HEDS-8907-001

The HEDS-8904 comes in an option of two-channel or three-channel optical incremental encoder kit with codewheel integrated in a protective housing. The encoder is lead free and compliant to the RoHS directive. Each encoder kit consists of a collimated LED source and a detector IC enclosed within a small plastic package. The HEDS-8904 optical encoder has two-channel quadrature outputs (A,B) plus a third channel index output (I). There are three index options available. i.e. ungated, gated-90° and gated-180 ° electrical degree index pulse. The HEDS-8904 series optical encoder is designed for use with motors with shaft diameters of 2mm and up to 5mm. The quadrature, index and power supplied to the encoder are accessed through an 8-pin male connector of 1.25 mm pitch. The HEDS-8904 solution enables the servo system to be more compact. With the aid of alignment jig, the assembly process will also require less alignment time, thus making the assembly process much easier for servo motor integration.
