ROTARY ENCODER OPTICAL (AS38-H39E-B13S)

This AS38 absolute encoder is available with a high-resolution option of 39-bits (16-bits multi -turn and 23-bits single-turn). Structure wise, the single-turn absolute encoder contains the detector Opto-ASIC that is accompanied by a high-precision amplifier circuitry and coupled with a special multi-track code disk that rotates between the emitter and the detector. On the multi-turn side, the power is harvested using the energy-harvesting technology. When the shaft is rotating, the magnet mounted on the shaft moves in tandem. The energy-harvesting coil module cuts the moving magnet field, and generates energy as a result. The beauty of the energy-harvesting effect is that the same amount of energy is generated independent of the rotation speed. The generated energy is sufficient to power the revolution tracking circuitry. Therefore, no miss counts occur even in the absence of an external power supply.
