Power Entry Connectors - Inlets, Outlets, Modules

Power entry connectors are specialized electrical connectors used to interface electrical circuits to an external power source. They can be found in a wide variety of applications, from computer panels to automobiles. The 1-208979-4 series is a type of power entry connectors, specifically designed for outdoor weather-proof applications. This article will discuss the general application field and working principle of the 1-208979-4 series.

Application Field

The 1-208979-4 power entry connectors are primarily used to connect electrical circuits to an external power source in outdoor weatherproof conditions. Such conditions often include exposure to rain, wind, heat, and strong sunlight, and the 1-208979-4 connectors are designed to resist these environmental conditions. This series of power entry connectors is suitable for applications such as outdoor lighting, security systems, HVAC (heating, ventilation, and air conditioning), and swimming pool pumps. They are also suitable for industrial environments, such as factories, where they can be used to connect electrical circuit boards to an external power source.

Working Principle

The 1-208979-4 power entry connectors are constructed from PVC housing and brass-plated contacts. The housing is designed for use in extreme weather conditions, and the contacts are plated in brass for extra strength. The connectors use screw-type threaded fasteners to securely attach the housing to the electrical enclosure or panel. An O-ring seals the connection to provide weatherproof protection. The contacts are designed for use with wires up to 16 AWG (American Wire Gauge) in size, and the connectors have an integrated strain relief to protect against cable strain. The connectors are also UL (Underwriters Laboratories) and RoHS (Restriction of Hazardous Substances) approved for safe and reliable operation.

In order to use the 1-208979-4 series power entry connectors, the contacts must be first attached to the electric enclosure or panel. The contacts must then be connected to the power source via the appropriate cables, and the cables must be fed through the O-ring sealed housing. The housing can then be securely fastened to the electric enclosure or panel using the screw-type threaded fasteners.

Conclusion

The 1-208979-4 series of power entry connectors are designed for outdoor weatherproof conditions, and are suitable for a wide range of applications. They use a combination of PVC housing, brass-plated contacts, and O-ring seals to protect against the environment, and they can easily be attached to electric enclosures or panels. They are UL and RoHS approved for safe and reliable operation, and are suitable for use with wires up to 16 AWG in size.
