D-Sub Connectors

D-sub connectors are a family of multi-pin electrical connectors used in electronic measurement, computer networking, and data communication. Named for its familiar "D" or semi-circular shape, D-sub connectors come in a selection of sizes and pin-out configurations. D-sub connectors feature two main components, the male and female, giving this type of connector its reversible design. While D-sub connectors are widely used in a variety of electronics and communication applications, the DEMMH9SZ application field and working principle are important to understand when implementing these connectors.

DEMMH9SZ Application Field

The DEMMH9SZ connector is a PCB (Printed Circuit Board) mounting connector with a 9 pin configuration, designed for use in DC current measurement and D Sub radio frequency applications. This type of connector is often used in the automotive market when connector pins are too close together and other solutions are impractical. These connectors are noted for their low contact resistance, resistance to corrosives, and compact size. As a result, they\'re a popular choice for general circuitry, device monitoring, and power connections.

DEMMH9SZ Working Principle

To begin with, this type of D-Sub connector operates on a two-piece component design consisting of a male connector (the connector with the pins) and a female connector (the connector with the sockets). The two pieces are connected through contact pins (in the male connector) and contact sockets (in the female connector). As electricity is applied, a current runs through the metal parts, energizing the circuit. This type of connection is known as a “making and breaking” connection because it is made and broken each time electricity is applied.

The DEMMH9SZ is a special type of D-Sub connector with 9 pins. Unlike some other types of D-Sub connectors that require additional hardware or wires to prevent electrical arcing, this type of 9 pin connection utilises an insulated and screened “Pigtail” that reduces the risk of electrical arcing occurring.

The 9 pins of the DEMMH9SZ offer greater flexibility, allowing it to be used for different applications like DC current measurement, bridging, serial data communication, and radio frequency heating and control. Furthermore, the DEMMH9SZ connector is also available in both 110V and 230V combinations. This makes it ideal for applications where a higher voltage is required.

Conclusion

In conclusion, the DEMMH9SZ is an important type of D-Sub connector that is used for a variety of applications. Its two-piece component design, low contact resistance, and resistance to corrosives make it a popular choice for general circuitry, device monitoring, and power connections. Additionally, the 9 pins of the DEMMMH9SZ connector offer greater flexibility, allowing it to be used for different applications. This makes the connector an ideal choice for applications where a higher voltage is required.
