The 87400-125LF provides a secure, reliable, and cost-effective solution for a wide range of applications. With its unique design, the 87400-125LF allows for quick connectivity and termination, and its compatibility with a variety of systems thereof.

Application Field

The 87400-125LF is commonly used for connecting multiple items, such as external memory cards, PC peripherals, and other system components. It can also be used for medical, automotive, and military applications. The 87400-125LF is well-suited for high-speed data transmission, and its convenient design makes it easy to use.

Design

The 87400-125LF consists of two rows of 42 pins. Each pin is terminated with a gold plated alloy tip and a dielectric base to ensure reliable electrical connection. The connector has two different lengths: a long side and a short side. The long side has five pins in two rows. The short side has three pins in one row. The connector is constructed from a UL 94V-0 material, and can withstand temperatures up to 125°C.

Working Principle

The 87400-125LF uses a standard 3-pole, 4-wire contact system. This system consists of two levels of contacts with three pins each, with an additional pin in the lower level. The upper level is connected to the device\'s motherboard, and the lower level is connected to the device itself. The lower level contact is the signal contact, which receives and sends data signals. The signal contact is also used to control the speed of the data transmission. The upper level contact is the power contact, which provides power to the device. The 87400-125LF connector provides a secure connection between the device\'s motherboard and the device itself. The connector\'s robust construction ensures a reliable, low-resistance connection. The device\'s electrical components are thus supplied with power and data signals without interference or signal loss.

Conclusion

The 87400-125LF is a robust rectangular connector header with male pins. It is used for both power and signal applications and is well-suited for high-speed data transmissions. The connector header is made from UL 94V-0 material, and is rated up to 125°C. The used 3-pole, 4-wire contact system ensures a secure connection between the device\'s motherboard and the device itself. This connector provides a secure, reliable, and cost-effective solution for a wide range of applications.
