The ​JST Terminal series is a line of ​high-reliability electrical connectors specifically designed for ​PLC (Programmable Logic Controller) systems in industrial automation. These terminals are widely used for ​secure signal transmission between PLC I/O modules, sensors, actuators, and control panels. Featuring ​compact spring-clamp design, JST Terminals enable tool-free wire insertion, reducing installation time by 40% compared to screw-type terminals. Their ​0.5-4 mm² wire range compatibility supports both low-voltage digital signals and high-current power circuits (up to 41A). With ​IP67-rated waterproof variants, they excel in harsh environments like automotive assembly lines and food processing plants. A key innovation is the ​self-locking mechanism that prevents accidental disconnection under vibration – a critical feature for machinery with 10-500 Hz operational vibrations.


  1. ​Vibration Resistance: Patented ​dual-spring contact system maintains stable conductivity even under 50G shock loads (exceeds IEC 60512 standards).
  2. ​Space Optimization: 3.5mm pitch ultra-narrow design allows 30% denser wiring in control cabinets.
  3. ​Multi-Protocol Support: Compatible with ​PROFINET, EtherCAT, and CC-Link IE fieldbus systems through shielded variants.
  4. ​Color-Coded Safety: 12-color options for rapid error identification (e.g., red for emergency stop circuits).
  5. ​Maintenance Efficiency: Transparent housing enables visual inspection without disassembly.
