Light source
(wave length)
Red LED (650 nm) Red LED (625 nm)
Power supply
voltage
12 to 24 VDC ± 10%; ripple (p-p): 10% max
Protective circuits Reverse polarity protection, output short circuit protection, mutual interference prevention*1
*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.
Response time
Super-high-speed
mode*2
*2. The communication function and mutual interference prevention function are disabled if detection is set to Super-high-speed Mode.
80 µs for operation and reset max. 55 µs for operation and reset max.
Standard mode 1 ms for operation and reset
High
resolution mode
4 ms for operation and reset
Wet process
'tough mode'
16 ms for operation and reset *3
*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.
