JST WPJ Connector, Wire to Board, Custom Wire Assembly
JST WPJ Connector, Wire to Board Type
The JST WPJ Connector is a versatile and reliable 5.0 mm pitch disconnectable crimp-style connector designed for compact and durable electrical connections. Its adaptable design allows it to function in both waterproof and non-waterproof conditions by simply adding a rubber component, enabling seamless transitions between different applications. The connector features a shared header for both configurations, ensuring compatibility and ease of use. Its waterproof performance meets Grade 7 ingress protection standards (JIS C 0920 and IPX7 of IEC 60529), making it ideal for demanding environments. Additional highlights include a control key system for secure connections, an inner locking mechanism, a deformation-resistant contact design, and a compact form factor for space efficiency.
