Optical Incremental Encoder Module 5-Pin

AEDT-981x encoders are industrial grade high temperature (-40 to 115°C) rating three channel optical incremental encoder modules building on the legacy HEDS-9140 series. Using an developed opto ASIC with the built-in Interpolator circuit, AEDT-981x encoders enable wide resolution range from 2000 to 5000 count per revolution with the rotary codewheel of 11mm optical radius, offering a high resolution yet compact solution. With the opto-ASIC’s built-in automatic LED brightness regulation technique, the encoder current consumption can be significantly lowered (Typ. Icc: 20mA) while maintaining optimal encoder performance across spatial corners. This LED brightness control feature also enables optimal LED current control hence LED life can significantly pro-longed. With the state of the art opto-mechanical design, AEDT- 981x offers excellent spatial play of Ø 0.40mm and code wheel gap range of ±150um. This allows great flexibility and ease of installation to the user.
