... This index output electrical degree high true index pulse. The HEDT-9040 is designed for codewheels which have an optical radius of 23.36 mm (0.920 in.). The HEDT-9140 is designed for codewheels which have an optical radius of 11.00 mm (0.433 in.). The quadrature signals and the index pulse are accessed through fi ...

... Theory of Operation The HEDT-9040 and 9104 are emitter/detector modules. Coupled with a codewheel, these modules translate the rotary motion of a shaft into a threechannel 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 ...

... The HEDS-8905 alignment tool is recommended for mounting the HEDT-9140 module with Side B as the mounting plane. This tool can only be used when the HEDT- 9140 module is mounted with the HEDS-5140 (codewheel with hub). The HEDS-8905 tool fi xes the module position using the codewheel hub as a reference ...

... Mounting with Aligning Pins The HEDT-9040 and HEDT-9140 can also be mounted using aligning pins on the mounting surface. (Avago does not provide aligning pins.) For this confi guration, Side A must be used as the mounting plane. The aligning recess centers must be located within the 0.13 mm (0.005 in.) Radius Tolerance Circle as explained in “Mounting Considerations. ” ...

... Index pulses may be placed arbitrarily over a full codewheel rotation. This is done by altering only the pattern of the codewheel with no modifi cations necessary to the HEDT-9X40 module. The only restriction is that, depending on the CPR of the codewheel, consecutive index pulses may have to be separated by at least 10 full cycles ...
