Applications

The L717HDDG78POL2C309 connector is commonly used in RS-232, RS-422, and RS-485 protocols. These protocols are used for serial communication between two or more devices over a single wire, cable, or fiber optic line. This connector is also used in negative voltage applications, as well as for low voltage applications. Common industries for this connector include industrial manufacturing, power utilities, telecommunications, and aerospace engineering.

Working Principle

The L717HDDG78POL2C309 connector utilizes four wires to transmit digital signals. The first wire is the signal wire, which carries the digital information. The second wire is the ground wire, which carries the electrical ground. The third and fourth wires are the electrical power wires, which provide energy to the device being connected. The electrical power supplied by these wires typically ranges from 12V to 48V.

The signal wire transmits digital data using voltage differences between the two states. A high voltage is used to represent a binary 1 and a low voltage is used to represent a binary 0. This data is then read by the receiving device in order to allow for communication between the two devices.

The electrical power wires are responsible for providing the energy required for communication. This voltage is typically supplied via an AC or DC power source, depending on the application. The power wires are also responsible for providing protection against electrical surges, which is necessary in order to ensure the safety of the device being connected.

The ground wire completes the connection between the two devices. Because the digital signal is carried in an alternating voltage, the ground wire is used to send the common ground signal between the two devices. This prevents the voltage from becoming too high or too low on either device, which could cause interference and damage to the device.

Conclusion

The L717HDDG78POL2C309 connector is a versatile and reliable type of D-Sub connector for digital signal transmission. This 4-pin connector is commonly employed in RS-232, RS-422, and RS-485 protocols and also works well for use in low voltage and negative voltage applications. It features a 200 Vsalt voltage rating, 105° digital signal transmission, and a 0.5A current rating. Its features and durability make the L717HDDG78POL2C309 an ideal choice for industrial manufacturing, power utilities, telecommunications, and aerospace engineering.
