Notes:
6. Measured from a reflector coated with 99% diffuse reflective white paint (Kodak 6080) positioned 4.27 mm (0.168 in.) from the
reference plane. Measured physically is the total photocurrent, Ipt, which consists of a signal (reflected from target) component,
Ipr, and a component induced by reflections internal to the sensor (stray), Ips. Ipt = Ipr + Ips. Specified is the reflected signal
component, Ipr.
7. See Bin Table
8. <Q> = Ipr/Ipt
9. Measured from reference plane (R.P.) of sensor.
10. Photocurrent variation with temperature varies with LED output which follows a natural exponential law:
Ip(T) = Ip(To)*exp[Ke(T-To)]
11. OSR is defined as the distance for a 10%-90% “step” response of Ipr as the sensor moves over an abrupt black-white edge, or from
opaque white to free space (no reflection).
