S4506
Photo IC for photointerrupters with encoder functions
S4506 incorporates a 4-element photodiode array that provides 2-phase digital output in response to the input light status. Photointerrupters with
encoder functions can be easily configured by using S4506.

l Integrated with 4-element photodiode (pitch: 0.39 mm)
l Direct TTL connection
l Miniature plastic package
Applications
l Encoders for office machine, robots, and NC machines

*2: Ev is illuminance emitted from a CIE standard “A” light source (tungsten lamp).
*3: A collimated light source and a recommended slit moving at a constant speed are used.
[Delay time between the instant that the slit passes through the output transition position and the actual output transition
should be less than 1/8 of the slit cycle.]
*4: See next page.
*5: Minimum illuminance from an “A” light source when the duty ratio of phases A and B is between 35 and 65 %.
