IEC 61076-2-109:2014描述了具有IP 65/IP 67防护等级的圆形连接器，适用于频率高达500 MHz的数据传输。应用包括但不限于视觉系统和数据采集。这些连接器由固定和自由连接器组成，可重新布线或不可重新布线，带有M 12 x 1螺钉锁紧。公连接器有圆形触点和空触点；0.6毫米。本标准涵盖两种不同类型的连接器，分别命名为X和H，具有不同的触点布置，不可相互互换，但具有共同的额定值和用途。 关键词:连接器，圆形连接器，数据传输

IEC 61076-2-109:2014 describes circular connectors with IP 65/IP 67 degree of protection and suitable for data transmission with frequencies up to 500 MHz. Applications include, but are not limited to, vision systems and data acquisition. These connectors consist of fixed and free connectors, either rewireable or non-rewireable, with M 12 x 1 screw-locking. Male connectors have round contacts ∅ 0,6 mm. This standard covers two different types of connectors, denominated X and H, with different contact arrangement, not mutually interchangeable, but with common ratings and purposes.
