... The two channel digital outputs and 5V supply input are accessed through four solder-plated leads located on 2.54 mm (0.1 inch) centers. The standard HEDS-9700 is designed for use with optical radius codewheel, or linear codestrip. Other options are available. Please contact factory for more in- formation ...

... CODE EMITTER SECTION DETECTOR SECTION WHEEL 2 Theory of Operation The HEDS-9700 is a C-shaped emitter/detector module. Coupled with a codewheel, it translates rotary motion into a two-channel digital output. Coupled with a codestrip, it translates linear motion into a digital output. As seen in the block diagram, the module contains a single Light Emitting Diode (LED) as its light source. The light is collimated into a parallel beam by means of a single lens located directly over the LED ...
