a contact of the second connector and measuring a rate of rise of voltage at the contact. If the measured voltage at the contact exceeds a threshold voltage during the time the pulsed voltage signal is applied, then it is concluded that the first connector is not present and not mated with the second connector. If the measured voltage is lower than or equal to the threshold voltage during the time of application of the voltage pulse, it is concluded that the first connector is present and mated with the second connector.
