Types of Encoders

Encoders are an important type of transducers used in industrial and commercial applications. The main purpose of encoders is to measure speed and position of machinery and objects. There are two main types of encoders: absolute encoders and incremental encoders.

Absolute Encoders

Absolute encoders are typically employed in applications where precise positioning is necessary. They provide instantaneous position data and hold the position even after power is lost or cut. These encoders use a pattern of movable conductors and stationary contacts to determine direction and position. The signals generated by an absolute encoder are binary coded. PEC12R-4217F-N0024 is an example of an absolute encoder.

PEC12R-4217F-N0024 Application Field and Working Principle

The PEC12R-4217F-N0024 is a high-performance absolute encoder that can be used in applications requiring precise positioning. It has a 17-bit absolute value output, with a resolution of 17 bits. This makes it suitable for applications that need fine movement detection. The encoder operates at a maximum speed of 5,000rpm.

In terms of working principle, the PEC12R-4217F-N0024 encoder is equipped with two absolute position detectors, which measure the rotation angle of the shaft. The position detectors generate signals which are then interpreted by the encoder logic circuit. This logic circuit generates the absolute position signals for each passage of the position detector. The signals are then binary coded and transmitted to the connected device.

Incremental Encoders

Incremental encoders are the most common type of encoders used in industry. They are used in industrial applications where only relative position is required. They generate digital pulses based on a rotary or linear motion. The pulses generated by incremental encoders are in the order of quadrature signals, which represent both position and direction. These encoders are relatively less accurate than absolute encoders, but they are much more cost effective and simpler in construction.

Conclusion

In conclusion, encoders are transducers that measure speed and position in industrial and commercial applications. There are two main types of encoders: absolute encoders and incremental encoders. PEC12R-4217F-N0024 is an absolute encoder that is suitable for applications requiring precise positioning. It consists of two absolute position detectors and a logic circuit to generate the absolute position signals. Incremental encoders, on the other hand, generate digital pulses in the order of quadrature signals, representing position and direction, but they are less accurate than absolute encoders.
