Data Sheet
Description
The HEDS-971x is a high performance incremental
encoder module. When operated in conjunction with
either a codewheel or codestrip, this module detects
rotary or linear position. The encoder consists of a lensed
LED source and a detector IC enclosed in a small C-shaped
plastic package. Due to a highly collimated light source
and a unique photodetector array, the module is extremely
tolerant to mounting misalignment.
The two channel analog outputs and 5 V supply input are
accessed through four solder plated leads located on 2.54
mm (0.1 inch) centers.
The standard HEDS-971x is designed for use with an
appropriate optical radius codewheel or linear codestrip.
Other options are available. Please contact the factory for
more information.
Applications
The HEDS-971x provides sophisticated motion detection,
making closed loop control, very cost competitive. Typical
applications include printers, plotters, copiers and office
automation equipment.
