X, Y, Z, W photo sensor
(a) The X1, X2, Y1, Y2, Z1, Z2, W1, W2 are connected to PIR collector pins respectively. In order to
reduce the pin count, X/Z axis and Y/W axis are shared with the same input pins. X,Y axis’s IR
LED is controlled by XYEN pin and Z,W axis’s IR LED is controlled by ZWEN pin. Each IR
control pin is turned on periodically from 20us/per 208us (Full Speed) , 20us/per 1040us (standby
mode) and 20us/per 10ms (Sleep mode) for power saving.
(b) The photo sensor pin threshold voltage is around 0.8 Volt. It is necessary to adjust the current limit
resistor and photo sensor’s emitter resistors for different photo sensor and roller wheel mechanical
parts.
