What to consider when selecting a terminal

Consider the current rating and operating voltage of the required terminal connector

The current rating is the most important criterion for selecting a terminal connector. It is a measure of the amount of current that can flow through the mating terminal. Ideally, it is expressed in amps per circuit. It should be based on the temperature rise of the adjacent terminal, according to the given shell. The number of circuits in the body to regulate or reduce the current.

Check the space limit of the terminal connector

The size and weight of the terminal connector decreases as the available space decreases. However, their ability to withstand mating and unmatched frequency increases has increased significantly, so depending on the project and its design requirements, you may need to find more options in the terminal connector.

Verify the operating temperature range of the terminal connector

Most electrical connectors are subject to extreme conditions such as vibration and shock, while cable connectors and terminal connectors designed for extreme conditions and hazardous environments have special features that resist vibration and shock and withstand extreme temperatures. Therefore, the appropriate terminal connector can be selected according to the position of the terminal connector, the vicinity of the heat source, the operating temperature, and the frequency of the mating and uncoupling.

Confirm the reliability level of the terminal connector

Reliability is another important factor to consider when purchasing a terminal connector. However, reliability is a complex concept that depends on several factors. Accurate numbers are difficult to determine, but some connectors have specifications for average downtime. This can be used as a guide for selecting the right connector for any application.

Ensure that the terminal connector has a good environmental seal

Certain environments require the ingress of flammable or flammable gases, vapors, dust or liquids. The terminal connectors are environmentally sealed to prevent accidental splashing. Once you understand the level of security required, you can verify the IP rating number in the IP code system and see if the correct terminal connector is selected.

Terminal connector material and plating factors

Terminal materials and plating are often the last considerations, but since most terminal connectors are made of nylon plastic, they have a high flammability rating against flame continuity. Standard options available include tin, lead and gold, which are suitable for most applications. The substrates are usually made of phosphor bronze or brass because they have excellent strength and current carrying capacity even when exposed to high ambient temperatures for extended periods of time.
