The current industrial system contains a large number of electrical components and equipment, from PCB circuit boards, sensors, to drivers, motors, to industrial computers, electrical cabinets, and even production lines and machines... They usually need to be connected to each other. Working together. In this process, various types of industrial connectors actually play a very important role, such as: carrying power, transmitting control signals, and data communication between connected devices. It can be said that if there is no industrial connector, what is the Internet of Things, Smart manufacturing, Industry 4.0, etc., are all in vain.

Don't underestimate the industrial connector, although it is not big, the technology it contains is not simple. On the one hand, the reliability of electrical connections directly determines the performance of the equipment system; on the other hand, facing various types of application scenarios, the classification of industrial connectors is also extremely complicated. This actually brings a certain degree of difficulty to our daily product development and system integration.

So starting from this issue, we will invite Daniel, a big man in the field of industrial connectors, to help you understand the technology of industrial connectors in a simple way.

Definition and classification of industrial connectors

First of all, let's start with the definition and classification of connectors, and talk to you about the basic rules of connector product model naming.

Any electrical system must use current as a signal or energy carrier, from one conductor to another conductor through the contact between the conductor and the conductor. The contact method between this conductor and the conductor is called electrical contact, and the connector that completes this electrical contact task is the connector, which covers the three "lifelines" of "power", "signal" and "data".

To put it vividly, the connector is a "bridge" that assumes the role of current or signal connection. Although it is only a component, its role is crucial.

There is no unified classification standard for connectors so far. New application fields are constantly appearing, and the structure is becoming more and more diversified. It is difficult to use a fixed pattern to classify and name. Nevertheless, some basic classification principles are still valid, let's first understand the prerequisites for connector classification.
