Micro Connectors and Nano Connectors
Micro connectors and nano connectors exhibit contact pitches of 0.05” (micro) and 0.025” (nano), respectively. They have one or more rows of plated contacts and are either straight or right-angled. Some micro connectors and nano connectors are circular or cylindrical.
Others are designed for coaxial cables or RF and microwave applications. Both male and female devices are available. Micro connectors and nano connectors are used in a variety of industries and applications.
Military (MIL-SPEC) Connectors
Military (MIL-SPEC) connectors are shell-type connectors that 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. The type AN (Army-Navy) connector set the standard for modern day connectors. They are often referred to as Military Standard, "MIL-STD", or "MIL-SPEC" connectors.
Modular Connectors and RJ Connectors
Modular connectors and RJ connectors include two similar, yet distinct styles of connectors. Modular connectors are made of "plug-in units" that can be added together to make the system larger, improve the capabilities, or expand its size. Registered Jack (RJ) is a telephone and data jack application specific connector registered with the FCC.
Panel Interface Connectors
Panel interface connectors (PICs) are devices installed in the outside of a panel that houses a PLC, a computer, or other devices. The PIC allows the user to interface the PLC or the computer without opening the panel door avoiding potential safety hazards. Power receptacles and communication ports can be placed in a number of combinations to produce various customizable products.
PC Card Connectors
PC card connectors are used to connect PC cards, CompactFlash cards, and other devices to computers. The PC card form factor is defined and maintained by the Personal Computer Memory Card International Association (PCMCIA), a U.S. computer industry trade organization. Known originally as PCMCIA, or PCMCIA cards, PC cards were designed for computer storage expansion. They are now used as network cards, modems, and even hard disks.
Phone Jacks and Plugs
Phone jacks and plugs are connectors used with telephones. They are also known as modular jacks (female) and modular plugs (male).
RF and Microwave Connectors
Radio frequency (RF) and microwave connectors are used to connect the ends of cables in systems that operate in the radio frequency or microwave spectrum. Microwave refers to electromagnetic energy with a frequency higher than 1 gigahertz and a wavelength shorter than 30 centimeters. Radio frequency refers to alternating current that generates an electromagnetic field suitable for wireless broadcasting and/or communications if the current is input to an antenna. An RF connector can be found in transmission systems and allows for the coupling or uncoupling of system components. A mated pair consists of a plug and a jack.
Solar Connectors
Solar connectors facilitate electrical connectivity in solar energy systems. Numerous versions of connectors or standard non-connector junction boxes are employed in the solar industry and are the primary characteristic elements of solar modules.
Solenoid Valve Connectors
Solenoid valve connectors are used to connect solenoid valves and pressure switches. Solenoid valve connectors are often used as environmentally resistant junction boxes. These protective enclosures can be used with either hydraulic or pneumatic solenoid valves or pressure switches. Specific devices are capable of working with either AC or DC voltages, although some types can handle both.
Terminal Blocks
Terminal blocks are modular, insulated blocks that secure two or more wires together. Terminal blocks are used to secure and/or terminate wires and, in their simplest form, consist of several individual terminals arranged in a long strip. Terminals are useful for connecting wiring to a ground or, in the case of electrical power, for connecting electrical switches and outlets to the mains.
Thermocouple Connectors
Thermocouple connectors are used to transmit temperature readings from a thermocouple (T/C). These specialized connectors are designed to extend the thermocouple wire and must be rated for a particular T/C. Lettered choices for thermocouple types include B, C, E, J, K, N, R, S, T, and W.
