Rectangular Connectors - Headers, Receptacles, Female Sockets are essential components in electronic devices. The ESQT-109-02-S-S-309 is a commonly used rectangular connector for electrical devices. It is applicable to a wide range of applications and it is one of the most popular choices for electrical power connectors.

The ESQT-109-02-S-S-309 is a rectangular connector with a 30-pin configuration. It is made of nylon/PA 66 material, and it has a UL 94V-0 rated flame-retardant insulation. This connector is also RoHS compliant and non-halogen. The contact material consists of brass with gold or silver plating. This connector is mostly used in high-current applications due to its high contact efficiency, stability and tightness.

In terms of its application field, the ESQT-109-02-S-S-309 is widely used in various electronic devices such as industrial automation system, home appliance, smart device, solar energy system, LED lighting, communication modules, etc. It should be used with a cable with an outer diameter of 3.00~5.00mm and an insulation jacket of 0.8~2.0mm. The rated current and voltage are 35A/625V AC, respectively.

The ESQT-109-02-S-S-309 connector consists of four sets of contacts. These contacts ensure maximum power conductivity while protecting the device from damage due to overloads or short circuits. The contact resistance is less than 0.3mΩ and the insulation resistance is greater than 1000mΩ. The temperature range of use is from -40°C to +105°C.

The working principle of the ESQT-109-02-S-S-309 connector is very simple. The male terminal is inserted into the female connector and the locking clip on the male terminal locks onto the female connector. This ensures that the connection is secure. The terminal has a built-in spring system which ensures that it is securely connected and that it will not become disconnected due to external forces. This spring system also helps maintain a good mechanical and electrical seal.

In conclusion, the ESQT-109-02-S-S-309 is an ideal choice for electrical power connectors with its 30-pin configuration, UL 94V-0 flame-retardant insulation, RoHS compliant, and high contact efficiency. It is applicable to a variety of applications in industries such as automation, home appliance, communication modules and LED lighting. Its four sets of contacts ensure a secure connection and maximum power conductivity. Moreover, the built-in spring system ensures that it is securely connected and that it will not become disconnected due to external forces.
