Terminals - Ring Connectors are generally used in various industries to provide secure and reliable connection between cable and electrical equipment. The 51989-2 standard designates a form of terminal connector with the technical specifications and dimensions for application in non-shielded, non-equipotential applications.In the 51989-2 standard, the ring terminal consists of a male or female threaded stud section, a terminal base, and a pair of contact pins. The terminals are available in different sizes and can be used for mating and crimping to both insulated and uninsulated wire of various sizes. The nuts provided with the terminal allow for secure attachment.The 51989-2 terminals must meet the thermal, electrical, and mechanical requirements in order to be effective and reliable. The standard requires the connectors to be flame-resistant and to hold up to a temperature range of 0-95°C. Additionally, these connections should have an electrical current rating up to 100A, a minimum voltage insulation rating of 300V, and a minimum contact resistance of 5 mΩ. The mechanical endurance of the terminal should exceed 5,000 insertion and withdrawal cycles.The application of 51989-2 terminals is quite wide. The ring terminals with suitable external components can be used as reliable connecting elements in the user’s terminal connection blocks, junction boxes, and power distribution centers. They can also be used to connect devices such as motors, actuators, sensors, switches, relays, and others. Additionally, these terminals can also be used in the field of robotics and automation control systems.The working principle of a 51989-2 terminal is relatively simple. The connector is fully insulated and then inserted into the terminal connection block. The connector is then secured with the nuts provided to ensure a good physical and electrical contact between the pins and the terminal connection block.Once the connection is made, it is important to ensure that the connection is free of corrosion or oxidation, which can affect performance and/or create a safety hazard. The connections should be periodically checked for proper electrical engagement and resistance values.51989-2 terminals provide a reliable and secure connection between cable and electrical equipment, and are a great option for reliable and safe electrical connections. The standard requires the terminals to meet rigorous mechanical and electrical standards, and they are suitable for use in a wide range of applications. With this in mind, these terminals are an ideal choice for both industry users and hobbyists.
