Single-turn Absolute Encoder A/363S
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
The A/363S Encoder addresses the critical need for precise positioning in demanding industrial environments where conventional optical encoders fail due to vibration or dirt. Its metal housing and servo-mount flange ensure a robust and durable installation on heavy machinery.
This device offers configurable resolution from 2 to 13 bits (up to 8192 positions) with optical phototransistor output and a long-life LED source exceeding 100,000 hours. The interface supports parallel, SSI, or analog configurations for flexible integration into modern control systems without sacrificing mechanical accuracy.
Built with high-life ball bearings and a stainless steel shaft, it withstands significant radial and axial loads up to 50G under transient conditions. Reliable operation between -30°C and +85°C. Technical consultation and specialized distribution available in [location missing]. guemisa.es.
- Configurable resolution from 2 to 13 bits with Gray, Binary or BCD codes.
- Anodized aluminum metal housing with servo-mount flange for heavy industrial mounting.
- Vibration resistance of 50 kilocycles and guaranteed starting torque of 18 / 30 / 8 gcm.
- Up to 70mA output with PTC protection for noisy electrical environments.
Technical Frequently Asked Questions
What alignment precautions does the A/363S axle require?
The shaft is made of stainless steel and must be kept free of dirt to avoid optical errors. A radial/axial load of 5 kg and an axial load of 5 kg are recommended, ensuring that the servo-mount flange is perpendicular to the shaft to prevent premature wear of the sealed ball bearings.
What connectors and output options are available for the A/363S?
The model supports standard parallel, SSI serial, or analog (current/voltage) connections. Connectors include PT02A16-26P IP65, MS310A18-1P IP65, and DB25P IP64. The 70mA output with PTC supports resolutions from 1 to 12 bits, offering robustness against electrical noise.
What are the environmental conditions or operating limits of the A/363S?
The encoder operates between 0°C and +70°C in continuous operation, with storage permitted from -30°C to +85°C. It withstands burn-in temperatures of +75°C for 72 hours and has a ball bearing life of 1.5×10^9 revolutions under normal load conditions.
How does the A/363S integrate with control systems using analog signals?
The analog interface converts the bit resolution into current (1–20 mA) or voltage (0–10 V) proportional to the angular value. This allows direct reading by PLCs without the need for additional converters, maintaining the accuracy of Gray code or Excess-3 in specific versions under external clock control.
