(vs RPM871-H12)
 
 
In case of using R1 with different condition from the above, formula is as follows :
LED resistance value : R1[&], LED average consumption current : ILED[mA], Supply voltage : VLEDVCC[V],
necessary d[cm] (Including LEDs distribution within ?5deg)
 
R1=T ?(VLEDVCC4.45) / d

ILED=Duty ?(VLEDVCC1.36) / (R1+2.5) [A]
 
Duty : LED duty at emitting
T : 17300 (vs. RPM871-H12), 29400 (vs. ver1.0)
 
 Please set up to be ILED / Duty < 200[mA] (Duty < 20%)
