Single-turn Absolute Encoder A/363
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
In demanding industrial environments where positional accuracy is critical, incremental sensors fail in the event of power outages or severe vibrations. The A/363 Single-Turn Absolute Encoder guarantees immediate status readings without requiring a mandrel cycle after each stop, eliminating downtime during startup processes.
The internal architecture integrates phototransistors and an LED light source with a lifespan exceeding 100,000 hours, ensuring long-term stability. It supports configurable resolutions from 2 to 13 bits (8192 positions) with multiple output codes such as Binary, Gray, or BCD, adapting to various control architectures without data integrity loss.
Constructed from an anodized aluminum body with a square flange, it withstands radial and axial loads up to 50G. Operating between -30 and +85 °C, its compact size 25 design allows for direct integration into heavy machinery. Available in guemisa.es.
- Anodized aluminum metal housing with square flange for heavy industrial applications.
- Bearing life of 1.5 x 10^9 revolutions under load of unbreakable disc.
- IP65 protection on the outlet side and shaft, with IP66 option via specific connectors.
- Maximum operating frequency up to 50 kHz for fast digital signals.
Technical Frequently Asked Questions
How does the A/363 model differ from standard incremental encoders?
Unlike incremental models that require a reference pulse after each power outage, this absolute encoder maintains the internally encoded position. This allows for immediate reading upon system restart without the need to manually find the mechanical zero point.
What assembly precautions are required for the A/363 shaft?
The stainless steel shaft withstands radial and axial loads up to 50G under impact conditions. It is crucial to ensure that the coupling alignment does not exceed torque limits to prevent damage to the bearings, which are certified for a lifespan of 1.5 billion revolutions.
What connectors and output options are available for the A/363?
The device offers standard parallel, analog, or digital SSI interfaces. Options include push-pull outputs with PTC, line driver, and open collector NPN outputs, allowing it to be adapted to existing PLC logic without the need for complex external circuitry.
What are the environmental operating limits for the A/363?
The operating and storage temperature range is between -30 °C and +85 °C. The device has passed burn-in tests at +75 °C for 72 hours, guaranteeing thermal stability in environments with severe fluctuations without LED degradation.
How does the A/363 integrate with modern control systems?
It supports resolutions up to 13 bits (8192 pulses) and Gray or Binary codes for maximum compatibility. The output can be configured as analog current or voltage, facilitating direct connection to data acquisition cards without the need for additional converters.
