JST BNI Connector, Wire to Board, Custom Wire Assembly
JST BNI Connector, Wire to Board Type
The JST BNI Connector is a 3.3 mm pitch wire-to-board solution designed for reliability and safety in electronic applications. It features an incomplete mating prevention mechanism, ensuring proper and secure connection during assembly. To prevent mismatched insertion, especially in configurations where multiple connectors are used within the same system, the BNI connector offers three distinct keying patterns. Its design includes a robust keying structure, a secure locking device for enhanced stability, and an inertia lock mechanism for added protection against accidental disconnection. Additionally, the connector supports a retainer for increased retention force and features a header optimized for potting processes, making it suitable for environments requiring additional insulation or moisture resistance.

Note:
- The current rating differs depending on the number of circuits and the wire size used in each connector. The table above lists the current rating as a function of the number of circuits and the wire size.
- Do not branch in parallel current which exceeds the rated current (e.g. more than 4 A in the case of 2 circuits with AWG #20). If branched in parallel, current imbalance or other problems may develop. If it is absolutely necessary to branch such a large current in parallel, design the circuits without causing any imbalance and provide an extra margin for each circuit.
