    A Certified company with CE certificates.
    Advanced technical support and strict quality management system.
    High-efficiency and timely service by E-mail, Whatsapp,Facebook,etc.
  • Q What is the difference between an epoxy contactor and a ceramic contactor?

    A 1. The sealed material and process are different, the sealed material of epoxy is epoxy, and the production requires a baking process.
    The sealed material of ceramic products is technical ceramics, and laser brazing is required for production.
    2. The filing gas inside the product is different, the epoxy product is filled with nitrogen, and the ceramic product is filled with hydrogen.
    3. The return signal function of ceramic products is unstable and unreliable.
  • Q ls the whole product series non-polarized?

    A Yes
  • Q What are the causes of coil overheating or burning?

    A 1. The power supply voltage is too high.
    2. Poor coil manufacturing or due to mechanical damage, insulation damage, etc.
    3.The ambient temperature is too high.
  • Q How to check the sound of no action of the product?

    A 1. Confirm whether the wiring of the contactors coil control loop is reliable.
    2. Confirm whether the positive and negative poles of the coil are reversed.
    3. For products with auxiliary switches, confirm whether there is a phenomenon that the coil is reversed from the lead wire of the auxiliary switch.
    4. Confirm whether the output power of the power supply meets the driving power of the contactor coil.
