Power Entry Connectors - Inlets, Outlets, and Modules

Power entry connectors are versatile components used to transfer energy for a variety of applications. Though they all have the same basic characteristics, their intended use will determine the type of connector selected for a particular project. Connectors can be divided into three standard categories: inlets, outlets, and modules.

Inlets

Inlets, also referred to as plugs or receptacles, are the components of a power entry system that allow for the connection of an outside power source. A connector inlet can be found on electrical equipment and mounted to a circuit board to provide a connection for an external power supply. For AC/DC applications, inlets commonly have three contacts – a hot wire, neutral wire, and a grounding terminal. In some cases, the inlet will also have a switch that is used to disconnect the device from the line. Inlets are typically accessible from the outside of a casing for easy connection or disconnection.

Outlets

Outlets, commonly known as plugs, are the components of a power entry system used to connect the equipment to a power source. The primary function of an outlet is to provide a secure connection between an external power source and the equipment, allowing for the safe and reliable flow of electricity. Outlets also prevent the backflow of current, protecting the device from external current spikes or surges. Outlets are typically found on the end of a power cable and are sized according to the current/voltage load of the equipment.

Modules

Modules are components of a power entry system used to control, protect, and manage the flow of current. There are many different types of power entry modules, such as protective modules, surge protection modules, isolator modules, and monitoring modules, all of which serve a specific purpose. Protective modules are used to provide an extra layer of protection against voltage or current surges, while surge protection modules will disconnect the power line when a certain voltage/current level is reached. Isolator modules are used to “float” a circuit, isolating it from the line to protect against short circuits or heat buildup. Monitoring modules are used to measure current, voltage, and other parameters for power quality measurements and monitoring.

4320.0112 Application Field and Working Principle

The 4320.0112 is an outlet module designed for use in direct plug applications. It is a polymeric-body, IP65-rated module with a rated voltage of 250 VAC and rated current of 16A. The 4320.0112 contains locking clips that secure the outlet to the inlet or outlet housing, allowing the modules to be changed or upgraded without entirely replacing the housing. The outlet also contains a two-pole ambidextrous safety shutter that protects against accidental contact from the metal inserts when the outlet is not plugged in. The module features a dust-resistant seal and has a dielectric strength of 4,000 VAC.

Conclusion

Power entry connectors are essential components used in a variety of electrical/electronic applications. Inlets, outlets, and modules all play an important role in the efficient and safe transfer of energy from a source to equipment. The 4320.0112 is an outlet module designed specifically for direct plug applications and provides a secure locking mechanism and dust-resistant seal for reliable connection and protection against current surges.
