Underwater Connector

What Is an Underwater Connector?

Underwater connectors are components that transmit signals or power in underwater environments.

They are used in submarines, underwater robots, sensors, and seabed cables, featuring waterproof coatings on metal contacts or terminals to protect against water, salt, and pressure changes. Durability and ease of maintenance are critical for their long-term operation underwater.

There are various types, including pressure-resistant connectors for deep-sea exploration, offering high resistance to corrosion, and fiber optic connectors for use in bays and offshore facilities.

Trailer Connector

What Is a Trailer Connector?

Trailer connectors link trailers to towing vehicles.

These connectors, usually mounted on the towing vehicle’s rear, convey electrical and control signals, including brake signals, to the trailer.

They often come in 7-pin or 4-pin configurations. The 7-pin is for larger trailers, carrying signals for brake lights, tail lights, turn signals, reverse lights, and trailer brakes. The 4-pin is for smaller trailers, handling basic lighting functions.

TNC Connector

What Is a TNC Connector?

Threaded Neill-Concelman (TNC) connectors are RF connectors for connecting coaxial cables.

Available in 50 ohms for low signal loss and efficient power and 75 ohms for high-quality video signals, they serve in wireless communications, cellular base stations, and WLAN equipment. Their threaded design ensures a secure connection, crucial in military and aerospace for reliability in adverse conditions.

These connectors are ideal for high-frequency use, preserving RF signal integrity up to about 11 GHz.

Test Connector

What Is a Test Connector?

Test connectors are used for testing, diagnosing, and programming electronic circuits or systems.

These connectors facilitate easy, quick connections for circuit performance evaluations, fault identification, or corrections, available in forms like pins, sockets, clips, and probes.

A key feature of test connectors is their ability to reliably facilitate measurements and tests without altering the circuit. Small pin connectors, for example, can be used on printed circuit board (PCB) test points for monitoring or signal injection.

Terminal Block

What Is a Terminal Block?

Terminal blocks are components used to connect electrical wires within circuits or machinery safely and securely.

They facilitate the physical and electrical connection of wires, offering features for easy wire attachment and removal for maintenance. Available in screw, spring, and push-in formats, each design offers different advantages. Screw connectors use screws to clamp wires, whereas spring and push-in connectors provide tool-free wire insertion.

These connectors find applications across various fields including industrial machinery, building electrical systems, and automobiles, with selection criteria focusing on durability and safety for high-power or exposed environments.

Telephone Connector

What Is a Telephone Connector?

Telephone connectors are physical interfaces connecting telephones and related equipment to the telephone network.

Types include RJ11, RJ14, and RJ25. RJ11, a 6-position 4-contact (6P4C) connector, is used for single-line analog telephones in homes and small offices. RJ14, also 6P4C, supports two lines with different wiring configurations.

For digital communication, RJ45 connectors, which are 8-position 8-contact (8P8C), are utilized for Ethernet connections and data communication.

Tee Connector

What Is a Tee Connector?

Tee connectors are used to divide a single flow in electrical circuits or piping systems into two directions.

In electrical systems, they create branching points for wiring, allowing for signal or power distribution in various directions. These connectors are crafted from materials that ensure minimal electrical contact resistance. In plumbing, they efficiently divide fluid flow, such as branching water supply lines to different areas of a home.

Their benefit lies not only in splitting the flow, but also in maintaining a consistent flow in each branch line.

RF Connector

What Is an RF Connector?

RF connectors are used to connect devices or cables for transmitting radio frequency signals.

They are essential in various devices like televisions, radios, measuring instruments, and Wi-Fi equipment, aiming to minimize signal loss and preserve frequency characteristics.

Common types include BNC, SMA, N-type, TNC, and F-type connectors. BNC connectors are preferred for low-frequency applications due to their ease of use, whereas SMA connectors, being compact, are better suited for higher frequencies. The choice of connector depends on factors such as frequency range, impedance (either 50 Ω or 75 Ω), durability, size, and installation convenience.

Wire-to-Board Connector

What Is a Wire-to-Board Connector?

Wire-to-board connectors are used to link a circuit board to a cable in electronic devices and systems.

These connectors are mounted on the circuit board, often soldered using surface-mount technology (SMT), while the cable side connector might be connected to the cable through pin insertion or crimp terminals. This setup facilitates signal and power transmission between the cable and the circuit board.

For needs requiring flexibility and durability, connectors with latching mechanisms or waterproof designs are used. For high-speed data transmission needs, connectors with superior high-frequency characteristics are selected.

Audio Connector

What Is an Audio Connector?

Audio connectors are used to connect audio equipment for the transmission of analog signals.

They facilitate connections between various audio devices or between audio devices and external systems. They are available in different types, including 3.5 mm jacks, 6.35 mm jacks, RCA connectors, and XLR connectors.

The 3.5 mm jack, often found in portable devices like headphones and speakers, is a compact stereo plug. The larger 6.35 mm jack is typically used in professional audio equipment and musical instruments. RCA connectors, with their distinctive small circular plugs, are used for transmitting stereo audio signals. XLR connectors are preferred for their ability to reduce noise in audio transmissions.
