D-sub connectors, also known as D-subminiature connectors, are a type of connectors used for low-speed signal transmission, with contact pins arranged in a D-shape configuration. Among them, the most widely used is the D50P91C4PX00LF series, which is widely used in the data acquisition field.

Application Field

The D50P91C4PX00LF series is mainly applied in the data acquisition field, including process control, voltage monitoring, power distribution system, telecommunications, auto-testing system, sound transmission, instrumentation, and antennae. It is mainly used to connect digital circuits, analog circuits, and even the combination of digital and analog circuits. The D50P91C4PX00LF series is widely accepted for its superior performance as compared to other series.

Working Principle

The D50P91C4PX00LF series consists of two metal shells, specifically the male shell and the female shell. The male shell is fitted with conductive pins that carry signals, while the female shell is a socket which is used to receive signals. There is also a metal shield between, which helps to reduce the impact of environmental factors on signal transmission. In order to enable signal transmission, the pins are inserted into the socket of the female shell.

Once the pins are connected, two main contact points are established which carry the signals and power from one end to other. The two points are referred to as the ground contact (GND) and the signal contact (SIG). The ground contact is normally connected to the ground at both ends and acts as a reference point for the signal. Meanwhile, the signal contact is used to transport the signal with the help of current or voltage. In order to ensure a proper connection, the two contact points should be at the same voltage or current level.

Conclusion

The D50P91C4PX00LF series of connectors are widely used in data acquisition, process control, voltage monitoring, power distribution, telecommunications, auto-testing, sound transmission, instrumentation, and antennae. This series features sturdy construction, reliable performance, and low cost. Furthermore, its two-contact points ensure a reliable connection and ensure that the signal is faithfully transmitted from one end to other. Therefore, it is highly preferred in the data acquisition field.
