<Basic Design>
RO ( distance between the disk center and half point of a slit ) ,
P ( slit pitch ) , S 1 and S 2 ( installing position of photoint-
errupter ) will be provided by the following equations.
Slit pitch : P ( slit center )
R O=
N
60
x 10.89 ( mm )
P= 2x p x RO ( mm )
N
N: number of slits
S1= RO- 1.765 (mm ), S2= S1+ 6.7 (mm )
Note ) When the number of slits is changed, values in
parenthesis are also changed according to the number.

S2= 16.385+ 6.7
= 23.085mm
s Precautions for Use
( 1) This module is designed to be operated at I F = 30mA TYP.
( 2) Fixing torque : MAX. 0.6N • m
( 3) In order to stabilize power supply line, connect a by-pass capacitor of more than 0.01 µF
between Vcc and GND near the device.
( 4) As for other general cautions, refer to the chapter “ Precautions for Use ” .
