PHOTO IC
Photo IC for laser beam synchronous detection
Photo IC for start timing detection for precise printing
S5049 series
S5049 uses a dual-element PIN photodiode and compares the two photocurrent signals to maintain a highly stable output even when input laser
power or ambient temperature fluctuates. Two types of sensors are available to meet different operating conditions.
