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.
