The AVAGO Heds 9000/9100 series offers an impressive blend of three-channel optical incremental encoder modules, known for their exceptional performance at a high cost efficiency.
Product Description
Introducing the HEDT-9040 and HEDT-9140, these modules are engineered to excel even under extreme high-temperature conditions.
Each module is a sophisticated three-channel optical incremental encoder solution, designed to meet the demands of precision-driven industries.
When paired with a codewheel, these budget-friendly modules deliver precise rotary position detection.
The core of each module features a lensed LED source combined with an advanced detector IC, all encased in a compact plastic package.
This clever design integrates a powerful LED source and a precision detector IC into one compact, plastic-encased unit.
By utilizing a meticulously collimated light source and an innovative photodetector array, these modules offer unparalleled performance.
This innovative design ensures that the high performance of the HEDS-9040/9140 encoders is mirrored in the HEDT modules.
They deliver the same outstanding high performance as the HEDS-9040/9140 three-channel encoders, thanks to their advanced design.
With the HEDT-9040 and 9140, you'll find a robust block diagram featuring two-channel quadrature outputs, plus a precision third-channel index output.
The HEDT-9040 and 9140 modules boast a comprehensive block diagram that includes two-channel quadrature outputs and a third index channel.
The third-channel index output is characterized by a 90-degree electrical high true index pulse, ensuring precise signal accuracy.
This index output delivers a 90-degree high true index pulse with impeccable electrical precision.
This index pulse stands out for its precision, offering a 90-degree high true index.
The HEDT-9040 is expertly crafted for codewheels with an optical radius of 23.36 mm (0.920 in.), making it ideal for specific applications.
Meanwhile, the HEDT-9140 is tailored for codewheels that boast an optical radius of 11.00 mm (0.433 in.), enhancing versatility.
The HEDT-9140, on the other hand, is designed for codewheels featuring an optical radius of 11.00 mm (0.433 in.), offering adaptability.
Its counterpart, the HEDT-9140, is optimized for codewheels with a refined optical radius of 11.00 mm (0.433 in.).
Accessing the quadrature signals and the index pulse is streamlined through five 0.025 inch square pins positioned on 0.1 inch centers.
The quadrature signals and index pulse are conveniently accessible via a set of five 0.025 inch square pins, strategically placed on 0.1 inch centers.
These signals are accessed through an intuitive array of five 0.025 inch square pins, arranged on 0.1 inch centers for easy connectivity.
Available resolutions range from 360 to 1024 counts per revolution, allowing for customizable precision to suit diverse applications.
For other resolution needs, we recommend contacting your local Avago sales representatives to explore a wider range of options.
We encourage you to consult with Avago sales representatives for additional resolutions that can be tailored to your specific requirements.
