What is IEC 63138 ‑ 2 about?
IEC 63138-2 is one of the parts of IEC 63138. IEC 63138-2 is a sectional specification (SS), provides information and rules for the preparation of detailed specifications (DS) for MQ4 series circular connectors with four RF channels, as well as a detailed specification of the blank format.
An MQ4 series circular connector with 50 Ω nominal impedance has four RF channels which can be engaged and disengaged at the same time. There are two versions of plug connectors, one is a quick-lock version, and the other is a threaded version. The socket connector provides two coupling mechanisms, a quick-lock, and a threaded coupling.
IEC 63138 ‑ 2 also specifies the mating face dimensions and gauging information of MQ4 series circular connectors, and t...
