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.

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.

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.

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.
