... This index output electrical degree high true index pulse which is gener- ated once for each full rotation of the codewheel. The AEDB-9140 is designed for use with a codewheel which has an optical radius of 11.00 mm (0.433 inch). The quadrature signals and the index pulse are accessed through five 0 ...

... Theory of Operation The AEDB-9140 are emitter/detector modules. Coupled with a codewheel, these modules translate the rotary motion of a shaft into a three-chan- nel digital output. As seen in Figure 1, the modules contain a single Light Emitting Diode (LED) as its light source. The light is ...

... CH I fall afterCH A or -10° 85° rise Electrical Interface To insure reliable encoding performance, the AEDB-9140 three channel encoder modules require 2.7 kΩ (± 10%) pull-up resistors on output pins 2, 3, and 5 (Channels A, I and B) as shown in Figure 3. These pull-up resistors should be located as close to the encoder module as pos- sible (within 4 feet). Each of the three encoder module outputs can drive a single TTL load in this confi ...
