The AEDT-981x module series features a built-in interpolator supporting a wide encoding resolution range from 1,000 to 5,000CPR using a codewheel of 11mm optical radius with a gap range of ±0.15mm. Compared to competitive solutions on the market, the AEDT-981x is 70% lower in supply current minimising encoder power consumption and has a wide spatial play tolerance and codewheel gap, providing ease of motor shaft alignment and enhancing photo detector signal integrity.
Measuring 26.67×20.8×10.16mm, the encoders feature typical current consumption of 20mA, spatial play tolerance of 0.4mm and operating temperature range from -40 to +115°C.
Hassan Hussain, Vice President and General Manager, Motion Control Product Division, Avago, comments: “With recent advances in automation, robotics and control systems, we have witnessed a dramatic increase in the number of new applications that need higher encoding resolution and lower power consumption. Even customers of our legacy HEDS-914x products have demanded a more robust, higher performance motion encoder solution to fulfil their new application requirements. The AEDT-981x is not only an integrated response to the new requirements of our customers, but also this series of encoders has been provisioned to support next-gen high precision motion control applications.”
The encoder is available in a standalone module unit like the AEDT-981x or in three pre-assembled housed module kits. The AEDM-5xxx is a kit with patented snap on cover, the AEDC-5xxx is a kit with connector latch and the AEDL-5xxx is a kit with integrated differential line driver IC supporting RS-422 outputs. Samples and production quantities are available now.
