Technical Frequently Asked Questions
How does the A/380S model differ from incremental encoders in terms of data output?
The A/380S offers immediate absolute positioning without the need for a mechanical shoulder, unlike incremental models that require counting from zero. It supports Gray, Binary, and BCD codes for direct integration with standard PLCs, facilitating reading in modern control systems without data loss.
What alignment precautions does the A/380S shaft require during installation?
The stainless steel spindle requires precise radial alignment to prevent excessive lateral loads on the sealed bearings. Specialized assembly tools are recommended to avoid damaging the optical disc surface or the output connector, ensuring mechanical integrity.
What connectors and output options are available for the A/380S?
IP65/IP66 connectors with 10 to 26 pins are available depending on the interface (Parallel, SSI, or Analog). Outputs include standard NPN Open Collector and Push-Pull for 1- to 12-bit resolutions, as well as shatterproof disk options for harsher environments.
What are the environmental operating limits of the A/380S under extreme conditions?
It operates stably between -30 and +85 °C with shock resistance of 50 G (11 ms). Specific versions are available for high temperature, low temperature, or tropicalization if the operating environment exceeds the standard datasheet ranges, ensuring reliability under extreme conditions.
How does this Absolute Encoder integrate with control systems that require an analog signal?
Interface (A) allows for a current output of 1–20 mA or a voltage output of 0–10 V proportional to the angle value. For Gray and Excess codes, transmission is via RS422, controlled by an external clock, for maximum data integrity over long distances within the system.
