Encoders: HRPG-AS16#14C Application Field and Working Principle

Encoders are a form of transducer that convert angular movement into electrical output signals. The HRPG-AS16#14C is a high-performance single-turn absolute encoder intended for industrial applications. It’s a digital optical encoder, with a 16-bit resolution giving an absolute output signal of up to 665, nm over a 360 degree circle.

Applications

The HRPG-AS16#14C is typically used in industrial motion control systems, such as machine tool and packaging machine automation, and can provide an absolute feedback signal to the motion control system without requiring calibration or homing. It’s suitable for both open-loop and closed-loop control systems, providing high accuracy and low latency, and is also suitable for use in safety applications, as it can provide a failsafe position value if power is lost.

Installation and Mounting

The encoder should be installed in a clean, dry environment, without any excessive vibration or ambient temperature changes. It should be mounted to a flat surface, with the input shaft of the motor driving it perpendicular to the mounting surface. The encoder is also temperature sensitive, and should not be exposed to temperatures above 60 degrees Celsius.

Working Principle

The HRPG-AS16#14C works by using an optical sensor to detect a pattern etched onto the rotating disk. The optical sensor is a series of LED emitters and photodiodes placed around the circumference of the disk. When the LED emitters are activated, they light up the portion of the disk below them, and the photodiodes detect how much light is reflected back. By analyzing the pattern of signals received from the photodiodes, the angle of the shaft can be determined.

Structure

The HRPG-AS16#14C is made up of four main components: the encoder body, the rotating disk, the LED emitters, and the photodiodes. The encoder body is a sealed, dust-proof housing that contains all the electrical components. The rotating disk is machined from a single piece of metal and is attached to the output shaft of the motor. The LED emitters and the photodiodes are mounted on the body of the encoder.

Benefits

The main benefit of the HRPG-AS16#14C is its high accuracy and repeatability. The 16-bit resolution results in a 0.1 degree accuracy, and the rotational life is a minimum of 15 million cycles. The optical scanning system is also resistant to shock and vibration, making it suitable for harsh industrial environments. The encoder also has a built-in redundant sensing system, which can detect any errors in the detection process and provide a failsafe position value.

Conclusion

The HRPG-AS16#14C is a high-performance single-turn absolute encoder intended for industrial applications. With its 16-bit resolution, high accuracy, and robust construction, it’s suitable for both open-loop and closed-loop motion control systems, and can provide an absolute feedback signal to the motion control system without requiring calibration or homing.
