DB121073-151

D-sub connectors are a very popular type of connector used in the electronics industry. The DB121073-151 is a D-shaped backshell and hood assembly that is specifically designed for some specific applications. This section will discuss the various applications and working principles of the DB121073-151.

The most common application of the DB121073-151 is for harsh environment uses. This type of connector is often used on computer back panels, or in military applications where the environment is very rugged. The backshell and hood provide a strong connection that is less likely to fail due to vibration or extreme temperatures. The connector also features low-profile terminals that are resistant to EMI/RFI interference, ensuring secure and clean data transmission.

The DB121073-151 is also commonly used in medical equipment. It is designed with a low profile, which allows for easy installation and fits in tight spaces. It is constructed from high quality materials that are capable of withstanding tough medical applications. The terminals are also double insulated to protect the internal wiring from electro-static discharge. The connector also features a high-temperature range design, which allows it to be installed in high temperature environments.

In addition to the applications mentioned above, the DB121073-151 is often used in both signal and power applications. It is highly cosponsored and rated for up to 6 amps. It also comes with a range of different terminations, including standard signal, power, and supplementary contacts. This makes it an ideal connector for mixed signal applications.

The working principle of the DB121073-151 is quite simple. The connector is designed to provide a secure connection between two points and prevent against current or voltage loss. This is achieved by two features: the backshell and the hood. The backshell is held securely in place, and the hood is designed to resist EMI/RFI interference. The two pieces are then connected using small screws or fasteners, which hold them together securely.

It is important to note that the DB121073-151 is not recommended for high temperature applications that exceed 150° C. The material may be degrading if exposed to such high temperatures. Additionally, the connector should be handled with care and should not be subject to excessive force or stress, as this could cause the connection to become unstable or make it more prone to failure.

In conclusion, the DB121073-151 is a D-shaped backshell and hood assembly that is ideal for applications in military, computer back-panel, medical and signal/power applications. It is constructed from durable and high quality materials and comes with a range of terminations. The backshell and hood provide a reliable connection, while the terminals are double insulated and provide protection against EMI/RFI interference. However, it should not be used in applications with temperatures above 150° C.
