    SIP Mould Reed Switch Series

    SIP Mould Reed Switch Series

    When a magnet or coil creates a magnetic field that acts on the switch, both reeds of the reed switch become magnetized. An N pole is formed on the contact point of one of the reeds, and an S pole is formed on the contact point of the other reed. If the attractive force of the generated magnetic field causes the contacts to conduct, the circuit is closed. Once the magnetic field weakens to a certain extent, the reeds will separate again due to elastic force, which means the circuit is disconnected.

    Reed Relay

    Reed Relay

    A reed relay is a relay that uses a coil to generate a magnetic field to actuate a reed tube. It is a coil sensing device. Therefore, the characteristics of reed relays are small size, light weight, fast response speed, short bounce time and other characteristics. Mainly used in measurement equipment, communication equipment, security equipment, medical equipment, etc.

    Industrial Relay

    Industrial Relay

    The main function of the relay is amplification. With a very small current, a circuit with a large power can be controlled, and the control range can also be expanded. When the signal reaches a certain value, the contacts can be switched simultaneously according to different forms of the contact group. Open and connect multiple circuits to achieve the purpose of automatic switching.
