*1 Operating distance: 50 mm 1.97", Air volume: 60 NL/min,
(Ambient temperature: 20 to 30°C 68 to 86°F, Ambient humidity: 40 to 60%RH)
*2 Operating distance: 50 mm 1.97", Air volume: 20 NL/min,
(Ambient temperature: 20 to 30°C 68 to 86°F, Ambient humidity: 40 to 60%RH)
*3 For derating of humidity and pressure during use at an ambient temperature higher than 35°C 95°F, contact KEYENCE. For air supply, use clean dry air with -20°C -4°F or lower dew point. The minimum air volume varies depending on the nozzle type. Contact KEYENCE for more information.
*4 The supplied air temperature should be 40°C 104°F or less.
*5 For high-pressure cable only. For other parts, operating ambient temperature is 0 to +40°C 32 to +104°F.
*6 At installation distance 50 mm 1.97", air flow 60 Nl/min (ambient temperature 20 to 30 °C 68 to 86 °F, relative humidity 40 to 60 %)
*7 Values obtained at an installation distance of 50 mm 1.97" and air flow rate of 20 Nl/min [ambient operating temperature +20 to +30 °C +68 to +86 °F, ambient operating humidity 40 to 60 % RH] (without nozzle)
*8 Inquire for derating of humidity/pressure in environments exceeding +35 °C 95 °F. Use clean or dry air at a temperature of -20 °C -4 °F or less. Min. air pressure varies by nozzle used.
*9 Use a supplied fluid with a temperature of 40 °C 104 °F or less.
*10 Only for the pressure cable. Other parts should be used with an ambient temperature of 0 to 40 °C 104 °F.
