*1 At installation distance 50 mm, air flow 60 Nl/min (ambient temperature 20 to 30 °C, relative humidity 40 to 60 %)
*2 At installation distance 50 mm, air flow 20 Nl/min (ambient temperature 20 to 30 °C, relative humidity 40 to 60 %)
*3 Contact KEYENCE for information about derating for humidity and pressure when the ambient temperature above 35 °C. Use clean, dry air with a dew point of -20 °C or less for the supplied fluid. Also, the minimum air flow amount varies according to the nozzle. Contact KEYENCE for information about each nozzle.
*4 Use a supplied fluid with a temperature of 40 °C or less.
*5 Only for the pressure cable. Other parts should be used with an ambient temperature of 0 to 40 °C.
*6 Values obtained at an installation distance of 50 mm and air flow rate of 60 Nl/min [ambient operating temperature +20 to +30 °C, ambient operating humidity 40 to 60 % RH] (without nozzle)
*7 Values obtained at an installation distance of 50 mm and air flow rate of 20 Nl/min [ambient operating temperature +20 to +30 °C, ambient operating humidity 40 to 60 % RH] (without nozzle)
*8 Inquire for derating of humidity/pressure in environments exceeding +35 °C. Use clean or dry air at a temperature of -20 °C or less. Min. air pressure varies by nozzle used.
