Color Discrimination Mode Selection (Mode C is Recommended for Normal Applications)
Mode C: Color discrimination is performed according to R (red), G (green), and B (blue) ratio of the reflection light even
if the sensing objects fluctuate up and down within the rated sensing range.
Mode I: Color discrimination is performed according to RGB light intensity of reflection light. This mode ensures more
delicate color discrimination than mode C.
Response Time Selection
3 ms (6 ms): The E3MC can stably detect minute differences of color. Set the response time to 3 ms for usual
1 ms (2 ms): The E3MC will be in quick-response operation. Set the response time to 1 ms if high-speed response is
OFF-delay Timer Setting
---: No OFF-delay timer is set.
TMR: A 40-ms OFF-delay timer is set for control output.
