Airtac magnetic coupling rodless cylinder RMT structure principle and stroke table
Introduction of Airtac rodless cylinder RMT (guide rod type)
The device adopts a magnetic coupling rodless cylinder design, and there is no mechanical connection between the piston and the slider. Therefore, the airtightness of Airtac cylinder RMT will be more excellent.

Universal Circuit Breaker CW3X Selection Parameters and Protection Function
Overview of universal circuit breaker CW3X
CW3X series universal circuit breakers are mainly used in various low-voltage power distribution fields. They can not only protect lines, but also protect electric motors and generators.
Starting method and precautions of solid state soft starter
The solid-state soft starter is also a kind of soft starter. What is the difference in the starting method of this kind of instrument when it is in use? Here is a brief explanation for everyone.
The choice of electromagnetic relay, its working principle and wiring method are explained in detail
Electromagnetic relay is a common electrical appliance in industrial circuits. Many people do not understand the choice of electromagnetic relay very well. There are many questions about how to choose a good electromagnetic relay. So how to choose electromagnetic relay?
How to choose the power relay correctly, which is divided into 4 steps, I hope it will be helpful to everyone's study.
1. Measuring contact resistance
Use the resistance file of the universal meter to measure the resistance of the normally closed contact and the moving point. The resistance value should be 0, (the contact resistance can be measured in a more accurate way within 100 milliohms); while the normally open contact and the moving point The resistance of a point is infinite. It can be distinguished which is a normally closed contact and which is a normally open contact.
The principle and precautions of the relay drive circuit. The application of relays is becoming more and more extensive. The role of relays is mainly used to control current. At present, the common relays include general relays, automotive relays, power relays, etc. We will inevitably encounter Encountered all kinds of problems, such as the principle of the relay drive circuit and precautions, let me explain it to you.
