What is BS EN 60512-23-7 - Assessing the screening effectiveness of connectors about?
Electrical connectors are used to join electrical conductors to create an electrical circuit.
BS EN 60512-23-7 defines a test method that is intended to assess the screening effectiveness of screened non-circular multi-pole, electrically short, connectors by the measurement of the effective (surface) transfer impedance ZTE expressed in Ω, using a network analyzer, for frequencies up to 1 GHz.
The test in BS EN 60512-23-7 is based on the line injection test method according to IEC 61196-1 with a specific type of injection wire, which is adapted to the shapes of connectors. Due to the specific test set-up used in the method described in BS EN 60512-23-7, the connector screen itself is not verified, but the combination of two connectors (male and female) together, i.e. the test results include the effectiveness of the screens of the two connectors and the joint between the connectors and the joints of the cable to the connector.
