Single-turn Absolute Encoder A/363QJ
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
The A/363QJ Single-Turn Absolute Encoder addresses the critical need in industrial automation to keep costs low without sacrificing system reliability. Designed for budget-conscious environments, it offers a robust solution that eliminates the complexities of unnecessary multi-turn encoders.
The unit provides a maximum resolution of 10 bits (1024 positions) with flexible power supply between 5V and 30V. Its architecture allows Up/Down switching and electronic output configured for parallel, SSI, or analog interfaces, adapting to existing control logic without requiring system changes.
Constructed with a composite body and sealed bearings, it withstands vibrations up to 12G and operating temperatures from -30°C to +85°C. Its Ø9.52mm stainless steel shaft ensures mechanical precision in demanding environments. Full technical information is available upon request. guemisa.es.
- Maximum resolution of 1024 positions with Gray or Excess code.
- Bearing life of 1.5×10^9 turns under continuous partial load.
- IP65 protection on both the outlet side and the tree side.
- 18/30 gcm starting torque compatible with frequencies up to 2000 Hz.
Technical Frequently Asked Questions
How does the standard parallel interface differ from SSI or analog options?
The parallel (-) interface is the standard for direct bit reading, while (S) Serial SSI offers robust serial transmission. Options (A) and (V) convert the angular position into proportional analog current or voltage, useful for PID controllers without the need for additional digital conversion.
What alignment precautions does the A/363QJ shaft require during installation?
The Ø9.52mm stainless steel shaft supports radial and axial loads of up to 50G. It is crucial to ensure there is no excessive mechanical misalignment to prevent premature wear of the sealed bearings, especially when operating near the maximum continuous RPM limit.
What connectors and wiring options are available for the electrical connection?
One meter of cabling with IP65 protection is offered. Options include 26-pin (PT02A16-26P), 10-pin (MS310A18-1P) or DB25P connectors for specific interfaces, all designed to withstand industrial conditions and facilitate integration with existing control systems.
What are the permitted operating temperature and storage limits?
Operation is guaranteed between 0°C and +60°C, while storage supports a wider range of -30°C to +85°C. The product includes a temperature rise test at +75°C for 72 hours to ensure the stability of the LED and phototransistor optical sensors.
How does the A/363QJ integrate with control systems that require analog signals?
For analog applications, the standard version converts the 10 bits into a 4–20 mA current or a 0–10 V voltage. This allows direct integration with PLCs or controllers that read analog inputs, eliminating the need for additional external A/D converters in the system.
