Precision Connector & Switch

Types of Electrical Connectors

A connector is an electronic component that works by joining the ends of the connector into their respective device to create an electrical circuit within the device. Connectors allow for a secure electrical connection to either a wire, a printed circuit board, or another connector.

At E2, we carry a wide selection of connector types, such as Automotive, Backplane, Power, D-Sub, Fiber Optic, Circular, Modular / Ethernet, Terminal Blocks, and more. Whether your industry requires commercial-grade or military specification (MIL-SPEC), you can browse TTI to find the right connector for your electronic design. We stock high-quality electronic components from trusted manufacturers like Amphenol, Aptiv, ITT Cannon, Molex, Phoenix Contact, and TE Connectivity.

Circular Connectors

Ethernet/modular connectors are found in nearly all industries where small pin count connections (generally 8 or less) are needed. They are most widely used in telecommunications applications with the most obvious example being their use in modular telephones to connect cords, handsets, etc. Crimp, solder, and insulation displacement are the most common methods of termination for these devices.

D-Sub Connectors

D-subminiature connectors (D-subs) have rectangular shells with D-shaped mating faces. Plug connectors hold pin contacts while receptacle connectors hold socket contacts. The mating face provides polarization to prevent mismating, while the shell of the connector provides rugged protection for otherwise exposed pin contacts.

Ethernet & Modular Connectors

38999 (a type of circular connector) is one of the most popular connector series for modern military applications, and it is becoming more prevalent in high tech commercial applications such as telecommunications base stations.

IC & Component Sockets

Some applications require that integrated circuits (IC's) and IC chips be placed on a PC board in such a manner that they can be easily plugged in or removed. To accomplish this, IC sockets and chip carriers are used. SIP and DIP sockets, Pin Grid Arrays (PGA's) and Plastic Leaded Chip Carriers (PLCC's) are the most common socket products used.

RF Connectors

RF connectors are used to transmit signals from point to point with minimal energy loss while reducing noise. They can be used for DC and audio frequency signals when effective shielding is desired and are used to transmit radio frequency energy up to 18 billion cycles per second.

Terminal Blocks

Terminal blocks are modular, insulated blocks that connect two or more wires together. They provide a secure connection point for electrical wiring and are commonly used in industrial control panels and electrical distribution systems.

Terminals

Electrical terminals are devices designed to connect electrical conductors together. They come in various forms including ring terminals, spade terminals, butt connectors, and quick disconnect terminals, each serving specific connection needs in electrical systems.
