## Summary description

Compact thermostat sensor with a normally closed (NC) output, set to actuate at 70°C and reset at 55°C. Designed for temperature monitoring and control in HVAC, industrial equipment or electrical cabinets. Provides reliable switching based on temperature thresholds to protect components, trigger fans or control heating elements. Model code EB1937148488#.

## Long description

Thermostat Sensor (Normally Closed Output) 70°C setpoint, 55°C reset is a compact temperature control device designed to switch contacts when the monitored temperature reaches 70°C and to return to its original state after cooling to 55°C. The sensor provides a normally closed (NC) output, which opens at the setpoint temperature and closes again once the temperature falls below the reset threshold. It is intended for integration into HVAC systems, electrical enclosures and industrial equipment where reliable thermal switching is required to protect components or to control auxiliary devices such as fans and heaters.
Advantages
The device offers a defined switching behaviour with separate actuation and reset temperatures to avoid rapid cycling near a single threshold. Its compact form factor simplifies installation in confined spaces, and the normally closed contact configuration suits fail-safe or power-off default scenarios. The thermostat sensor is built for stable mechanical switching action and consistent repeatability across many cycles, helping to maintain temperature-dependent protection and control functions in varied environments.
Suitable for
 Temperature monitoring and overheat protection in electrical cabinets and control panels
 Activation of fans or ventilation when internal temperatures rise
 Control of heaters or thermal cut-out in industrial machines
 Integration into HVAC systems for auxiliary safety or control loops
Key specifications
 Output type: normally closed (NC) mechanical contact
 Actuation (setpoint) temperature: 70°C
 Reset temperature: 55°C
 Operating principle: mechanical thermostat switching
 Installation: compact form suitable for panel or enclosure mounting
How to use
Mount the thermostat sensor in the location where temperature measurement is representative of the protected area, ensuring good thermal contact with the monitored surface or airflow. Wire the NC contact into the control or protection circuit following the equipment wiring diagram so that the circuit opens when the device reaches 70°C and closes when it cools to 55°C. Verify correct orientation and secure mechanical fixing to avoid vibration or loosening. Perform initial functional testing by applying heat and allowing the sensor to actuate and reset to confirm reliable switching behaviour.
Usage recommendations
For accurate operation, avoid mounting the sensor near strong heat sources that do not reflect the typical ambient temperature of the protected equipment. Allow for the fixed temperature differential between actuation and reset when designing control logic, and ensure contacts are rated for the intended switching current and voltage. Regular visual inspection and functional testing during maintenance cycles will help ensure continued reliable performance.
