The JST JFA Connector J1000 Series is a versatile solution for both signal and power supply circuits, making it ideal for use in factory automation, heavy electric machinery, and a wide range of general industrial equipment. This series offers a variety of housing options while maintaining a standardized contact design, ensuring compatibility and simplifying assembly. The connectors feature a robust double-spring construction, providing enhanced stability and secure electrical connections. With a compact 2.2 mm pitch, the JFA Series supports wire sizes up to AWG #18. The inclusion of a housing lance and a secure locking mechanism ensures reliable mating retention, preventing accidental disconnections and enhancing system safety. Additionally, the standardized tooling for this connector family further optimizes production efficiency and reduces costs.
