JST JWPS Connector
The JST JWPS Connector is designed specifically for applications requiring reliable waterproofing. This wire-to-board connector meets Grade 7 ingress protection standards of JIS C 0920, equivalent to IPX7 as defined by IEC 60529, ensuring optimal performance in wet or challenging environments. Key features include exceptional waterproof performance achieved through a contained seal ring and solid rubber seal. The double-spring construction enhances contact reliability, while housing-to-terminal locks ensure secure connections. Additionally, the connector is equipped with a mis-mating prevention key, reducing the risk of incorrect assembly. These features make the JWPS Connector an ideal choice for demanding waterproof applications.
