Other commonly known D-subs are DB15 connectors and DB25 connectors.Ĭontact us at EDAC for more information! Experience makes the difference. These are available in plastic for standard applications, or metal for industrial applications. This type of connector has built-in solder tails for easy mounting on a PCB.ĭ-Sub backshells enclose the junction between the conductors in a cable and the contacts in the connector assembly. There are also two types of PCB mounted connectors, straight or right-angle termination styles. This "rear disconnect" is useful when the pins on the device are damaged.ĭE9 DSUB CONNECTOR TERMINATION STYLES - STRAIGHT AND RIGHT-ANGLE Pins can be removed later with a tool inserted into the back of the connector. The contact is then inserted into the connector. The cavity is then crimped using a crimping tool. The crimp contacts are wired by inserting a stripped end of wire into a cavity at the back of the contact. A flat cable is pressed against the contacts, the rear of which is fork-shaped, which then pierce the insulation of all the wires simultaneously.ģ. The insulation displacement contacts (I.D.C.) are designed for automated assembly. DB-9 DSUB connector with Insulation displacement contacts (idc or i.d.c) The solder contacts have a cavity into which the stripped and tinned wire is inserted and then soldered.Ģ. They are differentiated by the method used to attach the wires to the contacts: soldering, insulation displacement or crimping.ġ.
There are at least three types of cable end D-Sub connectors. Note that there are DB9-DB25 adapters that easily convert a The DB9 connector is mainly used in serial ports, allowing asynchronous data transmission according to the RS-232 standard The smallest "footprint" of the D-Subminiature connectors. The DB9 connector (originally named DE-9) is an analogĭ-Subminiatures (D-Sub) connector family.
Serial printer cables that are used to connect computers and printers with serial port features.V.35 crossover cables, which enable enhanced data rates and increased transfer speeds.Null modem cables, which ensure connection stability between two PCs where no modem is present. The PNL9M16 16-inch IDC Serial to Panel Mount Serial Cable, features a 10-pin (IDC) motherboard header connection on one end and a panel mount DB9 male.Basic DTE-DCE cables with universal compatibility features, typically used in data terminal equipment and data communication applications.The main types of serial cable assemblies include: Industry examples include industrial automation systems, scientific instruments, point of sale technologies, consumer products and industrial circuit boards. What are serial cable assemblies used for?Īlthough serial cable assemblies have been replaced in some areas by Ethernet, wireless and USB connectorstechnologies, they are still used in applications where two devices need to connect with each other by means of serial communication protocols. Serial cable assemblies mostly use the RS-232 (Recommended Standard 232) interface specifications. Serial cable assemblies are used for data transfers between computers via serial communication protocols (data sent one bit at a time).
