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.

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.

Switches with an on/off indicator tell you the status of your equipment, letting you monitor your equipment even when it’s out of sight.

All protect against some corrosion. NEMA 1 rated switches should only be used indoors. 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.

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.

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 rated switches protect from dust and light rinsing.

Add a square panel-mount bracket (sold separately) to mount these switches to a control panel for easy viewing and adjusting.

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.
