A JST connector is a small electrical connector widely used in electronics and lighting, including LED applications. The abbreviation JST stands for Japan Solderless Terminal , indicating that it is a solderless connection.
Features of JST connectors
- Compact size : They are small and suitable for applications where space is limited.
- Various pin configurations : They are available in 2-pin, 3-pin and more depending on the application.
- Locking Mechanism : Many JST connectors have a click mechanism to prevent loosening.
- Used for low voltage connections : Typically used for 5V, 12V or 24V LED strips, batteries and small electronic circuits.
