^1 Guaranteed value in water with the recommended installation. Static water can be measured up to the edge of the lens. An undetectable area on the short-range side is created owing to the environment and measurement medium. The maximum measuring distance is also shortened. ^2 Measurement may not be possible depending on the shape and environment of the target. ^3 This is the guaranteed value from verification performed at KEYENCE inspection facilities. Measurement errors may occur depending on the customer’s environment. ^4 This is the guaranteed value from verification performed at KEYENCE inspection facilities with a load resistance of 250 Ω. Measurement errors may occur depending on the customer’s environment. ^5 Details of the operating temperature range of each model are shown below. The FR-S01 and FR-LM20/LP20 can be used up to an ambient temperature setpoint of 10°C by selecting “Off when not in Operation” under “Screen Brightness.” ^6 When performing SIP with FR-S01/FR-LM20/LP20/LS20, be sure to turn off the power and perform at an ambient temperature of 40°C or less and an internal temperature of 130°C or less for up to one hour. In addition, always install the KEYENCE optional ferrule mounting bracket and internal gasket.

^1 This is the guaranteed value from verification performed at KEYENCE inspection facilities with a load resistance of 250 Ω. Measurement errors may occur depending on the customer’s environment. ^2 The number of expansion units can be increased by making the output current less than 750 mA in total. Contact your local KEYENCE representative for more details. ^3 Contact your local KEYENCE representative when adding more than the aforementioned number of units. When FR-S01 is connected: 6 units. When FR-SH01 is connected: 8 units. ^4 When expanding the FR-SA2 with the number of units indicated on the right or more, use a power voltage of 21.6 V or higher. When FR-S01 is connected: 1 unit; when FR-SH01 is connected: 8 units. ^5 When expanding the system by four or more FR-SA0 units with the FR-S01 connected or by ten or more FR-SA0 units with the FR-SH01 connected, use a power voltage of 21.6 V or higher. ^6 If the number of expansion units is one, the ambient temperature must be 50°C or less, and if the number of expansion units is two or more, the ambient temperature must be 45°C or less. ^*7 Contact your local KEYENCE representative when adding more than the aforementioned number of units.
