DE9P1A0NA191K87 application field and working principle

D-Sub connectors are a type of electrical connector commonly featuring multiple parallel rows of pins or sockets surrounded by a D-shaped metal shield. The shield is designed to provide robust mechanical anchoring and improve the connector\'s performance in terms of EMI and RFI protection and strain relief. DE9P1A0NA191K87 refers to a specific type of D-subminiature connectors, which is suitable for signal or data transmission.

Application Field

D-subminiature connectors are widely used in industrial instrumentation systems, coin-operated amusement machines, and the automotive industry. Fewer types of pins than the standard D-sub connectors, DE9P1A0NA191K87 connectors are the most commonly used connector in industrial instrumentation for analog and digital I/Os. It has small and lightweight design, high density, and is designed for high-speed data transmission. Commonly used for applications in military, aerospace, automotive, industrial, telecommunication and medical industry.

Working Principle

The working principle of the DE9P1A0NA191K87 connector is the same as other types of D-sub connectors: it requires two identical connectors – a male connector and a female connector. Both ends of the cables are equipped with the corresponding connectors, and then the male and female connectors are connected together to achieve the signal connection, in order to complete the electrical connection required by the equipment. When the male and female connectors are connected, the locking fingers on the inner wall of the plugs enter the teeth on the outer wall of the contacts, which firmly clasps the cables, making them stable during transmission.
