    Electronic Pressure Switches for Compressed Air

    Image of Product. Front orientation. Pressure Switches. Electronic Pressure Switches for Compressed Air.
    With a set pressure range that works for most air systems, these switches send signals when your air system reaches a set pressure to your programmable logic controller (PLC) to activate automated controls and alarms. All meet at least one American, Canadian, or European safety standard.
    Monitor your pressure on the display and change your setpoint, reset point, scaling, and other settings using the buttons. An adjustable reset point means you can control the amount of pressure change before the switch resets, also known as deadband or differential. Choose anywhere within the setpoint range for your reset point.
    1 Configurable Output—Switches with a configurable output give you the flexibility to choose between PNP, NPN, or IO Link. IO Link lets you remotely control and monitor switches 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.

    Image of Specification. Front orientation. Pressure Switches. Dual-Setpoint Electronic Pressure Switches with Digital Display.

    When these switches reach either of their two set pressures—both of which can be controlled from the display—they send digital signals to your programmable logic controller (PLC) to activate automated controls. This means you could turn on a pump at one setpoint if pressure drops too low and open a valve at another if pressure rises too high. These switches could also be used to signal an alarm before switching off a pump. For remote control and monitoring from your PLC or PC, connect an IO Link controller (not included). You’ll also need to set one of the outputs to use IO Link instead of a PNP or NPN signal.
    Change your setpoint, reset point, scaling, and other settings using the display’s buttons. An adjustable reset point means you can control the amount of pressure change before the switch resets, also known as deadband or differential. Choose anywhere within the setpoint range for your reset point. The head rotates, so you can view the display from the best angle. To reduce stress on pipes in your pressure system, secure these switches against a wall or other structure with a mounting bracket (sold separately). Use these switches with an M12 cable (sold separately) to quickly connect and disconnect them.
    All are rated IP65 and IP67, so they seal out dust and water from washdowns and brief submersion. UL and C-UL listed, all meet U.S. and Canadian safety standards.

    Accessories for Pressure Switches

    Adjustable-Reset Pressure Switches

    Choose when these switches reset to control the pressure range between when they activate and deactivate, commonly referred to as deadband and differential. You can adjust their reset point anywhere along the setpoint range. When they reach the set pressure, these switches power equipment, signal controls, or trigger alarms. They’re single pole, double throw (SPDT) and can either turn one device from off to on (normally open) or on to off (normally closed). UL listed and CSA certified, all meet American and Canadian safety standards. Those that are CE marked meet European safety standards. All protect against some corrosion.

    IP66 Enclosure Rating and NEMA 4X Enclosure Rating—NEMA 4X and IP66 rated switches can be used in dirty and wet areas exposed to washdowns. NEMA 4X switches also stand up to weather and have increased protection against corrosion, similar to 304 stainless steel.

    Adjustable-Reset Pressure Switches with Digital Display

    Image of Product. Front orientation. Contains Annotated. Pressure Switches. Adjustable-Reset Pressure Switches with Digital Display.
    Kick off automated controls, signal alarms, or activate equipment based on pressure changes while checking the pressure, setpoint, and reset point on the display. The adjustable reset point lets you control the amount of pressure change, also known as deadband and differential, before the switch resets. Adjust it anywhere within the setpoint range. Turn the external adjustment knob by hand to set pressure quickly. These are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed).
    To power the display, these switches need a separate electrical input from the one used for switching.
    These switches are IP and NEMA rated, so they’re dust tight and protected against water from washdowns and weather, as well as sprays of oil and coolant.

    Electronic Pressure Switches

    When these switches reach a set pressure, they send electronic signals to your programmable logic controller (PLC) to activate automated controls or alarms. Easily adjust the setpoint by twisting the external ring. An indicating pointer and incremental markings make sure adjustments are precise. When you have your setpoint, tighten the locking ring to prevent unintentional changes. Pair these switches with an M12 socket to quickly connect and disconnect them.
    Rated IP67, these switches seal out dust and water from temporary submersion. All are UL and C-UL listed as well as CE marked, which means they meet U.S., Canadian, and European safety standards.
    2 Circuits Controlled—1 Off (Normally Open) and 1 On (Normally Closed)
    Image of Product. Front orientation. Pressure Switches. Electronic Pressure Switches, 2 Circuits Controlled.
    Image of Attribute. Front orientation. Electronic Pressure Switches.

    Switches for two circuits function like single pole, double throw (SPDT) switches. When the switches reach the setpoint, they turn one circuit from off to on (normally open) and another from on to off (normally closed). They have an adjustable reset, which means you can control the amount of pressure change before the switch resets. This pressure difference is commonly referred to as deadband and differential. Use the second external ring to change the reset point anywhere along the setpoint range.

    Dual-Setpoint Electronic Pressure Switches for Compressed Air

    Compatible with most air systems, these switches send digital signals to a programmable logic controller (PLC) to trigger separate processes when they reach either of their two set pressures. For example, they’ll activate a compressor if the pressure is too low or a relief valve if the pressure is too high. Or use them to signal an alarm before switching off a compressor. Some of these switches also work with liquids and gases, so they can be built into hydraulic systems and wet or humid environments, such as cleaning lines.
    Monitor your pressure on the display and change your setpoints, reset points, scaling, and other settings using the buttons. An adjustable reset point means you can control the amount of pressure change before the switch resets, also known as deadband or differential. Choose anywhere within the setpoint range for your reset point. Add a panel-mount bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.
    Rated IP65, they seal out dust and water from washdowns. Switches are UL and C-UL recognized components and CE marked to meet American, Canadian, and European safety standards.
