ESQT-124-02-F-D-425

ESQT-124-02-F-D-425 is a rectangular female socket manufactured by active-semi. It has a 4-way, Through-Hole Socket, 1-row, 2.54 mm / 0.100 inch Pitch, 2.9 mm / 0.114 inch Row Spacing. It features a Gold Flash HD Contact Plating, 24 AWG Wire Gauge and is Non-Locking. The socket has a peak electrical rating of 125V at 2A, with an operating temperature range of -40°C to +85°C. It also has an insulation resistance of 100 Megohms minimum at 500 VDC, dielectric withstanding voltage of 500V AC per EN 60950-1, and contact resistance of 20 milliohms maximum.

Application Field

The ESQT-124-02-F-D-425 is primarily used in industrial and computing applications. It can be used in applications that require fast and reliable electrical connections with low contact resistance and superior signal integrity. It is especially well suited for automotive electronics, industrial robotics, harsh environment test and measurement equipment, and other high power/speed signal transfer applications. It is also often used in complex circuit boards in consumer electronics and industrial automation systems.

Working Principle

The ESQT-124-02-F-D-425 is an electrical contact that has been engineered and designed to maximize the efficiency of a signal transfer. It is composed of a contact made of metal with an insulating material, along with a contact spring that provides a connection between the contact carrying wires and the contact pads on the board. The contact spring helps to maintain the contact between the wires and the board even under harsh vibration and extreme environmental conditions.

The ESQT-124-02-F-D-425 is capable of carrying signals at high speeds and providing superior signal integrity. The presence of the contact spring helps to minimize the contact resistance and reduce the risk of signal loss. The contact spring is designed to provide a reliable and repeatable connection and helps to ensure maximum connection density.

The ESQT-124-02-F-D-425 also features a Gold Flash HD Contact Plating that helps to increase corrosion resistance and reduce contact oxidation. The higher plating thickness also helps to reduce contact resistance and wear out. The non-locking design helps to reduce inadvertent detachment of the connector while maintaining a secure connection.

Conclusion

The ESQT-124-02-F-D-425 is a reliable and robust rectangular female socket that is designed for fast and reliable connections. It is suitable for a wide range of industrial, computing, consumer, and automotive applications. It features a contact spring that helps to provide a secure connection and reduce contact resistance, and a gold flash HD contact plating which helps to increase corrosion resistance and reduce contact oxidation. The non-locking design helps to reduce inadvertent detachment of the connector while maintaining a secure connection.
