Response speed selection function

Set DIP switch 3 to select whether to output every measured value or

the average of 8 measured values (moving average).

LOW:

Outputs the value of the average of 8 measured values. Offers more

stable detection when the luster of the target varies greatly.

HIGH:

Outputs every measured value. Offers high-speed response when the

target vibrates or moves quickly.

USING EACH FUNCTION DIP SWITCHES

Sampling cycle 128 µs 256 µs 512 µs 2048 µs

LOW Approx. 1 ms Approx. 2.0 ms Approx. 4.0 ms Approx. 17 ms

HIGH Approx. 0.1 ms Approx. 0.2 ms Approx. 0.5 ms Approx. 2 ms

Example: To cancel the influence by surface roughness, LOW is

recommended.

Example: To detect abrupt changes such as height differences,

HIGH is recommended.
