D-Sub Connectors

D-sub connectors, or D-subminiature connectors, are a type of electrical connector which has been in use in computers and other electronic equipment since the mid-20th century. They are named for their distinctive D-shaped metal shielding shells. D-Sub connectors come in various sizes and configurations, but all feature three parts; the male connector (the plug), the female connector (the jack or receptacle) and the housing which provides EMI (electromagnetic interference) shielding and mechanical protection for the delicate electrical contacts inside.

The 172-E09-201R021 is a 9-pin D-Sub connector that is well-suited for use in high-speed digital equipment. It has a maximum transmission speed of 1.5Gbps and is rated for 500V AC at 10MHz. It features a housing made of black thermoplastic with gold-plated copper alloy contacts, and is capable of withstanding temperatures between -25 and 85°C. The connector has a minimum of 2mm of clearance to minimise the risk of EMI leakage, and the plug is designed to allow for a horizontal or vertical mounting arrangement.

The working principle for the 172-E09-201R021 D-Sub connector is fairly simple. The connector has nine pins which are used to transfer the data signals from the device to the cable, and from the cable to the device. As the plug is inserted into the jack of the connector, the pins are lined up accurately so that the data signals are sent and received correctly. When the plug is removed from the socket, the pins are immediately disconnected from the contacts, effectively shutting off the data transfer. This protects the contacts and ensures that the connection is only established when it is supposed to be.

The 172-E09-201R021 D-Sub connector is a versatile, reliable and cost-effective connector that can be used in a wide variety of applications. It is commonly used in industrial and military applications where data must be transferred securely, and is also suitable for use in consumer electronics such as cameras and gaming consoles. This connector can be used to connect devices to displays, loudspeakers, keyboards and other peripherals, allowing for the efficient transfer of data among them.
