The Antenna Interface Standards Group (AISG) published this AISG standard to describe and define the AISG connector for RS-485 (AISG C485) (based on IEC 60130-9), typically used for AISG outdoor applications. Different connector vendors and connector styles are used within the control infrastructure of antennas and antenna line products, such as RET, TMA, Sensor- and monitoring- devices. Outdoor connector applications require good protection against environmental conditions to ensure waterproofness.
This Standard describes circular connectors with IP 68 protection degree (definition see 5.3.1). These connectors consist of fixed and free connectors, either rewireable or non-rewireable, with M16 x 0,75 screw-locking.Male connectors have round contacts Ø1,5 mm.
The contact terminations shall be of the following types: crimp or solder.Links
