ISE40A-01-T-X501 SMC High Precision 2 Color Digital Pressure Switch Positive Pressure

The SMC ISE40A-01-T-X501 is a state-of-the-art digital pressure switch from SMC's renowned ISE40A series, specifically engineered for positive pressure monitoring of air and non-corrosive gases. This advanced unit represents the evolution of pressure sensing technology, combining high-precision measurement with a user-friendly 2-color LED display and sophisticated connectivity options.

Unlike traditional analog gauges, this switch delivers digital accuracy (±2% F.S.) and exceptional repeatability (±0.2% F.S.), making it ideal for sophisticated automation systems requiring precise pressure control and reliable data feedback. The "X501" suffix indicates a 3-meter lead wire configuration, providing enhanced flexibility for installation in large control cabinets or remote locations.

• Dual-Color LED Display: Bright, easy-to-read 2-color (Red/Green) digital display with instant color changes to indicate operational status
• High-Precision Sensing: Utilizes high-sensitivity sensor with stainless steel diaphragm for stable, accurate readings in fluctuating environments
• Smart Copy Function: Transfer settings from one master unit to up to 10 slave units simultaneously via communication port
• Hybrid Output Capability: Standard NPN/PNP open collector outputs plus analog voltage output (0.6-5V) for real-time monitoring
• Robust Environmental Protection: IP65 rating (NEMA 4 equivalent) for protection against dust and water jets
• User-Friendly Operation: Simple 3-step setting process with password protection for parameter security
• Energy Saving: Power-saving mode reduces energy consumption by up to 20% compared to previous models

Understanding the SMC coding system helps in selecting the exact variant:

• ISE40A: Series designation for Positive Pressure, High Precision
• 01: Port size specification (R 1/8 thread)
• T: Output specification (NPN Open Collector x2 + Analog Voltage/Switch selectable)
• X501: Custom specification code indicating a 3-meter lead wire (Standard is 2m; X531 indicates M12 connector)

• PLC Connection: NPN open collector outputs wire directly to PLC input cards for alarms; 0-5V analog output connects to analog input modules for real-time monitoring
• Vacuum Systems: Wide range (-0.1 MPa) allows monitoring of rough vacuum levels down to -100 kPa gauge
• Mounting: Surface-mounted using rear brackets or panel-mounted for control cabinet integration
