How to choose the right industrial connector?

1. Connector type

Where connections, use, etc. These problems are the first to consider, this determines the type of the selected industrial connectors, the connector used locations (indoor, outdoor, corrosion environment, etc.) will affect whether or not to strengthen aviation plug seal or outside of the insulation noumenon cover shell, the type of connector decided to adopt what kind of terminal, And how many conductive terminals to arrange.

2. Environmental requirements

Temperature, humidity and other environmental conditions are determined by the location of the electrical connector, so the location and expected environment should be taken into account. The duration and information of other relevant storage conditions should also be included in the description of the environment for shock and vibration requirements, including those arising from shipping. And requirements for production conditions such as welding temperature and welding cycle duration.

3, electrical requirements

In the choice of electrical connector, to consider the electrical requirements of the product, and what kind of voltage and current requirements of the product, whether the connector can be well used in such electrical properties, these problems about the electrical requirements are needed to consider, in addition, we also need to consider some other electrical conditions: Resistance, allowable resistance change, millivolt drop, maximum current value, maximum voltage value, inrush current value, characteristic impedance, (voltage standing wave ratio), plug loss masking efficiency.

4, specification

Connector manufacturers may use approximately 25 test bodies (developed specifications) as a source for all or part of the test specifications for their industrial connectors. Consideration must be given to the adoption of appropriate test specifications for a particular application, including internationally applicable conditions.

5, mechanical performance requirements

What volume and coverage areas are effective for connectors, and what dimensional tolerances are allowed; How much is the plug and pull output of the terminal, the durability of the connector (plug and pull with the frequency) how? All of these factors is to consider when choosing electric connector, such as for printed circuit boards, it is important to determine the circuit boards of tolerance, it is the critical value card edge connectors, as well as the feasibility of critical for small power circuit, coating with the underlying material must specify the consistent with the signal level standard and environment.

A new industrial connectors, it is specifically designed to under the bad environment to build a solid Ethernet connection, tenacity, stronger, more than the previous connector to withstand more powerful, more the new interface is widely considered to be "connector" industry, its application is not only limited to the manufacturing industry, the connector is designed to withstand the test of the worst industrial environment.
