Washdown On/Off Temperature Controllers
Rated IP65 and NEMA 4X to seal out water and dust, these temperature controllers turn your equipment on and off in areas with frequent washdowns. They're the simplest type of temperature controller, so they switch your heater or other device fully on or off without a middle state when they reach a given temperature. These controllers work great as alarms and in systems that can't handle rapid switching or have slow temperature changes. However, you shouldn't use them in processes that require precise control over temperatures.
To read temperature, these controllers use a highly sensitive thermocouple or RTD probe (not included). Their mechanical relay actuates circuits directly. All are SPDT (single pole, double throw) and can turn one circuit from off to on (normally open) or on to off (normally closed). Since these controllers reset automatically, they turn off and on again as the temperature fluctuates. Use the keypad to set the actuation point, reset point, and other settings. Mount them into instrument panel cutouts.
These controllers have UL recognized components and are CSA certified and CE marked, so they meet American, Canadian, and European safety standards.

Electronic Temperature Switches with Digital Display
Micro
M12 Plug
A digital display makes it easy to monitor the temperature and control when these switches turn heating equipment on and off. They have an adjustable reset, so you can change the temperature range between when they activate and deactivate, commonly referred to as deadband and differential. Use the keypad to adjust the setpoint and reset point anywhere on the setpoint range. They produce an electronic signal that is often used to communicate with a programmable logic controller (PLC), so they're common in control and automation applications. Install them directly into tanks, pipelines, and other process components using their threaded probe.
These switches have a micro M12 plug, so you can quickly connect and disconnect them.
Rated IP65 and IP67, these switches protect against dust and water from washdowns and temporary submersion. They’re also UL listed, C-UL listed, and CE marked, so they meet U.S., Canadian, and European safety standards.
