*1 Colour type only.
*2 Monochrome type only.
*3 Tools can be installed by programs. This is the number of detection tools and position adjustment tools. Up to 64 detection tools can be set. The number of detection tools in Sorting mode are eight tools.
*4 Saves to the sensor amplifier’s internal memory. The images saved to the sensor amplifier can be backed up to a USB memory stick inserted into the control panel (IV3-CP50) or to the PC where the software for the IV3 Series (IV3-H1) is being used.
*5 Learning tool only.
*6 Can also be displayed on the control panel (IV3-CP50) or the software for the IV3 Series (IV3-H1).
*7 Usable on the software for the IV3 Series (IV3-H1).
*8 Make sure to keep a total of each output with 160 mA or less.
*9 Conformance Class B, Applicable protocol: LLDP, SNMP.
*10 When a communication unit (DL Series) is connected.
*11 Use only products recommended by KEYENCE.
*12 For situations where the operating ambient temperature will exceed 40°C, follow KEYENCE’s specified heat dissipation measures to ensure the case temperature does not exceed the rated maximum temperature (65°C). Check the instruction manual for more information.
