Product Series: J4000 Series
The J4000 Series connectors, including J4200S and J4300S models, are designed for robust electrical connections. They feature various circuit counts and keying options for secure mating. The series includes receptacle housings and headers with different entry types (side and top). Keying prevents incorrect mating, and optional protectors on some header types prevent foreign substance insertion. These connectors are suitable for PC board mounting with specified land and through-hole dimensions.
