Data Sheet AEDT-981x High Temperature 115C, High Resolution, Three Channels Optical Incremental Encoder Modules Description Features The Broadcom AEDT-981x encoders are industrial grade 40C to 115C operating temperature high temperature (40C to 115C) rating three channel Two-channel quadrature output with index pulse optical incremental encoder modules building on the Single-ended output with 5 mA output sink/source Broadcom legacy HEDS-9140 series. current per channel Suitable for industrial applications Using a Broadcom-developed opto ASIC with the built-in Resolution up to 5000 counts per revolution Interpolator circuit, AEDT-981x encoders enable wide Low power consumption (typical Icc: 20 mA) resolution range from 1000 to 5000 counts per revolution No signal adjustment required with the rotary codewheel of 11-mm optical radius, offering Pin compatible to legacy HEDS-9xxx series a high resolution yet compact solution. Spatial play tolerance of 0.40 mm With the opto-ASICs built-in automatic LED brightness Allows motor shaft axial play of 0.15 mm regulation technique, the encoder current consumption can ESD Immunity HBM 4kV (JESD22-A114D) be significantly lowered (Typ. Icc: 20 mA) while maintaining optimal encoder performance across spatial corners. This Applications LED brightness control feature also enables optimal LED current control hence, LED life can significantly prolonged. The AEDT-981x series provide high temperature motion control detection with ease of installation, making them With the state-of-the-art opto-mechanical design, suitable for wide range of commercial and industrial AEDT-981x offers excellent spatial play of 0.40 mm and applications. code wheel gap range of 150 m. This allows great flexibility and ease of installation to the user. NOTE: Broadcom encoders are not recommended for use in safety critical applications for example, ABS Inheriting the indefeasible integrity in product robustness, braking systems, power steering, life support repeatability and reliability, AEDT-981x series are designed systems, and critical care medical equipment. for wide market employment withstanding wide application Please contact sales representative if more requirement and environment demand. clarification is needed. CAUTION It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation that may be induced by ESD.
