About This Product

■Reflective optical incremental encoder IC with analog output/digital output version with built-in multiplication function available depending on application/resolution

SME-08BDx is a 3-channel analog/digital output reflective optical incremental encoder IC. A/B phase can be selected from analog output and digital output depending on the version. The digital output version also has a built-in multiplier circuit (4x, 8x, 16x), allowing you to set the resolution. SME-08BDx has an LED and an OEIC (Opto-Electric Integrated Circuit) mounted in one package. The relative movement between the SME-08Bxx and the codewheel is detected by projecting the light emitted from the LED onto the codewheel and receiving the reflected light with a photodiode. Furthermore, by providing a pattern for origin detection on the code wheel, the Z phase, which is the origin signal, is output.

■Features

・Package: HCOB8, 3.95×3.4×1.0mm ・Current consumption: 27mA (typ) ・Operating temperature range: -40 to +85℃ ・LED wavelength: 850nm ・LED and OEIC implemented in one package ・Built-in LED dimming function using APC circuit ・Select the output signal based on the product version. Incremental signal 2-phase analog sine wave signal/digital signal Home signal (if the incremental signal is a digital signal output) Output width: 90°e/180°e/360°e ・Reflow mounting possible

■Application example

・OA equipment: MFP, polygon mirror control ・Industrial equipment: galvano scanners, robots, machine tools, X-Y stages, microscopes, semiconductor manufacturing equipment, measuring instruments, cash terminals, servo motors, stepping motors, actuators, encoders ・Various motor control
