SMC ZSE20F-N-P-C6L-B Digital Pressure Switch for Vacuum and Compound Pressure

The SMC ZSE20F-N-P-C6L-B is a high-precision digital pressure switch from the ZSE20 series, designed specifically for accurate vacuum and compound pressure measurement and control. Featuring a 3-screen, 3-color LCD display, it offers enhanced visualization for critical parameters, facilitating easy monitoring and configuration in industrial automation and manufacturing processes.

• Advanced Display Technology: Equipped with a three-screen display presenting main and two sub-screens, each utilizing distinct colors (red/green for main, orange for subs) to clearly differentiate measurement data and settings, enhancing usability for operators in complex operational environments.
• Versatile Communication Interface: Incorporates a newly added M12 connector type within the 20B series line, ensuring robust electrical connection with standardized industrial connectors.
• Expanded Pressure Range Options: Includes a low-pressure variant in the 20A series, optimized for subtle vacuum or compound pressure applications, with a display accuracy of ±2% full scale ±1 digit and repeatability of ±0.2% full scale ±1 digit at standard ambient temperature (25 ±3°C).
• IO-Link Compatibility: An IO-Link compatible version is available in the 20C series, enabling seamless integration into Industry 4.0 infrastructures for real-time data exchange and device diagnostics with control systems.
• Rapid Response and Low Power Consumption: Features a switch output delay time of 1.5 milliseconds or less, permitting near-instantaneous switching response, combined with extremely low current consumption at 25 mA or less, minimizing power demand in continuous operation.
• Flexible Setting and Operation: Offers simple, intuitive 3-step parameter configuration and an easy screen switching function to adjust setpoints, hysteresis, delay time, and output modes without complex programming. Output modes include hysteresis and window comparator, with selectable output polarity (normal or reversed).
• Robust Electrical and Mechanical Specs: Compatible with power supply voltage of 12 to 24 VDC ±10% with ripple below 10%, protected against polarity reversal, and provides a maximum load current of 80 mA with internal voltage drop kept at 1 V or less during operation.
• Durability and Application Range: Designed to withstand pressures up to 500 kPa (low pressure models) and 1.5 MPa (high pressure models), suitable for general fluids, air, non-corrosive and non-flammable gases in industrial automation, semiconductor manufacturing, vacuum systems, and process control.

This digital pressure switch supports multiple pressure unit displays, including MPa, kPa, psi, bar, mmHg, and inHg, facilitating versatile deployment across international standards and application protocols. Its compact design offers flexible mounting options including bracket and panel installations.
