Unveiling the AVAGO Three Channel Optical Incremental Encoder Modules HEDS 9000/9100, a marvel of high cost performance, engineered to redefine precision and reliability.
Product Description
The HEDT-9040 and HEDT-9140 modules are designed for high temperature environments, ensuring robust operation and durability.
These sophisticated three channel optical incremental encoder modules deliver exceptional performance.
Engineered for affordability, these modules, paired with a codewheel, precisely detect rotary position with unparalleled accuracy.
Each module is crafted from a high-quality lensed LED source and detector IC, all encased in a compact, resilient plastic package.
The design features a state-of-the-art lensed LED source and a precision detector IC, housed within a durable and compact plastic enclosure.
Thanks to a meticulously collimated light source and an innovative photodetector array, these modules deliver the outstanding performance synonymous with the HEDS-9040/9140 family.
This sophisticated technology guarantees the exceptional performance of the HEDS-9040/9140 three channel encoders.
The HEDT-9040 and 9140 modules include a comprehensive Block Diagram with two channel quadrature outputs plus a third channel index output.
These outputs are designed to provide precise and reliable signal processing.
The HEDT-9040 and 9140 feature two channel quadrature outputs complemented by a third channel index output for advanced encoding.
This third channel delivers a 90 electrical degree high true index pulse, enhancing processing accuracy.
The index output emits a precise 90 electrical degree high true index pulse, ensuring superior accuracy.
This ensures precisely timed high true index pulses for optimal performance.
Designed for codewheels, the HEDT-9040 caters to an optical radius of 23.36 mm (0.920 in.), providing adaptable performance.
Meanwhile, the HEDT-9140 is specifically tailored for codewheels with an optical radius of 11.00 mm (0.433 in.), offering versatile applications.
The innovative design of the HEDT-9140 accommodates codewheels with a smaller optical radius of 11.00 mm (0.433 in.).
This ensures seamless functionality across a range of optical radii.
Access the precision of quadrature signals and index pulse via five 0.025 inch square pins, thoughtfully positioned on 0.1 inch centers.
These pins ensure robust connectivity and signal integrity.
The strategic layout of the pins guarantees reliable access to signals and pulses.
Selectable resolutions range from 360 to 1024 counts per revolution, with tailored solutions available through Avago sales representatives for diverse requirements.
For bespoke resolutions, consult our local Avago experts, who are eager to assist.
Our team is always ready to discuss and provide custom resolutions to suit specific needs.
