Dynamic Sampling Rate

When using Dynamic TEACH to sample an application for programming, it is important

to consider the speed of the object being sensed. The sensor’s sampling rate during this

set-up process is much slower than its response time in RUN mode. Once sampling is

complete and the sensor returns to RUN mode, sensor response time returns to its

original value.

Use the following formula to calculate the target object speed for Dynamic TEACH

sampling:

Max. speed of object =

as it passes the sensor

For example, for an object 0.125" wide: Or for an object 2 mm wide:

(0.125" - 0.04") (2 - 1 mm)

Max. object speed = = 9.4" /second Max. object speed = = 111 mm/second

0.009 seconds 0.009 seconds

*NOTE: The Dynamic Sampling Rate for high-speed models (“Y” model suffix) is

8 milliseconds (0.008 seconds)

†

NOTE: The sensor will return to RUN mode if the first TEACH condition is not registered within 90 seconds. Dynamic TEACH mode may be

cancelled by waiting 90 seconds or by cycling sensor power.
