SMC 10-ISE20A-R-P-C4L | Clean Room 3-Screen Digital Pressure Switch ISE20A Series 2 Outputs + Analog Positive Pressure R8 Connector

The SMC 10-ISE20A-R-P-C4L is a clean room specification high-precision digital pressure switch from the ISE20A series with 3-screen display, 2 switch outputs plus analog output, for positive pressure measurement. Part number decoded: ISE20A = ISE20 series A-type (2 outputs + analog), R = R8 connector type, P = positive pressure, C4L = specific pressure range and configuration option. The ISE20A provides real-time digital pressure monitoring with programmable switch points and analog output for PLC data acquisition in clean room pneumatic systems.

What makes the ISE20A valuable in clean room automation? Traditional mechanical pressure switches provide only on/off detection at a fixed set point. The ISE20A delivers continuous pressure measurement on a 3-screen LED display (showing current value, set point 1, and set point 2 simultaneously), two independently programmable NPN/PNP switch outputs for high/low alarm or process control, and a 1-5V or 4-20mA analog output proportional to pressure. This enables real-time process monitoring, trend logging, and predictive maintenance of clean room pneumatic systems where pressure drift indicates filter clogging, regulator degradation, or supply line issues.

The R connector type provides a compact 8-pin round connector for quick electrical connection. For different connector styles, ISE20A-T (terminal block) and ISE20A-M (M12) options are available. The ISE20A-R-P-C4L-JA2 adds the JA2 option for specific display or output modifications. For general fluid applications rather than air, the ISE20C series handles water, oil, and other non-corrosive fluids. Compatible with SMC clean series regulators and air preparation equipment. Clean series (10-) Particle Grade 1. RoHS compliant.
