Introduction to SWR25A-NREC-S07-RB-BR Rectangular Connectors - Headers, Male Pins

SWR25A-NREC-S07-RB-BR connectors are a type of rectangular connectors used in electrical applications, primarily for interfacing two wires. The acronym “SWR” stands for “Starting, Wiring, and Routing”, denoting the use of these connectors to route electrical signals and power supply wiring. The “25A” section of the name indicates that the connectors are rated for up to 25 Amps, making them suitable for higher-power applications. The “NREC-S07” section specifies the dimensions of the connectors - these have a 4.2mm wide housing and 7.2mm pin pitch, making them suitable for connecting to both round and flat receptacles. The “RB-BR” section of the name indicates that the connectors have a red body and black pins.

Application Fields of SWR25A-NREC-S07-RB-BR Connectors

These connectors are typically used in applications where high-power connections are required to be routed between a source and various destinations. This is usually done so that the signal and power currents are kept separate and distinct - failure to do this could lead to damage to the electrical equipment used in the application. Some of the most common uses of these connectors include industrial automation equipment, machine-to-machine communication, HVAC systems, lighting systems, communications and data networks, and more.

Working Principle of SWR25A-NREC-S07-RB-BR Connectors

These rectangular connectors are typically used with spring-loaded contact systems - this ensures that a steady and reliable connection is maintained between the pins and receptacles. The connector is a simple slide-in installation - the connectors are pressed firmly into place to create a reliable connection, and when removed, the springs pull the pins away from the receptacles. The springs also help protect the pins from accidental contact, as well as preventing dirt and dust from entering and damaging the connection. The contacts are also coated with an electrolytic layer for extra protection against corrosion.

Other Features of SWR25A-NREC-S07-RB-BR Connectors

In addition to the benefits of the spring-loaded contact system, these connectors are also designed to be vibration and shock-resistant. The insulator is made from a tough plastic polymer, with a reinforced nylon body to reduce contact damage. The early-break contact design prevents short circuits, and the pins are recessed into the socket to reduce accidental contact. This makes them suitable for a wide range of applications, and helps to protect any connected electrical components.

Conclusion

The SWR25A-NREC-S07-RB-BR connectors are a versatile and reliable type of rectangular connector suitable for a variety of electrical applications. The combination of a high-amp rating, spring-loaded contact system, vibration and shock-resistant design, and recessed pins make these connectors a popular choice for high-power routing between multiple sources and destinations.
