Air Pressure Switch ISE20B-L-01-WD
The SMC ISE20B-L-01-WD is a high-precision digital air pressure switch designed for monitoring and control of compressed air systems in industrial automation applications. The device features a highly visible 3-screen, 3-color display that simultaneously shows measured pressure values and switch settings, allowing operators to quickly assess system status.
The sensor supports IO-Link communication, enabling remote parameterization, diagnostics, and process monitoring from PLC and automation systems. In addition to IO-Link operation, the unit can function as a standard digital pressure switch with a selectable PNP/NPN switching output. Its compact design, fast response time, IP65 protection, and easy setup make it suitable for pneumatic machinery, automation equipment, packaging systems, and factory process control applications.
The SMC ISE20B-L-01-WD is a compact, high-precision digital air pressure switch with IO-Link communication, R1/8 process connection, IP65 protection, 3-screen color display, and selectable PNP/NPN switching output, designed for industrial pneumatic monitoring and automation systems.
