IEC 63171-5:2022是指测试和测量、环境测试以及无焊料连接的国际标准。IEC 63171的这一部分描述了具有IP65/IP67 M8或M12锁定的双向屏蔽或非屏蔽圆形连接器，通常用于频率高达600 MHz、载流量高达4 A的平衡单对数据传输，用于环境条件恶劣的区域。这些连接器包括固定连接器和自由连接器，可拆线或不可拆线。阳连接器具有方形截面触点。

IEC 63171-5:2022 refers to International Standards for test and measurement, environmental testing as well as solderless connections. This part of IEC 63171 describes 2-way shielded or unshielded circular connectors with IP65/IP67 M8 or M12 locking, typically used for balanced single-pair data transmission with frequencies up to 600 MHz and with current-carrying capacity up to 4 A, for use in areas with harsh environmental conditions. These connectors consist of fixed and free connectors, either rewirable or non-rewirable. Male connectors have square cross-section contacts.
