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

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

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

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

Patch panels are groups of ports used to connect lines between communications and electronic devices. Connections are made manually with small patch cords, and are easier to wire than automatic switches. Wireless patch panels are also available

Modular enclosures consist of smaller components that can be assembled to create custom enclosures, often for temporary or mobile systems. These modular components are available in standard sizes and allow modular enclosures to be used for a variety of purposes

Phone jacks and plugs are connectors used with telephones. They are also known as modular jacks (female) and modular plugs (male

PCB terminal blocks are modular, insulated devices that mount on printed circuit boards (PCBs) and secure two or more wires together. Some have integral pin terminals and mount through holes in the board. Others plug into PCB-mounted pin strips

Terminal blocks are modular, insulated blocks that secure two or more wires together. Terminal blocks consist of an insulating body and a clamping device. Their flexibility allows wiring to be centralized and makes it easier to maintain complex control circuits

Ethernet cable assemblies are designed to support Ethernet, a standard protocol for the connection of computers in a local area network (LAN). Choices include 10Base-T, 10Base-2, 10Base-FL, 100Base-TX, 100Base-FX, 1000Base-T, 1000Base-LX, and 1000Base-SX.

Network media converters change the signal of encoded data from one media type to another as it is transmitted through, or between, networks.

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control. PACs are functionally similar to programmable logic controllers (PLC), but provide the advanced software features of personal computers (PC).

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies.

Filter, regulator, lubricator (FRL) assemblies are pre-packaged or modular assemblies of common configurations of air filters, regulators, lubricators, and gauges

Transient voltage surge suppressors protect against temporary excess voltage and/or current in an electrical circuit that has been disturbed.
