This module is designed to detect rotary position when used with a code wheel. The new module consists of a lensed LED source and a monolithic detector IC enclosed in a small polymer package. The new module uses phased array detector technology to provide superior performance and greater tolerances over traditional aperture mask type encoders. The new module provides digital A & B quadrature outputs with an optional third output index channel. Each module is resolution specific and is matched to the resolution of a code wheel. All standard resolutions offered by the HEDS-9000 series encoder module, as well as additional resolutions, are now supported by the new module. The new module operates with a single 5V supply and provides single ended outputs which are capable of both sinking and sourcing 8mA at TTL levels. An internal 0.1 uF decoupling capacitor is designed into the new module to provide enhanced noise immunity over the HEDS-9000 series encoder modules. Physically , the new module has no external wire loops which can interfere when mounting. The connector pins are 0.051” shorter than HEDS modules, while still providing .30” insertion depth. When these Single-Ended Encoders with Index are attached to the end of an Anaheim Automation dual shaft motor, provide digital quadrature output. The squarewave output provide digital feedback for applications that require position and/or speed control. DIMENSIONS AND PINOUTS L010390 To order an single-ended encoder with index, add a “ - ”, the CPR n\ umber, and an SI on the end of any Anaheim Automation dual shaft motor. 23Y106D-LW8-1000SI The part number for a 1000 CPR encoder mounted on a 23Y106D-LW8 stepper motor would be 23Y106D-LW8-1000SI.
