31-220N Description

Short technical summary and product information.

The Amphenol RF 31-220N is a BNC jack to BNC jack coaxial adapter designed for same-series connections. It features a straight body style with female center contacts on both ends, providing a reliable interconnect for 50 Ohm systems. The adapter supports frequencies up to 4 GHz and uses a bayonet lock fastening mechanism for quick and secure mating.

 

This adapter is panel mounted with a bulkhead mounting feature, making it suitable for fixed installations where a pass-through connection is required. The center contacts are silver plated for good conductivity and corrosion resistance. The adapter is RoHS3 compliant and has an MSL of Level 1 (unlimited).
