Terminals - Magnetic Wire Connectors 63909-1 is the worldwide standard for single-element industrial wiring applications especially useful for assembly and repairs. This standard includes the maximum amperage rating, minimum number of components and style and design of the terminals. 63909-1 is a UL-approved system to efficiently manage the requirements of a wide range of applications.

When it comes to wire connectors, terminals are a vital part of the entire system. The primary function of terminals is to ensure a secure connection between two wires, also known as conductors or cables. Terminals are essential in almost any type of wiring project, whether it’s an installation, repair, or upgrade. The 63909-1 standard defines the electrical specifications, design, size, type, and number of terminals for residential and light commercial applications.

Terminals used in 63909-1 are generally constructed with copper or brass plated with corrosion-resistant finishes like silver, tin, or gold. The contact pins of the terminals are also usually plated with various metals in order to improve their electrical conductivity and durability. When crimped, these pins form a tight seal that ensures an unbroken bond between two wires.

The working principle of the 63909-1 system is based on the use of a mechanical crimp connection. This approach offers several advantages compared to soldering, as crimped connections are considerably easier and faster to install. The crimping process also creates a more reliable and robust connection than soldering, which can become brittle and fail in high-temperature or vibration conditions. In addition, the connection is also resistant to corrosion and the terminals themselves are usually heat and water-resistant. This makes them suitable for both indoor and outdoor applications.

Terminal connection assemblies made in accordance with the 63909-1 standard are also relatively easy to inspect, as the practical design of the lugs and contact points allows a quick inspection of the connection even while still in its sealed package. Terminals made to the 63909-1 standard include both ring-type crimp connectors, as well as molex types. The molex type terminals have an additional wire-to-wire and wire-to-panel configuration, while the ring type terminals are mainly used for single wire connections.

Sealed insulation is also an important factor of the 63909-1 connector system. When connected, the terminals are crimped and then the entire connector is sealed with a thermoplastic material. This ensures a secure electrical connection and provides protection against dust, dirt, and other environmental factors. The thermoplastic material also provides an additional layer of insulation that protects against electrical shorts and overloads.

Finally, the 63909-1 system is extremely versatile and can be easily adapted to suit different industrial wiring applications. By using different styles of the terminals, it is relatively straightforward to adapt a standard 63909-1 design to specific requirements. Also, the various components can be easily replaced or upgraded if needed.
