    Pressure and Vacuum Switches

    Image of Product. Front orientation. Pressure and Vacuum Switches. Pressure and Vacuum Switches.
    Because these switches work with both positive and negative (vacuum) pressures, you can use them in applications that span both. For example, these switches can turn on a light when they reach the setpoint to indicate which pressure is flowing. They’re also often used to trigger automated controls and activate alarms. These switches are single pole, double throw (SPDT) and can either turn one circuit from off to on or from on to off.
    NEMA 4X and IP66 rated, they’re dust tight and protected from washdowns and corrosion. All are UL and C-UL listed, CSA and CSA-US certified, and CE marked, so they meet U.S., Canadian, and European safety standards.

    Electronic Pressure and Vacuum Switches for Compressed Air

    Image of Product. Front orientation. Pressure and Vacuum Switches. Electronic Pressure and Vacuum Switches for Compressed Air.
    Designed specifically for air systems, these switches send signals to your programmable logic controller (PLC) to activate controls or alarms when your system reaches a set pressure or vacuum. All meet at least one American, Canadian, or European safety standard.
    Monitor pressure, setpoint, and reset point on the digital display. Use the display’s buttons to change your settings. These switches have an adjustable reset point (also called adjustable deadband or differential), so you can control the amount of pressure or vacuum change before the switch resets. Choose anywhere within the setpoint range for your reset point.
    1 Configurable Output—Switches with 1 configurable output give you flexibility to choose between PNP, NPN, or IO-Link. When using IO-Link, you can remotely control and monitor your vacuum from your PLC or PC when you connect an IO-Link controller (not included).
    IP65 Enclosure Rating—IP65 rated switches protect from dust and light rinsing.

    Dual-Setpoint Electronic Pressure and Vacuum Switches for Compressed Air

    Image of Product. Front orientation. Pressure and Vacuum Switches. Dual-Setpoint Electronic Pressure and Vacuum Switches for Compressed Air.
    With two setpoints, these switches trigger different actions in your air system by sending signals to a programmable logic controller (PLC) when they reach one of their set pressures or vacuums. For example, they can activate one light when a system is pressurized and another when it’s under vacuum. They have an adjustable reset, so you can control the amount of pressure change before the switch resets. This pressure difference is also called deadband or differential. Choose a reset point anywhere within the setpoint range.
    Easily monitor your pressure or vacuum setpoint on the digital display. Use its buttons to adjust the settings and setpoint.
    These switches are rated IP65 to seal out dust and water from light rinses. They’re CE marked, UL and C-UL recognized components, and CSA certified to meet American, Canadian, and European safety standards.
