Modular connectors are molded plastic connectors used to interconnect electronic devices and appliances through wires. They have several advantages over other systems, modular plugs are assembled in a single step, are easily coupled and decoupled using a plastic latch and are rather inexpensive. They were first introduced for telephony applications (4P4C RJ-11) but are also commonly used for ethernet networking (8P8C RJ-45).
