male connector

A male connector is commonly referred to as a plug and has a solid pin for a center conductor. A female connector is commonly referred to as a jack and has a center conductor with a hole in it to accept the male pin. Click here for a video on the difference between male and female D-sub connectors.

BNC

In most cases BNC (alternately Bayonet-Neill-Concelman, British Naval Connector, or Barrel Nut Connector) connectors are crimped to the ends of the cable. A BNC coupler (a connector with female BNC ports at either end) allows two cables terminated with BNCs to be connected to one another. The impedance of the connector must match the cable type (50 or 75 ohm). ------------------------------------------------------ A BNC (Bayonet Neil-Concelman, or sometimes British Naval Connector) connector is used to connect a computer to a coaxial cable in a 10BASE-2 Ethernet network. 10BASE-2 is a 10 MHz baseband network on a cable extending up to 185 meters - the 2 is a rounding up to 200 meters - without a repeater cable. 10BASE-2 Ethernets are also known as "Thinnet", "thin Ethernet", or "cheapernets". The wiring in this type of Ethernet is thin, 50 ohm, baseband coaxial cable. The BNC connector in particular is generally easier to install and less expensive than other coaxial connectors

DB-9

In practice, most PCs used a male DB9 9-pin connector. The 9-pin connector supports the major data and handshake (data flow control) lines needed for peripherals such as modem or mice but does not include the "advanced" signals required for some more specialist devices.

DB-25

The DB-25 is a public connector for connecting external modems and RS-232 serial peripherals on older IBM-compatible computers. The DB-25 female connector is the parallel port connector for most personal computers. DB-25 for the first time with the original IBM personal computer (PC) with the use of long life.The female DB-25 has been widely used in the past for printer ports on PCs (see printer cables). When the serial port is popular, the male DB-25 is also the second serial port (COM2) on the PC. It is still widely used in RS-232 communication equipment.

F-type

The F-Type connector series is a high performance, cost competitive threaded connector series. Primary applications of the F-Type connectors are for cable television (CATV), set top boxes and cable modems. Amphenol's F-Type is a 75 Ω connector capable of accepting .022-.042 in. diameter conductors and complies with a 3/8-32 thread specification. The F-Type connector is a threaded alternative to the slide-on G-Type connector. --------------------------------------------------- F Type connectors are generally used for broadband, cable television, satellite television, and data & telephone applications. These connectors are used for compression fittings for cable and satellite TV installations where high frequency information is required. Our assorted collection of F Type connectors include various crimp on connectors, male and female inline couplers, crimp on coaxial connectors, right angled male/female combination adapters, couplers with washer and nut, and compression connectors. We, at SFCable aim at fulfilling all your cable and other electronic accessory requirements at one single platform. We take special care of the quality of products on offer and provide lifetime technical support for the same. All our products are manufactured by ISO 9001 - 2000 registered manufacturers to maintain the quality.

RJ-11

The smaller RJ-11 connectors are used with 2- or 3-pair UTP. Typically one pair carries the dial tone and voice circuit (also called the Tip and Ring wires after the way older phono plugs were wired). The other pair is usually unused but can be deployed for a secondary circuit. RJ-11 connectors are used for telephone systems (for example, to connect a modem to a phone jack). Note that in the UK, BT 631A connectors are used to connect equipment to analog telephone points. Modems designed for UK use come with a cable with an RJ-11 connector at one end and a BT connector at the other.

RJ-45

connectors are used with 4-pair (8-wire) cables. The connectors are also referred to as 8P8C, standing for 8-position / 8-contact. This means that all eight "potential" wire positions are supplied with contacts, so that they can all carry signals if needed. RJ-45 is used for Ethernet twisted pair cabling. ------------------------------------------------------------------

A registered jack (RJ)

is a standardized physical network interface for connecting telecommunications or data equipment. The physical connectors that registered jacks use are mainly of the modular connector and 50-pin miniature ribbon connector types. The most common twisted-pair connector is an 8-position, 8-contact (8P8C) modular plug and jack commonly referred to as an RJ45 connector.
