JST JFA Connector J2000, Custom Wire Assembly Manufacturer
JST JFA Connector J2000 Series
The JST JFA Connector J2000 Series is a versatile solution designed to support the miniaturization of electronic equipment. It offers two locking options — center locking and side locking — allowing for flexible application-specific usage. The series features a unified design for receptacle and tab contacts, ensuring compatibility across all JFA J2000 variants. With a dual-spring construction, these connectors deliver enhanced contact stability and secure engagement. The inclusion of a housing lance provides reliable terminal retention, while the distinct "click feeling" offers tactile feedback to confirm proper connection. This combination of features ensures high performance, ease of use, and adaptability for compact electronic devices.
