*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.
