The HEDS-9140#A00 is a Three Channel Optical Incremental Encoder with code wheel. Low cost module detects rotary position. Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package. Due to a highly collimated light source and a unique photo detector array, these modules provide the same high performance found in the HEDS-9000/9100 two channel encoder family.
Three channel quadrature output with optional index pulse
