61R128-080

Encoders are commonly used components in industrial applications. The 61R128-080 is an encoder that is widely used in a variety of industrial applications. This encoder is designed to add motion or position feedback to servo and stepper motor systems, or to act as a speed or position sensor in machinery. In this article, we will discuss the application field and working principle of the 61R128-080 encoder.

Application Field

The 61R128-080 encoder is designed to be used in a variety of applications, including the following:

• Position feedback in servo and stepper motor systems
• Speed and position feedback on machinery
• As a tachometer in machine tools
• Position sensors used as limits and brakes in machine tools
• Speed measurement in industrial processes

Working Principle

The 61R128-080 encoder uses Magnetic-Resistance (MR) technology to measure motion or position. The MR technology is based on the principle that when an electrical current is passed through a coil, a magnetic field is created. When a ferromagnetic material is placed in the field, the associated electrical resistance of the material will change. The 61R128-080 encoder uses this principle to measure the position of a shaft. The encoder has a stationary part, which contains a coil and a ferromagnetic material, and a rotating part, which contains a toothed wheel. As the toothed wheel rotates, the magnetic field due to the coil’s current changes. This change in the field causes the resistance of the ferromagnetic material to change, which is measured by the encoder. The encoder then converts the resistance change into an analog signal, which can be used as an input to the servo or stepper motor system. The 61R128-080 encoder is designed for use with speeds up to 10,000 rpm and can handle temperatures between -20°C and +100°C. It is a highly versatile encoder that can be used in a wide range of industrial applications.
