HDE series is a rotary optical incremental shaft encoder designed with high precision mechanical and opto-electronic components. It is enclosed in a sealed rugged anodized aluminum housing designed to operate in the most severe environments. Infrared LED and SMD circuitry provides high noise immunity. Two independent shaft seals prevent internal contamination due to moisture and dust. Teflon sealed chrome steel with grease lube (standard) and many other bearing options provide for heavier shaft loads. Single channel, index pulse, quadrature, and other special outputs are available with standard resolutions up to 2500 PPR. Over four decades of engineering and manufacturing experience is embodied in every "HDE". FSI is committed to manufacturing quality products and providing complete customer satisfaction!
