Photoelectric Sensors
Red light diffuse reflective energetic BOS 18E-PI-RD30-S4 with IO-Link
With Teach Channel: Dynamic Teach. Dynamic Teach-In of both setpoints
Principle
Dynamic teach-in allows you to set the switching point
without interrupting the process.
Typical application:
Sensitivity setup to a moving object to be detected within a
certain distance range. (Window Mode).
During the teach procedure, which begins with the Start
command and ends with the Stop command, the sensor
carries out measurements and determines the minimum
and maximum of the obtained values. The Teach Apply
command determines the switching points SP1 and SP2.
