Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices

Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection

Modular connectors and RJ connectors are plug-in units used in many networking and telecommunications applications. Registered jack (RJ) connectors are a type of modular connector, which often have protective capabilities such as integrated filters to protect against unwanted signals or some type of magnetics to provide filtering, signal conditioning, and isolation

Coaxial connectors are composed of an insulated central conducting wire wrapped in another cylindrical conductor (the shield). The cable is usually wrapped in another insulating layer and an outer protective layer. Coaxial cables and connectors have the capacity to carry vast quantities of information. They are typically used in high-speed data and CATV applications

Military (MIL-SPEC) connectors are built in accordance with military specifications. Their design takes into account the need to protect the connection from environmental factors, allowing them to be used in military and aerospace applications. 

Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or other fiber optic device

DIN connectors are high frequency, multi-pin, electrical connectors that meet standards established by Deutsches Institut für Normung (DIN), a German national organization for standardization. The ends of DIN connectors are round, notched, and protected by a metal skirt to ensure that pins line up correctly

Circular connectors are multi-pin connectors primarily used for external interfacing

Audio amplifiers are used in circuits and systems to process audio signals

Wire and connector assembly and installation tools are used to assemble and install connectors

USB connectors are used with universal serial bus (USB) ports. They can be used to connect USB products together, or to connect USB wires and peripherals to other standard port types

Audio transducers and buzzers are used in electronic equipment, toys and various warning devices as the sounding component

Audio transformers are involved in the transmission of voice or sound signals. They often require wide frequency bandwidth with low distortion and noise suppression

Video, audio, and multimedia chips are IC chips designed for video, audio, and multimedia applications

Digital audio systems electronically record and store audio signals such as voice, music, alarm, and security messaging for broadcast, editing, monitoring, and playback
