The traditional vacuum switch. When these switches reach a set vacuum, they power equipment, signal controls, or trigger alarms. They’re larger and easier to wire than our compact vacuum switches. All 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). NEMA rated, they protect against some corrosion but shouldn’t be used outdoors. They all meet safety standards.

Switches with a cover protect against impact and keep dust off the switch.

Specifically made for air systems, these switches send signals to your programmable logic controller (PLC) to trigger processes when they reach a set vacuum. Use them to turn equipment on or off, activate automated controls, or signal alarms. Check the vacuum 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 vacuum change before the switch resets, also known as deadband or differential. Choose anywhere within the setpoint range for your reset point. All switches meet at least one American, Canadian, or European safety standard.

Switches with 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 rated switches protect against dust and light rinses.

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

Choose these switches when you need reliable switching but not high accuracy. When they reach a set vacuum, they turn equipment on and off, signal automatic controls, or trigger alarms. They 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). All meet American and European safety standards since they're UL recognized components and CE marked.

Control the amount of vacuum change between when these switches activate and deactivate by adjusting when they reset. Also known as adjustable deadband and differential switches, you can set the reset point anywhere within the setpoint range. Use them to power equipment, signal controls, or trigger alarms when they reach the set vacuum. They’re single pole, double throw (SPDT) and can either turn one circuit from off to on (normally open) or on to off (normally closed). All meet safety standards.

Switches with an on/off indicator let you monitor the equipment it’s controlling 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.

Trigger two different processes in vacuum applications by sending signals to a programmable logic controller (PLC) when these switches reach one of their two set vacuums. Designed specifically for air systems, they can turn on a vacuum pump if the vacuum is too low or a valve if the vacuum is too high. Or use them to signal an alarm before switching off a pump. Check the vacuum on the display and change your setpoint, reset point, scaling, and other settings using the buttons. An adjustable reset means you can control the amount of pressure change before the switch resets. This pressure difference is commonly referred to as deadband and differential. Choose anywhere within the setpoint range for your reset point.

Rated IP65, these switches seal out dust and water from light rinses. They meet American, Canadian, and European safety standards since they’re UL and C-UL recognized components as well as CE marked.

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 (normally open) or from on to off (normally closed).

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.

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.

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.

When these 3-A certified switches reach a set pressure or vacuum, they trigger controls and alarms in food-processing, pharmaceutical, and biotech lines. They have a sleeve to shield internal parts from water and contaminants. Their surfaces are polished and their seams are continuously welded, so cleaning is easy and there’s little room for bacteria to grow. Made of 316 stainless steel, these switches stand up to harsh cleaners and sanitizers without rusting. Rated IP67 and NEMA 6, they’re dust tight and protected from washdowns and temporary submersion.

They connect using the same quick-clamp fittings (also known as tri-clamp fittings) that are common in sanitary lines, because they’re easy to take apart for cleaning. This end has a diaphragm that protects from corrosion and covers threads to keep them clean. The diaphragm is filled with 99.5% pure USP food-grade glycerin, reducing the risk of contamination if the diaphragm fails. The serial number is laser etched on the diaphragm to reduce crevices.

Twist the adjustable setpoint ring to make quick changes. These switches 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).

All have a certificate with a traceable lot number and material test report.

Specifically made for compressed air and gas systems, these transmitters remotely monitor pressure and vacuum. Also known as transducers, they convert both pressure and vacuum into an electrical signal that can be interpreted by receiving devices, such as remote displays, and motor speed controls. They also have two digital PNP switch outputs that you can connect to your programmable logic controller (PLC) to activate automated controls or alarms when a set pressure or vacuum is reached. Change settings with the buttons on the digital display.

For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's pressure or vacuum range and output signal. As pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure or vacuum range.

UL and C-UL recognized components, CSA certified, and CE marked, they meet American, Canadian, and European safety standards.

Transmitters with current output connect using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.

Transmitters with voltage output connect using three wires. Two wires connect to the power supply, and a separate wire sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.
