Technical Overview

Electronic pressure switch for dry compressed air (-1 to 10 bar). Features 1/4" NPT port, PNP/NPN/analog outputs, dual-color LCD, and IP65/IP67 rating.

Key Features

  • Measuring range of -1 bar to 10 bar with 15 bar overpressure safety
  • Built-in dual-color LCD (green/red) for quick visual status of switching points
  • Versatile outputs: PNP/NPN/Push-Pull and analog (4-20 mA / 0-10 V)
  • 1/4-inch NPT female process connection (compatible with bottom or rear configurations)
  • Durable polycarbonate housing with IP65 and IP67 enclosure ratings
  • M12, 4-pin round connector for rapid and secure electrical integration

High-visibility, dual-color LCD instantly indicates system pressure states alongside versatile PNP/NPN/Push-Pull and analog outputs.

Industrial Applications

1. Pneumatic Line Pressure Monitoring

Utilizes the -1 to 10 bar measurement range and dual-color LCD to ensure automated manufacturing lines maintain optimal compressed air levels.

Problem Solved

Prevents system under-pressurization, which can lead to incomplete actuator strokes or clamping failures in critical pneumatic equipment.

2. Vacuum Grip and Lift Systems

Leverages the negative pressure measurement capabilities down to -1 bar to verify the presence of a sufficient vacuum before initiating robotic lifting sequences.

Problem Solved

Eliminates the risk of dropping heavy or delicate workpieces by supplying instant digital output confirmation of vacuum strength to the system PLC.

3. Compressor Output Regulation

Integrates the continuous 4-20 mA analog signal into variable frequency drive (VFD) controls to modulate compressor speed based on real-time plant air demand.

Problem Solved

Optimizes plant energy consumption by continuously matching compressor output precisely to the actual air requirement instead of operating on inefficient basic on/off thresholds.
