Small Optical Encoder Modules
360 Ipi Analog Current Output
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.
The HEDS-971x provides sophisticated motion
detection, making closed loop control, very cost
competitive. Typical applications include printers,
plotters, copiers and office automation equipment.
