Note:
1. As measured between sensor and microprocessor.
2. The values are measured with a white paper having a 90% reflection factor.
3. Defined as the variation of sensitivity between products. The variation is the change of the calculated analog output by distance
(slope of the straight output line.) Refer to “Microprocessor Divided Output vs. Distance” graph in Engineering Data.
4. The resolution means the electrical noise width on the calculated analog output converted into distance when using a 10-bit or more
A/D converter.

Technical Information
This product, developed for use in electronic equipment, is an optical displacement sensor that uses a position-sensitive detector (PSD).
The following features are characteristic of the optical displacement sensor when directly connected to a microprocessor provided by the user.
1. The color or the reflection factor of a sensing object has little effect on the analog output.
2. The inclined face of a sensing object has little effect on the analog output.
3. Linear compensation is not required
