    RHT stands as a leading Wire Protector Terminal Block Manufacturer, specializing in high-reliability Industrial PCB Terminal Block Wire Protector solutions. Our products integrate cutting-edge safety mechanisms to ensure secure connections in demanding environments, with full PCB Terminal Block Wire Protector Custom capabilities to meet unique application requirements.


    RHT’s PCB Terminal Block Wire Protectors are engineered for industrial-grade electrical connectivity, combining robust mechanical design with advanced safety features. These terminal blocks utilize a shrapnel clamping mechanism (phosphor copper or stainless steel) to grip wires via compression-release action, eliminating the need for manual screwing and enabling tool-free maintenance . Designed for PCB mounting, they support wire-to-board connections in automation, energy storage, and control systems, with certifications including UL, CE, VDE, and CB for global compliance .

    Key Features & Benefits

    1. Wire Protector Technology

    • Secure Clamping: Stainless steel or phosphor copper wire protectors exert constant pressure on conductors, preventing dislodgement under vibration or shock .

    • Dual Wiring Directions: Supports 90° and 180° wire entry for flexible routing in space-constrained panels .

    • Insulation & Safety: Integrated rubber grommets seal wire entry points, enhancing IP-rated dust/water resistance and mitigating electrical leakage risks .

    2. Industrial-Grade Durability

    • Materials:

      • Housing: Flame-retardant PA66 or PBT (UL94 V-0) for high-temperature resistance (up to +105°C) .

      • Contacts: Tin-plated brass for low resistance (≤20mΩ) and corrosion prevention .

    • Electrical Ratings:

      • Voltage: 250–600V (IEC/UL) .

      • Current: 10A–30A, supporting wires up to 2.5mm² (14–24 AWG) .

    3. Customization Capabilities

    • Pitch Options: 3.5mm, 5.0mm, 7.5mm, 10.0mm for high-density PCB layouts .

    • Pole Configurations: 2P–24P spliceable blocks, with modular bases for scalable installations .

    • Special Features:

      • Flip Covers: Transparent or colored lids with latching mechanisms to prevent accidental contact .

      • Temperature Monitoring: Optional embedded thermal fuses (e.g., 105°C trip) for overload protection .

    4. Industrial Applications

    • Control Panels: DIN rail-mountable designs for servo controllers, PLCs, and elevator systems .

    • Energy Storage: High-current handling for battery management systems (up to 30A) .

    • Harsh Environments: -40°C to +105°C operational range, ideal for outdoor/industrial automation .
