Overview

Broadcom AS38-H39E-B13S 39-Bits Multi-Turn Encoder is a multi-turn absolute encoder series available with a high-resolution option of 39 bits (23-bit single-turn and 16-bit multi-turn). The single-turn encoder contains a detector Opto-ASIC. This detector is accompanied by a high-precision amplifier circuitry coupled with a special multi-track code disk that rotates between the emitter and the detector. The multi-turn encoder does not need a battery as its power is generated by the Wiegand-based energy harvesting technology. When the shaft rotates, the magnet mounted on the shaft moves in tandem. The energy harvesting coil module reacts with the moving magnet field, generating count pulses and energy as a result. The beauty is that the same amount of energy is generated independent of the speed of rotation. 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.
