^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 due 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 The FR-S01 and FR-LM20L/LP20L can be used up to an ambient temperature setpoint of 10°C 50°F by selecting “Off when not in Operation” under “Screen Brightness.” ^6 When performing SIP with FR-S01/FR-LM20L/LP20L/LS20L, be sure to turn off the power and perform at an ambient temperature of 40°C 104°F or less and an internal temperature of 130°C 266°F or less for up to one hour. In addition, always install the KEYENCE optional ferrule mounting bracket and internal gasket.
