A/958S Multi-Turn Absolute Encoder
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Multi-turn Absolute Encoder, SENSORS
The ELCIS A/958S Encoder addresses the need for precise positioning in demanding industrial environments where incremental sensors fail due to noise or vibration. Its absolute architecture guarantees immediate angle readings without data loss upon system restart, eliminating homing errors and ensuring reliable detection in critical motion control applications.
The technical solution integrates a fieldbus for direct communication with modern PLCs and controllers. It utilizes Push-Pull or Parallel technology for robust signal transmission, supporting resolutions up to 25 bits in multi-turn configuration. The compact design allows for easy integration into servo-mounted axes using clamps or front screws without the need for complex external adapters.
Constructed with an aluminum housing and sealed ball bearings, it withstands radial and axial loads defined by the manufacturer to ensure mechanical durability in continuous cycles. Impact and vibration resistance ensures stable operation under severe conditions. Available in guemisa.es.
- 10÷30 VDC power supply compatible with standard industrial systems.
- Vibration resistance up to 10 G in the range of 10 ÷ 1000 Hz.
- Bearing life of 1.5 × 10⁹ revolutions at 1000 rpm.
- Push-pull 20 mA or Parallel output interface available depending on configuration.
Technical Frequently Asked Questions
What precautions should be taken during axle mounting?
Install using clamps or front screws to ensure a correct servo mount. Avoid excessive torque that could damage the internal bearings and verify the sensor's angular alignment with the motor before permanently securing the unit to prevent premature wear.
What connectors or cables are compatible with this model?
Use cables up to 1 meter long for axial connections with a maximum resolution of 25 bits and IP65 protection. For radial configurations, the cable also supports high resolutions, but refer to the 'ORDERING CODE' section to verify the specific connectors required according to your selected resolution in the order.
What are the recommended environmental operating limits?
The encoder operates between -30 and +70 °C and can be stored at temperatures from -40 to +85 °C. The maximum permissible relative humidity is 98% (no liquid state), ensuring that the internal electronics do not suffer corrosion or failure due to condensation in humid industrial environments.
