PENTACONN φ4.4 balanced connection relay JACK [NBC1-14-001]

・It is a φ4.4 balanced connection relay jack, please use it for self-made applications (conversion cable, etc.).
・It has the same structure as NBA1-24-001 (substrate type), and uses a special copper alloy with extremely low conductor resistance and improved insertion/removal durability with high springiness.
・Due to the structure with 2 contacts per pole, the resistance value is stably reduced.
・High sound quality is achieved by using hard alloy plating composed of non-magnetic material for the base plating of gold plating
