D4G0903N Datasheet/PDFRotary Switches
Rotary Switches are common electrical switching equipment. It is widely used in the field of industrial electronics and automation as a signal selector. The signal can be switched with the rotation of the switch. The signal switching can be divided into analog signal and digital signal. The d4g0903n rotary switch is suitable for application in both analog and digital signal switching.
The application Field of D4G0903N
The application fields of D4G0903N are mainly divided into two parts, namely industrial automation and electrical engineering.
- Industrial automation application fields include motor phase control and motor speed adjustment, as well as industrial equipment control and data acquisition.
- Electrical engineering application fields include transformer ratio measurements, auxiliary current measurements in power grid and distribution boards, as well as current response measurement in fuse boxes. It is also used in circuit breaker applications and the testing of high-speed relays.
Working Principle of the D4G0903N
D4G0903N is a continuous shaft rotary switch, which uses the rotation of the switch to control signals in industrial environments.The switch is composed of a signal selector and a contact box. The contact box consists of four signal connecting lines and four contact needles.The contact needles interact with the signal selector to produce signal switching when the rotation of the switch shaft is controlled.
The shape of the contact needles is designed in a bevel shape in order to move the contact needles smoothly in response to the rotation of the switch. The signal selector has two types, namely two-step signal selection and three-step signal selection.Two-step signal selection can only control two signal states, while three-step signal selection can control three signal states.
In terms of electrical characteristics, the D4G0903N switch has two types of contacts which are normal open type and normal close type. Normal open type contacts can be used when normally open control is required, while normal close type contacts can be used when normally closed control is required.The contact has a contact resistance of less than 0.005Ω and it can handle up to AC 125V or DC 30V.
In addition, the D4G0903N switch also has the advantages of long life and good insulation performance.The switch life is up to more than 200,000 times and the insulation voltage can reach up to>500V. All these characteristics make the D4G0903N an ideal choice for applications in industrial automations and electrical engineering.
Conclusion
In conclusion, D4G0903N is a rotary switch that is widely used in the field of industrial automation and electrical engineering. It has two types of signal selection and two types of contacts. It also has the characteristics of long life and good insulation performance, making it an ideal choice for industrial and electrical engineering applications.
