It seems to me that BNC connectors are only used for coaxial cables. These coaxial cables with BNC connectors are very practical when it comes to plug and play quickly.
But for a balanced signal chain STP cable is used not coaxial. But what equivalent connector is common in electronic instrumentation for STP(twisted shielded pair) cables. Is there a standard plug&play conventional connector for STP? (By plug and play I mean not screw terminal sort of thing but indeed a connector which is similar to BNC or a jack one can easily remove and plug in a second)
