HEDS-970x, HEDS-972x Series
Digital Output Small Optical Encoder Modules
Data Sheet
Description
The HEDS-9700 series is a high performance, low cost,
optical incremental encoder module. When operated
in conjunction with either a codewheel or codestrip,
this module detects rotary or linear position. The
module consists of a lensed LED source and a detector
IC enclosed in a small C-shaped plastic pack age. Due
to a highly collimated light source and a unique photo-
detector array, the module is extremely tolerant to
mounting misalignment.
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 an 11
mm 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 ...
