*1 Color type only.
*2 Monochrome type only.
*3 The focusing position can be automatically adjusted at the time of installation. Disabled during operation. The focusing position can be registered by programs.
*4 Tools can be installed by programs. This is the number of detection tools and position adjustment tools. Up to 16 detection tools can be set. The number of detection tools in Sorting mode is one tool (learning tool).
*5 Saves to the sensor's internal memory. The images saved to the sensor 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.
*6 Learning tool only.
*7 Can also be displayed on the control panel (IV3-CP50) or the software for the IV3 Series (IV3-H1).
*8 Usable on the software for the IV3 Series (IV3-H1).
*9 Make sure to keep a total of each output with 120 mA or less.
*10 For a PoE power supply device, IEEE802.3at power class 4 or higher is recommended when using the AI Lighting unit, and IEEE802.3bt power class 6 or higher is recommended when the AI Lighting unit is not used. When using a device with less than the recommended power class, operation may be restricted due to power limitation.
*11 Use only products recommended by KEYENCE.
*12 The peak current is designed to be smaller if the AI Lighting unit is mounted. The peak current is greater if the AI Lighting unit is not mounted
*13 Except when the polarizing filter (OP-88640/OP-88641/OP-88644/OP-88645) is mounted.
*14 Except when the dome attachment (IV3-D10) is mounted.
