E3X-DA-S

High functionality digital fiber amplifier

• High functionality digital fiber amplifier with advanced timing, LED power control and signal processing functionality providing highest detection accuracy and stability even for the most challenging objects and settings.

• Power tuning function to adjust the received light to a maximum, minimum or pre-defined value

• Auto power and threshold adjustment functions for highest operational stability

• Two outputs for window monitoring or two level detections (e.g. object + object state change)

*1.

The reverse polarity protection for the pre-wired and fiber amplifier connector models is for the power supply and the output. For M8 connector models the reverse polarity protection is for the power supply.

*2.

The communication function and mutual interference prevention function are disabled if detection is set to Super-high-speed Mode.

*3.

For fiber amplifiers with these functions and connecting with M8 connector, order the fiber amplifier connector models above and the pigtail connector E3X-CN21-M3J-2 with 30 cm PVC cable and M8 plug.

*4.

When the ECO Mode is enabled, the rated sensing distance is approx. 1/2 and the incident level is approx. 1/3 of the normal levels.
