Single-Turn Absolute Encoder A/790AA
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
In demanding industrial environments where positioning reliability is critical, this A/790AA Single-Turn Absolute Encoder eliminates the signal losses associated with incremental sensors. Its architecture ensures accurate readings even under severe magnetic field fluctuations or adverse mechanical conditions that typically compromise other conventional devices.
The implemented technical solution allows for flexible configurations up to 65,536 revolutions with native SSI and RS422 interfaces. It supports incremental Sine/Cosine outputs at 1024 positions, ensuring robust transmission without recalibration after power outages, vital for continuous production processes in heavy machinery or high-speed control systems.
Built with long-life bearings and a shielded housing, it withstands intense mechanical vibrations without degrading its angular accuracy. This component is designed for direct integration onto motor shafts without complex external adapters. Available in guemisa.es.
- Absolute architecture programmable up to 65536 revolutions with integrated SSI and RS422 interface.
- 1024-position incremental Sin/Cos output for applications requiring high-speed feedback.
- Armored housing with IP65 protection against dust and liquids in harsh environments.
- Direct mounting Servo-Mount optimized to reduce shaft moment of inertia.
Technical Frequently Asked Questions
What alignment precautions are required for the shaft of the A/790AA Single-Turn Absolute Encoder?
Perfect coaxial alignment of the Ø6.35mm output shaft with the motor or coupling is required. Avoid applying lateral forces to the shaft during installation to prevent damage to the internal bearings. The Servo-Mount assembly requires controlled torque to ensure the integrity of the magnetic sensor.
What connectors and output options are available for the 790AA series?
It is available with direct wiring connectors or standard DIN adapters depending on the configuration. Output options include SSI and RS422, allowing direct integration with modern controllers without the need for additional converters for differential signals.
What are the operating temperature and humidity limits for this model?
It operates in a temperature range of -20°C to +70°C with IP65 protection against dust and liquids. It is not designed for environments with humidity levels exceeding 95% without condensation or direct exposure to corrosive agents that could affect the encoder's sealed housing.
How does the A/790AA Single-Turn Absolute Encoder integrate with standard PLC systems?
It integrates via SSI or RS422 signals, compatible with standard industrial PLCs such as Siemens, Allen-Bradley, or Omron. The incremental Sin/Cos output allows direct connection to data acquisition cards for applications requiring high-speed analog feedback.
