*1 If using at 3 m or more, it is recommended that the polarizing filter be removed before use.
*2 Color type only.
*3 Monochrome type only.
*4 Can be placed on a program-specific basis. This is the total combined number of differentiation tools and position adjustment tools. Up to 64 differentiation tools can be placed. Up to 16 AI Count/AI OCR tools can be placed. In Sorting Mode, 8 differentiation tools can be placed. In AI Through Count Mode and High Speed/Standard Mode, the number of tools that can be placed is two AI Count tools and one Total tool. For high accuracy, six AI Count tools and two Total tools can be placed.
*5 Saved to the sensor’s internal memory. Images saved to the sensor’s internal memory can be backed up to a PC using the PC software (IV-H1SN) or to a USB memory stick or microSD card plugged into the control panel (IV4-CP70) or Display Expansion Unit (IV4-DU10).
*6 AI Differentiate only.
*7 Focus position can be automatically adjusted during installation. It cannot be adjusted while running. Focus position can be registered separately for each program.
*8 Maximum exposure time is 500 ms only when lighting is set to OFF.

*10 Can be used with PC software (IV-H1SN).
*11 Set total output to 120 mA or less. Residual voltage specifications apply to an output current of 20 mA or less. For an output current of 50 mA, the value is 2.0 V.
*12 For PoE-powered devices, IEEE802.3at Power Class 4 or higher is recommended when using AI imaging illumination units; IEEE802.3bt Power Class 6 or higher is recommended when an AI imaging illumination unit is not in use. When using PoE, device operation may be restricted due to power limitations.

*14 Use KEYENCE-recommended products.
*15 24 VDC +25%/−10% (including ripple) when using OP-88656 (10 m 32.8').
*16 The system is designed to lower its peak current when equipped with an AI imaging illumination unit. Without it, the peak current will be higher.
*17 Except when polarizing filters (OP-88640/OP-88641/OP-88644/OP-88645) are installed.
*18 When the operating ambient temperature exceeds 40°C, install in accordance with KEYENCE instructions, taking appropriate measures for heat dissipation to ensure that the case temperature does not exceed the rated 75°C. Refer to the instruction manual for more information.
