Single-turn Absolute Encoder A/359Z
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
The A/359Z Single-Turn Absolute Encoder addresses the critical need for precise positioning without external sensors in stepper motor and servo control applications. It eliminates the uncertainty of incremental counting by providing a single, stable position from power-up, ensuring the repeatability required in industrial machinery.
The technical solution integrates a phototransistor optical sensor with a long-life LED light source. It offers a maximum resolution of 8192 positions using standard parallel code, allowing direct integration with digital controllers without the need for additional conversion or complex external circuitry.
The construction utilizes an anodized aluminum housing with IP65 protection at the output, ensuring vibration resistance of 12 G and continuous operation up to 6000 RPM. The hollow through-shaft made of stainless steel allows direct mounting to motors via spring coupling or stop collar, available in guemisa.es.
- Standard parallel output for direct integration with digital controllers without the need for additional conversion.
- Anodized aluminum casing that guarantees durability and heat dissipation in demanding industrial environments.
- Hollow through shaft made of stainless steel compatible with spring couplings for direct mounting on engines.
- Vibration resistance of 12 G and continuous operation up to 6000 RPM without loss of absolute accuracy.
Technical Frequently Asked Questions
How does the 359Z model differ from the 359ZM model of the same series?
The 359Z model is similar to the 359ZM but without the included coupling; it is supplied specifically with a stop collar for mounting on the motor shaft. Both share the maximum resolution of 13 bits and the anodized aluminum housing, but the Z requires direct mounting using its collar.
What alignment precautions are required for the Encoder's through-shaft hollow shaft?
The hollow stainless steel shaft must be free of obstructions and properly aligned with the motor to prevent excessive radial loads. It is recommended to verify that the stop collar or spring coupling does not introduce additional friction that could affect the service life of the ball bearings.
What connectors and output options are available for the interface?
The standard configuration includes a 10 mA open collector NPN output. Gray code is the default parallel format, but custom options are available for specific electronic interfaces depending on the requirements of the integrated control system in the project.
What are the device's environmental and thermal operating limits?
The A/359Z Single-Turn Absolute Encoder operates within a temperature range of -30°C to +85°C. Its thermal resistance up to +75°C allows for a 72-hour lifespan, while IP65 protection ensures dust and splash resistance in harsh environments.
How is the parallel output signal integrated with modern control systems?
The parallel interface displays the angular value directly on the connector pins, proportional to the selected resolution. This configuration allows direct reading by microcontrollers or PLCs without the need for additional decoders, simplifying the implementation of absolute position control logic.
