Single-turn Absolute Encoder A/765
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
In demanding industrial environments, the need for precise absolute positioning without signal loss over long distances is critical for the control of heavy machinery and robots.
The A/765 Single-Turn Absolute Encoder solves this through its preset SSI interface, allowing programmable resolution up to 65536 positions and robust synchronous data transmission.
Built in an anodized aluminum housing with IP65 protection on the outlet side, it withstands radial/axial loads of 5 kg and vibrations of 5 kg. Available in guemisa.es.
- Programmable resolution up to 65536 absolute positions per revolution.
- SSI interface with preset for synchronous data transmission.
- Anodized aluminum housing with IP65 protection on the outlet side.
- Stainless steel shaft Ø10 h7 compatible with locking flange.
Technical Frequently Asked Questions
How does the A/765 model differ from the standard incremental encoder?
While incremental models require counting pulses from zero, the A/765 provides immediate absolute position upon power-up. Furthermore, it supports resolutions up to 16 bits (65536) compared to the typical 12- or 14-bit resolutions found in basic series.
What alignment precautions does the A/765 axle require?
The Ø10 h7 stainless steel shaft must be mounted with a locking flange to ensure mechanical retention. It is crucial to avoid excessive axial loads that exceed the design limits, maintaining angular alignment within UNI ISO 2768-mk tolerances.
What connectors and output options are available for the A/765?
The standard model offers a 10-pin MS310A18-1P connection with IP65 protection. An RS422 option is also available for programming and data transmission in ASCII code, as well as variants with an unbreakable disk or tropicalization as needed.
What are the environmental operating limits of the A/765?
The operating temperature is certified between -20 and +85°C, while the storage temperature can reach -30 to +85°C. The casing withstands shocks of up to 50 G (11 ms) and vibrations of 12 G in the range of 10 to 2000 Hz.
How is the SSI signal integrated with control systems?
The SSI interface transmits the position value synchronously with the clock provided by the controller. The first discrete portion of the clock stores the MSB data, and the sequence is completed up to the LSB, enabling reliable readings in high-speed systems.
