*1 An upstream side pressure of 0.2 MPa or less (a filter/regulator adjustment pressure of 0.2 MPa or less for the standard model) worsens the flow rate characteristic of the shut-off valve.
*2 This value is guaranteed by KEYENCE inspection facilities while testing with air. Errors will be introduced by factors such as the gas type, gas temperature, and ambient temperature.
*3 Value in an environment with a constant temperature of 25°C 77°F and compressed air evaluated as purity class 1*1 (ISO 8573-1 (2010)/JIS B 8392-1 (2012)).±(5.5% of RD + 0.5% of F.S.) when equivalent to purity class 3*4.
*4 15 ms is added to the analog output response time.
*5 Measurable when at least 2% of F.S. worth of gas is flowing.
*6 The prescribed accuracy may not be met or the unit may be damaged if the compressed air contains a large amount of oil mist, organic solvent, or other gas. (For details, see “Gas Being Measured” on page 4.)
*7 When the flow is 5% of F.S. or higher. Errors due to heat generated by the main unit occur when the flow is too small.
*8 When connecting MP-FEA1 and/or MP-FEN1, add each device’s current consumption (2.1 A or less including load current).
*9 Use an IO-Link master that can supply 1.2 A or more. (1.6 A or less when connecting an MP-FEA1 and an MP-FEN1.) IO-Link is a registered trademark or trademark of PROFIBUS Nutzerorganisation e.V. (PNO).
*10 When protection is provided to prevent dust and liquid from intruding through the exhaust port. The IP67 enclosure rating is lost when a USB connection is established.
*11 If this product is used with a power supply voltage of 26.4 V or more, the upper limit on the ambient temperature is 45°C 113°F.
*12 Nylon is only used on the MP-Fx20R.
