Overview

Pressure switches detect pressure of gases or liquids. Built-in circuitry allows for the adjustment of set points and outputs. Outputs are ON-OFF solid state or read switch type outputs. Some models feature analog outputs. The pressure is detected using solid state, metal diaphragm or piston type sensors. Applications for pressure switches include areas such as positioning, leakage testing, supply pressure verification, etc. SMC vacuum switches provide a completely integrated, digital solution designed to monitor vacuum status. Vacuum sensor and switch outputs are integrated into ultra-compact, lightweight units. Easy push button calibration eliminates the need for tools. Available in either easy-to-read LCD with backlight or LED readouts which display current measured value as well as set points and output mode information. Outputs are digital NPN or PNP and analog, with simple programming and multiple application features such as failure prediction and window comparator. Vacuum switches can be integrated directly onto many vacuum generators. Popular ISE40A and ZSE40A series digital pressure/vacuum switches now come with one-touch push-to-connect tube fittings. Choose from straight or 90… angled fittings for 4 mm, 6 mm, or 1⁄4" tubing.
