An adjustable reset lets you control the amount of temperature change, also known as deadband and differential, before these switches reset. Twist the rings to select the setpoint temperature and reset temperature anywhere within the setpoint range. When they reach the set temperature, they send an electronic signal to your programmable logic controller (PLC) to turn equipment on or off. Because they control two circuits, they turn one device from off to on (normally open) and another from on to off (normally closed). An LED illuminates to indicate they’re switching. These switches are often used in control and automation in hydraulics, pneumatics, air-conditioning, and refrigeration applications. Made of stainless steel, they resist corrosion and chemicals.

Install these switches directly into tanks, pipelines, and other process components using their threaded probe. They have a micro M12 plug connection and are compatible with micro M12 sockets, so you can quickly connect and disconnect them. After selecting your setpoint, tighten the locking ring to prevent unintentional changes.

IP rated, these switches seal out dust and water from temporary submersion. They also meet U.S., Canadian, and European safety standards.

Send signals to trigger two different processes, each with their own set temperatures. For example, use one setpoint to turn a heater on and off at one temperature and another to activate an alarm if the temperature rises too far above the cutoff point. Twist the outer ring to adjust your setpoints—no need for tools. After choosing your setpoint, tighten the locking ring to prevent unintentional changes. Once the setpoint is reached, an LED illuminates, indicating the switching status. The threaded probe installs directly into tanks, pipelines, and other process components.

These switches send an electronic PNP signal to your programmable logic controller (PLC), so they’re often used in control and automation applications. They have a micro M12 plug connection and are compatible with micro M12 sockets, allowing you to quickly connect and disconnect the switch.

They are rated IP67 for protection from dust and temporary submersion.

Instead of disassembling your system for inline installation, thread these flow switches onto a mounting adapter (sold separately) and insert them into a pipe tee or pipe outlet. They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. These switches are accurate in any mounting orientation.

IP65 rated switches protect against dust and washdowns. IP67 rated switches withstand temporary submersion.
