ISE20-N-M-01: 3-Screen Display High-Precision Digital Pressure Switch – Compact Smart Node for Positive Pressure Monitoring

Product Positioning
The ISE20-N-M-01 is a 3-screen display high-precision digital pressure switch from SMC’s ISE20 series, designed for positive pressure applications (-0.1～1.0 MPa). It integrates high-precision pressure sensing, a 3-color LCD display, and NPN switch output into a compact integrated body. It allows setting while observing the measured value, providing intuitive operation. It is a core component for achieving pressure visualization, precise control, and remote monitoring in industrial automation.

Core Highlights: 3-Screen Display, NPN Output, Fixed SI Unit

• 3-Screen Clear Display, Status at a Glance
  • Features 3 independent LCD screens: The main screen is a 4-digit 7-segment digital display (switchable red/green dual color), and two sub-screens are 4-digit digital displays (orange).
  • The main screen color can automatically change based on the output status, making the operational state visually intuitive and facilitating on-site monitoring and troubleshooting.
• NPN Open Collector Output, High Compatibility
  • Output specification is NPN open collector (1 output), directly connectable to various PLC control systems for switching signal feedback.
• Fixed SI Unit (MPa/kPa Display)
  • The “M” in the model indicates fixed SI units. The pressure unit is fixed to MPa and kPa and cannot be switched to other units (e.g., psi, bar).
• R1/8 Standard Port with M5 Internal Thread
  • Piping specification is R1/8 (external thread) and includes an M5 internal thread, adapting to multiple piping methods for easy integration into existing pneumatic systems.
• Millisecond Response, Captures Pressure Transients
  • Response time as low as 1.5ms or less (with no digital filtering), allowing timely response to rapid pressure changes, ensuring system safety and control accuracy.
• High Measurement Accuracy, Good Repeatability
  • Repeatability up to ±0.2% F.S., ensuring consistency and reliability of measurement results.
  • Display accuracy ±2% F.S. (at ambient temperature 25±3℃).
• IP40 Protection, Suitable for General Industrial Environments
  • Protection rating is IP40 (dust-proof), suitable for general industrial environments where water resistance is not a primary requirement.
