    High Sensitivity PCB Power Relay / 18F-4C 14 Pin Miniature Power Relay With 4 Contacts

    General purpose relay 18F-4C 14pins with 4 contacts, 27.5*21.5*35mm


    Description:

    A relay switch can be divided into two parts: input and output. The input section has a coil which generates magnetic field when a small voltage from an electronic circuit is applied to it. This voltage is called the operating voltage. Commonly used relays are available in different configuration of operating voltages like 6V, 9V, 12V, 24V etc. The output section consists of contactors which connect or disconnect mechanically. In a basic relay there are three contactors: normally open (NO), normally closed (NC) and common (COM). At no input state, the COM is connected to NC. When the operating voltage is applied the relay coil gets energized and the COM changes contact to NO. Different relay configurations are available like SPST, SPDT, DPDT etc, which have different number of changeover contacts. By using proper combination of contactors, the electrical circuit can be switched on and off. Get inner details about structure of a relay switch.


    Features:

    Low coil power consumption

    High sensitivity.
    Small size, light weight.
    PC board mounting.


    Applications:

    Relays are used in electronics to switch a smaller current which in turn will control larger current. They prevent the user to have direct contact to the main device being controlled that might be holding high voltage. These devices are comparable to a remote c ontrol which is used to make a big electronic equipment work.

    CAUTION:

    1.The use of any coil voltage less than the rated coil voltage will compromise the operation of the relay.
    2.Pickup and release voltage are for test purposes only and are not to be used as design criteria.
    3.Unless otherwise stated, the rated coil voltage specified in coil parameter tableshall be used for all tests and its application to the relay
