Core Specifications and Parameters

  • Q What materials are used in HRB connectors (housing, terminal plating)?

    A
    HRB connectors use high-performance housing materials including PA66, PBT and PA9T, with flame resistance ratings of UL94 V-0 and UL94 V-2 to suit diverse environments.
    Terminals are made of high-strength brass or phosphor bronze. Standard tin plating ensures durability, while gold plating provides superior conductivity and signal stability. All components comply with RoHS standards for reliable industrial and consumer applications.

  • Q What is the operating temperature range of HRB connectors?

    A
    HRB connectors are designed with a wide operating temperature range to fit various environments.
    Standard series operate reliably from -40 °C to +125 °C, suitable for consumer electronics, household appliances and industrial equipment. High-grade and high-power models can withstand extreme temperature fluctuations, ensuring stable performance in long-term operating conditions.

  • Q What current and voltage ratings do HRB connectors support?

    A
    HRB connectors offer versatile current and voltage specifications.
    Standard series support 1 A to 50 A and 125 V to 600 V for daily electronic and household equipment.
    High-power models can reach 120 A, meeting high-current industrial and energy storage requirements.

  • Q What is connector pitch and how do I choose the right pitch size?

    A
    Connector pitch is the distance between adjacent pins of a connector. It determines structural compatibility and electrical performance.
    Choose the proper pitch according to your equipment size, wiring space and power demand. Compact devices use small pitch, while home appliances and industrial products adopt larger pitch for higher safety and stability.

  • Q What are the key specifications of HRB connectors (pitch, current, voltage)?

    A
    HRB connectors match JST/Molex/TE in key specs:
    Pitch: 1.27, 2.0, 2.54, 3.0, 3.81, 3.96, 4.14, 4.2, 5.08, 6.35, 10.0mm
    Current: 1A–50A (standard), up to 120A (high-power)
    Voltage: 32V–600V (standard), up to 1500V (automotive/energy)
    Certified: UL, cUL, VDE, RoHS, suitable for industrial, automotive, and consumer electronics.
