Heavy-duty multi-pin connectors provide environmental sealing up to IP69K

April 9, 2026

The A Series™ family from Amphenol Sine Systems provides sealed plastic and metal interconnects, offering high-performance power and signal routing in harsh environments.

Amphenol Sine Series provides the A Series, consisting of sealed, heavy-duty, multi-pin plastic and metal connectors. The series encompasses 16 core connector lines engineered to route power and signals in harsh environments such as agricultural machinery and military architectures. 

 

Housed in either thermoplastic or metal enclosure, the connectors provide protection against physical impact. High-temperature silicone is used for environmental seals, enabling Ingress Protection (IP) ratings ranging from IP65 to IP69K when the connectors are mated. 

 

The internal structure of the A Series incorporates wedgelocks to maintain proper contact alignment and retention during exposure to shock and vibration. An integrated latching system with over-sized detents establishes a secure mechanical and electrical connection, with support for stamped and formed, machined, and RADSOK® contact types. 

 

The A series is compatible with existing standard industry connector interfaces, allowing integration into established cable assemblies.
