Introduction

The SDL-121-TT-10 is a popular rectangular connector on the market, and the name signifies it’s a121-pin D-type connector with ten socket contacts. It’s commonly used in mobile device circuitry for connecting different electronic components. This article will discuss the fields of application and its working principles for the SDL-121-TT-10.

Application Field

The SDL-121-TT-10 is commonly used in mobile devices such as Smartphones, tablets, laptops, and wearables. Its low profile and high pin density make it perfect for use in tightened spaces in these devices. It also has a small form factor which makes it easier to install and more cost-effective to use than larger connectors. Furthermore, its re-mateable feature allows it to be unplugged and plugged multiple times without losing performance, making it an ideal choice for those applications which require iteration. The SDL-121-TT-10 is also used in the automotive industry for increasing wiring efficiency. The connector’s ability to handle high current flows makes it a preferred choice for signal and data transfers in cars. It is also utilized for designing flexible and durable interior automotive lighting systems. Additionally, the connector fulfills the gap between traditional board-mount connectors and field-installable connectors, making it a perfect fit for harsh environmental conditions in automotive industries. Finally, the connector is also seen used in aerospace, communications, and medical applications. This is because of its resistance to both EMI and ESD, and also because of its low weight, making it suitable for space-constrained applications.

Working Principle

The SDL-121-TT-10 is designed to attach two or more circuits together. It has a male side, a female side, and a hybrid side. On the male side, there are pins which make contact with the female side’s socket. On the hybrid side, there are pins and sockets which are detachable. The device works using an axial-pin technology. It holds a male pin on one side and a female socket on the other side. To mate the two sides, the pins are inserted into the female socket and then secured with a snap-in mechanism or a screw. This provides a firm connection between the two sides. The SDL-121-TT-10 is designed to be resistant to both EMI and ESD. Its construction consists of an insulative jacket, wire, and an inner dielectric band which protect the connector from radio frequency interference. The inner dielectric band also helps protect against the transfer of electrical charges. The SDL-121-TT-10 is also designed to be temperature, vibration, and shock resistant.

Conclusion

In summary, the SDL-121-TT-10 is a popular rectangular connector used in many applications. It has a low profile and small form factor, making it ideal for use in mobile device circuitry, automotive systems, aerospace, medical, and communications applications. This connector is designed to have an axial-pin technology, and is highly resistant to EMI and ESD. With its wide range of features and applications, it is an excellent choice for connecting different electronic components.
