IEC 60603-7-51:2010涵盖了8路、屏蔽、自由和固定连接器，参考了IEC 60603-7中的尺寸、机械、电气和环境特性和测试，并规定了频率高达500 MHz的电气传输要求，包括功率和外来（外源）串扰。这些连接器可与IEC 60603-7-1第2条中定义的其他IEC 60603-7系列连接器进行互配和互操作。 这些连接器与其他IEC 60603-7系列连接器向后兼容。

IEC 60603-7-51:2010 covers 8-way, shielded, free and fixed connectors, references dimensional, mechanical, electrical and environmental characteristics and tests in IEC 60603-7, and specifies electrical transmission requirements, including power sum alien (exogenous) crosstalk, for frequencies up to 500 MHz. These connectors are intermateable and interoperable with other IEC 60603-7 series connectors as defined in Clause 2 of IEC 60603-7-1. These connectors are backward compatible with other IEC 60603-7 series connectors.
