Connector is a kind of component that we electronic engineers and technicians often contact. It sets up a bridge of communication between the blocked or isolated circuit in the circuit, so as to make current flow and realize the preset function of the circuit. Connectors are an indispensable part of electronic equipment. If you look down the path of current flow, you will always find one or more connectors.

However, exposing common connectors to extreme conditions can degrade performance and reliability, and end users have to pay costly maintenance fees for troubleshooting and replacement parts. As a result, a new type of connector, commonly known as the "industrial connector," has been designed specifically to build a robust Ethernet connection in harsh environments that is tougher, stronger, and more resilient than previous connectors.So, how to choose a suitable industrial connector? We can consider from the following related aspects

1. Connector type

What to connect, where to use, and so on are the first considerations that determine the type of industrial connector you choose. The location where connectors are used (indoor, outdoor, corrosive environment, etc.) will affect whether the airplug is sealable or a shielding housing is added to the insulating body. The type of connector determines which terminal to use and how many conducting terminals to arrange. Of course, there are also some references to terminal technology.

2. Electrical requirements

When selecting electrical connectors, consider the electrical requirements of the product. What are the voltage and current requirements of the product, and whether the connector can be well used in such electrical properties, these electrical requirements need to be considered. In addition, we need to consider other electrical conditions: resistance, allowable resistance change, millivolt drop, maximum current value, maximum voltage value, inrush current value, characteristic impedance, VSWR (voltage standing wave ratio), plug loss and EMI shielding efficiency.

3. Environmental requirements

Temperature, humidity, and other environmental conditions are determined by the location of the industrial electrical connector and should therefore take into account the location and expected environment. What is the applicable period of other relevant storage conditions and what is the information. The description of the environment should also include requirements for shock and vibration, including requirements arising from maritime transport, and requirements for production environmental conditions such as welding temperature and welding cycle duration. The connector manufacturer indicated that the area where the highest temperature is generated is around the confluent continuous current guided by the connector.

4. Mechanical performance requirements

For industrial electrical connector, what volume and coverage area is effective; What are the allowable dimensional tolerances; What is the insertion and output of the terminal; How durable is the connector (frequency of plug and pull fit)? These are all factors to consider when choosing electrical connectors. For example, for printed circuit boards, it is important to determine the tolerance of the circuit board, which is the critical value of the flange connector, and the feasibility of achieving the critical value. For low power circuits, the coating and underlying material must be specified in accordance with the signal standard and environmental grade.

5, specification

Industrial electrical connector manufacturers may use approximately 25 test mechanisms (defined specifications) as the source of all or part of the test specifications for their connectors. Consideration must be given to the adoption of appropriate test specifications for specific application situations, including those in international use.
