The SROA79 Crossed Shaft Coupling Encoder is an absolute rotary encoder, based on the cross-slider principle, and is suitable for applications where the shaft has significant eccentricity or axial runout.
The SROA79 Crossed Shaft Coupling Encoder is resistant to vibration and impact, high temperatures, and has a high protection rating, making it ideal for use in industries such as machine tools.
Absolute positioning accuracy < ±50 arcseconds, repeatability accuracy < ±20 arcseconds;
RS485 interface, compatible with multiple communication protocols;
Bidirectional asynchronous serial communication, single-turn 17/23bit (up to 25bit), multi-turn 16bit;
Rigorous EMC testing, suitable for harsh electromagnetic environments;
Suitable for motors with a 130 flange or larger;
The peripheral structure, combined with the motor rear cover design, allows for easy replacement.
Higher precision and rigidity;
Vibration resistance, shock resistance, easy maintenance;
Effectively reduces the influence of motor heat conduction.
