1 / 15 page  Description The AEDB-9340 optical encoder series are six-channel optical incremental encoder modules with codewheel. The encoder is compliant to RoHS directive and had been declared as a lead free product. When used with codewheel, these modules detect rotary position. Each module consists of a collimated LED source and detector IC enclosed within a small plastic package. Due to highly collimated light source and unique photo detec- tor array designs, these modules are extremely tolerant to mounting misalignment. The AEDB-9340 optical encoder has integrated commu- tation output (U, V, W), two-channel quadrature outputs plus a third channel index output (A, B, I). This ungated index output is a positive index pulse that is generated once for each full rotation of the codewheel. The AEDB-9340 series optical encoder is designed for use with a codewheel that has an optical radius of 15 mm (0.590 inch) for 1250/2500 CPR, 12.3 mm (0.484 inch) for 1024/2048 CPR and 12 mm (0.472 inch) for 1000/ 2000 CPR. The quadrature, index, commutation signals and power supplied to encoder are accessed through eight 0.46 mm square male connector pins located on 1.27 mm (pitch). The AEDB-9340 optical encoder provides advanced motion control detection with integrated commutation outputs (U, V, and W). It is equivalent to those produced by Hall Switches, thus making it ideal for servo motor application. With the AEDB-9340 solution,the system will be more compact, have reduced alignment time with usage of alignment jig, thus making assembly process much easier for housed encoder integration. It has superior switching accuracy due to much lower hysteresis when compared to a Hall Switches. The com- mutation signals can be generated for Brushless DC motor of different rotor pole-pairs by simply changing with matching pole-pair codewheel. Features • Two-channel quadrature output with ungated index pulse (A, B, I) • Three-channel integrated commutation output (U, V, W) • Up to 2500 Cycles Per Revolution (CPR) • Easy assembly with alignment jig • Designed to fit into circular shaped housing • Up to 150 kHz frequency response • –10 °C to 85°C operating temperature • TTL compatible • Single 5 V supply • Integrated feedback device for Brushless DC Motor AEDB-9340 Series 1250/2500 CPR Commutation Encoder Modules with Codewheel Data Sheet Applications Typical applications include industrial printers, plotters, tape drives, and industrial and factory automation equipment. Note: Avago Technologies encoders are not recommended for use in safety critical applications, e.g., ABS braking systems, power steering, life support systems and critical care medical equipment.
