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.
