D-Sub connectors are popular and classic in the network hardware space, from which 3-1740199-2 is one type. This product offers more reliable connections for data transmission, avoiding signal loss and instability. With the advantage of being robust and durable, these connectors are commonly used in many embedded data transmission applications, such as in radiography equipment, instrumentation, motion control and communication systems.

The 3-1740199-2 belongs to the D-Sub category. It has a 2-row, 9-pin configuration and a range of standard features built in, including a combination thumbscrew/cage clamp termination, a mating cycle life of 500 cycles, and a contact current rating of up to 5 amps. It creates an electrically and physically secure connection between the two D-sub components connected together. It also uses a low profile mate/unmate force to ensure optimal contact while still providing mechanical stability for the connection.

The 3-1740199-2’s working principle is based on the standard D-Sub pin architecture with multiple pins using the guidance of an alignment key and a pin detection mechanism. These two features help correctly align the 2 D-subs when they are being mated. This alignment process helps ensure that the two sets of pins of the mating D-Subs achieve a complete connection. Furthermore, the 3-1740199-2 uses a dual-contact pin design that helps reduce contact resistance and conductivity. This is achieved by designating one of the two pins as a power pin, while another pin is a ground pin.

The application range of the 3-1740199-2 is wide as it is widely used for multiple data points or small low speed data applications such as analogue signals. These connectors can be used in a variety of telecommunications fields such as radiography imaging systems, radio communication systems, industrial plant monitoring systems, cable television system, Internet access, and cellular networks. Besides, it’s also commonly used in sensors, switches and buttons, automobile control systems, instrument control systems, medical and industrial monitors, signal conditioning, and digital logic devices.

In conclusion, the 3-1740199-2 is a well-designed and reliable type of D-Sub connector. Its combined features including the 2 row, 9 pin configuration, combination thumbscrew/cage clamp termination, 500-cycle mating cycle life, and 5 amp contact current rating makes it an ideal choice for many embedded data transmission applications. The utilization of the two alignment keys and pin detection mechanism in the connecting process not only ensures the reliability of the connection, but also reduces contact resistance, allowing it to be used for many different applications.
