AS38-H39E-B13S 39 Bits Multi-Turn Absolute House Encoder with BiSS-C Mode Output Data Sheet Description Features This AS38 absolute encoder is available with a high-resolution 39-bits resolution: 16-bits energy-harvesting multi-turn option of 39-bits (16-bits multi -turn and 23-bits single-turn). and 23-bits optical single-turn Structure wise, the single-turn absolute encoder contains the With CRC and alarm status bits detector Opto-ASIC that is accompanied by a high-precision Built in with BiSS-C mode communication protocol amplifier circuitry and coupled with a special multi-track code Overall encoder outer diameter 38 mm, and maximum disk that rotates between the emitter and the detector. height of 40 mm On the multi-turn side, the power is harvested using the Supporting 8-mm diameter of the blind hollow shaft energy-harvesting technology. When the shaft is rotating, the magnet mounted on the shaft moves in tandem. The Benefits energy-harvesting coil module cuts the moving magnet field, and generates energy as a result. The beauty of the No battery or capacitor is required for position detection energy-harvesting effect is that the same amount of energy is during power failure generated independent of the rotation speed. The generated Immediate position detection on power up energy is sufficient to power the revolution tracking circuitry. Therefore, no miss counts occur even in the absence of an external power supply. Applications Robot and robotic engineering Factory automation Angular and linear positioning system CNC machine tool NOTE Avago encoders are not recommended for use in safety-critical applications for example, ABS braking systems, power steering, life support systems, and critical care medical equipment.
