H25D-SS-1024-AB-9V/OC-SCS18-EX

Encoders provide a way of measuring motion by converting the motion of an object into digital information, making them one of the most popular types of components used in applications requiring precise measurement. H25D-SS-1024-AB-9V/OC-SCS18-EX is a type of incremental rotary encoder widely used in automated systems. This article will discuss the application field and working principle of the H25D-SS-1024-AB-9V/OC-SCS18-EX.

Application Field

The H25D-SS-1024-AB-9V/OC-SCS18-EX is primarily used in applications where speed and positioning accuracy are critical. The encoder can be used to monitor speed, position, or direction in industrial machinery, robotics, automotive, aerospace, food, packaging, medical, and printing applications. It is also suitable for detecting, tracking, and monitoring the rotational speed and direction of a variety of machinery, such as motors, pumps, turbines, compressors, conveyors, and gearboxes.

The high-resolution design provides greater accuracy than other encoders. It also features a higher pulse-per-revolution count and selectable resolutions that can be configured to meet specific performance requirements. It is designed for harsh industrial environments and features a range of temperature, shock, and vibration ratings to ensure reliable performance in extreme conditions.

Working Principle

The H25D-SS-1024-AB-9V/OC-SCS18-EX is an incremental optical rotary encoder that uses two independent light sources and detectors to detect differences in the reflection of light from a slotted disc. As the disc rotates, light from the two LEDs is passed through the slots in the disc and is reflected back by the photosensitive detectors. For every rotation, the encoder produces two square wave outputs that are 90 degrees out of phase with each other.

These two signals can then be processed by a processor or controller to determine the speed, position, and direction of rotation. The resolution of the encoder is determined by the number of slots on the disc. The H25D-SS-1024-AB-9V/OC-SCS18-EX has 1024 slots, resulting in a resolution of 1024 pulses per revolution.

In addition to the two output signals, the encoder also has a zero-index mark (Z-mark) that can be used to detect the position of the encoder relative to the slot array. This position can be used to set a reference point or initial starting position for the encoder. The H25D-SS-1024-AB-9V/OC-SCS18-EX also features several operational modes, such as single speed, full speed range, and frequency ramp.

Conclusion

The H25D-SS-1024-AB-9V/OC-SCS18-EX is a high-resolution incremental optical rotary encoder designed for applications that require precise measurement of speed, position, and direction. Its rugged design makes it suitable for use in harsh industrial applications and its wide range of resolutions makes it a versatile solution for various applications. The Z-mark feature and various operational modes also make it a useful tool for setting reference points and monitoring speed and direction changes.
