Fractional pulse rate rotary encoders are often used in conveyor and web applications to simplify control system setup. Often used to simply determine a linear displacement in baggage handling and other material handling lines, flexibility and reliability are more important than high resolution.
Historically, systems requiring fractional PPR have traditionally made use of special optical encoders, such as the Photocraft (Tri-Tronics) HS20-P and RS-P encoders with the .125AJ option. However, Posital’s IXARC programmable incremental rotary encoders offer control engineers a new option. Renowned for their ability to deliver fractional pulse rates (fractional PPR), these innovative devices can be tailored to meet the specific needs of your application.
Understanding Fractional Pulse Rates
The IXARC encoders can be configured to transmit a single pulse for more than one shaft revolution. Imagine a PPR of 0.125 – this would correspond to one signal pulse for every eight rotations of the shaft. This flexibility doesn’t stop there; the encoders can also be set up to deliver pulse rates that are not even multiples of the number of rotations. For example, a PPR of 3.5 would generate seven pulses for every two rotations. This feature is particularly beneficial in conveyor and web applications, simplifying the control system setup and enhancing efficiency.
Advanced Magnetic Sensing with Robust Protection
Posital’s IXARC encoders leverage advanced magnetic sensing technology, ensuring reliable and accurate performance. These encoders are built to last, with IP66/67-rated environmental protection. This means they can withstand harsh environments and broad temperature ranges, making them ideal for a wide range of industrial applications.
Customizable to Fit Any System
With an extensive variety of mechanical options, IXARC encoders are designed to seamlessly integrate into almost any system. Options include various shaft types and diameters, flange and casing types, materials, cable exit and connection options and levels of environmental protection. This adaptability ensures that you can find the perfect fit for your specific needs without paying for what you don’t want.
Easy Configuration with Software Parameters
One feature that does come standard is the ability to select key performance characteristics by setting software parameters via the UBIFAST programming hardware, eliminating the need for mechanical changes. Fractional pulse rates can be adjusted anywhere from 0.125 PPR to 8 PPR in steps of 0.125 PPR. Additionally, communication interfaces are programmable, offering outputs in push-pull (HTL) or RS422 (TTL) formats.
Conclusion
Posital’s IXARC programmable incremental rotary encoders are a game-changer for those seeking precision, flexibility, and durability in their control systems. With their ability to deliver fractional pulse rates, robust magnetic sensing technology, and customizable options, these encoders are designed to meet the demands of modern industrial applications. Explore the potential of IXARC encoders and take your control systems to new heights.
