1250/2500 CPR Commutation Encoder Moduleswith Codewheel
Data Sheet
Description
The AEDB-9340 optical encoder series are six-channeloptical incremental encoder modules with codewheel.The encoder is compliant to RoHS directive and hadbeen declared as a lead free product. When used withcodewheel, these modules detect rotary position. Eachmodule consists of a collimated LED source and detectorIC enclosed within a small plastic package. Due tohighly collimated light source and unique photo detec-tor array designs, these modules are extremely tolerantto mounting misalignment.
The AEDB-9340 optical encoder has integrated commu-tation output (U, V, W), two-channel quadrature outputsplus a third channel index output (A, B, I). This ungatedindex output is a positive index pulse that is generatedonce for each full rotation of the codewheel.
The AEDB-9340 series optical encoder is designed foruse with a codewheel that has an optical radius of15 mm (0.590 inch) for 1250/2500 CPR, 12.3 mm (0.484inch) for 1024/2048 CPR and 12 mm (0.472 inch) for 1000/2000 CPR.
The quadrature, index, commutation signals and powersupplied to encoder are accessed through eight0.46 mm square male connector pins located on 1.27 mm(pitch).
The AEDB-9340 optical encoder provides advancedmotion control detection with integrated commutationoutputs (U, V, and W). It is equivalent to those producedby Hall Switches, thus making it ideal for servo motorapplication. With the AEDB-9340 solution, the system willbe more compact, have reduced alignment time withusage of alignment jig, thus making assembly processmuch easier for housed encoder integration. It hassuperior switching accuracy due to much lowerhysteresis when compared to a Hall Switches. The com-mutation signals can be generated for Brushless DCmotor of different rotor pole-pairs by simply changingwith matching pole-pair codewheel.
