DDMR43W2S

D-Sub Connectors are a kind of electrical connectors that are generally used in computer and data communication equipment. The most common connections are male-female, male-male and female-female, which provide a variety of connection solutions. DDMR43W2S is a male terminator, one of the D-Sub Connectors, with 43W2S as its model name.

Application Field of DDMR43W2S

DDMR43W2S is mainly used for connection between computers, medical instruments, peripheral equipment and other equipment. The main functions are signal transmission, communication, control, information exchange and other functions. DDMR43W2S is widely used in the fields of industrial automation, financial securities, medical equipment, test equipment, data communication, aerospace, automotive, home appliances and other industries where multiple connectors are needed.

Working Principle of DDMR43W2S

The working principle of DDMR43W2S is mainly based on the theory of “coupling capacitance”. First of all, the Coupling capacitance between the two connectors must be fully charged during the charging period, otherwise, no transmits can occur. Secondly during the receiving period, when the signal is applied, the charge received from the Coupling capacitance is the signal transmitted from one connector, this signal is received and recognized by the other connector.

The Coupling capacitance C is the same but the capacitance value is different. The Coupling capacitance C is determined by the distance between the two connectors. The value of C increases exponentially with the decrease of the distance between the two connectors. It needs longer charging time when the distance between the two connectors is large. At the same time, with the increase of C, the SNR (signal to noise ratio) also decreases exponentially.

Advantages of DDMR43W2S

The main advantages of the DDMR43W2S connector are its strong interference resistance and wide adaptability. The better performance of the interference resistance is mainly due to its structural design. The shielded shell prevents the interference signals from entering the connector and allows the transmitted signal more time to communicate. The wide adaptability of DDMR43W2S mainly refers to the environmental adaptability, which can work in the environment of wide temperature, humidity, pressure, vibration, dust and etc.
