Ranco has provided a wide array of thermostats and sensors for HVAC under-hood use since 1937. Most applications today use either electronic thermostats or sensors that come in a wide array of physical configurations.


APPLICATIONS

  • HVAC compressor and clutch cycling.
  • Condenser fan control.
  • Evaporator freeze protection.

SPECIAL FEATURES  
  • Both electronic sensors and thermostats provide higher temperature sensing accuracy and are integral parts of today's computerized automotive systems.
  • Sensors provide an economical way to sense temperature when sufficient ECM memory is available.
  • Electronic thermostats can provide complete control when ECM memory is needed for other uses.
  • Both fin and air sensing element styles are available.
  • Ranco's electronic thermostats can switch loads ranging from ECM logic level currents to full clutch loads.
  • Electronic thermostats are fully sealed for under-hood use and applications.
  • Ranco is QS-9000 certified for all automotive thermostats and sensors.
  • Ranco designs are EMI resistant.
  • Many different packaging and termination options are available to meet a wide range of application needs. Contact Ranco North America marketing for further assistance.

L53 Sensor

The L53 sensor is available in a wide range of configurations and is used primarily as a freeze protection sensor on evaporators. The L53 is used in conjunction with an OEM's ECM as an input device.

E56 Electronic Thermostat

The E56 electronic thermostat is primarily used as an HVAC clutch cycling thermostat where fin temperature sensing is desired. It has a 5.0 amp relay output and can be produced with a number of different termination configurations.

E57 Electronic Thermostat

The E57 electronic thermostat is primarily used as an HVAC clutch cycling thermostat. The E57 thermostat is suited for switching ECM logic currents or low power relay loads and can be produced with a number of different termination configurations. E57 thermostats are used in applications where fin temperature sensing is desired.

E59 Electronic Thermostat

The E59 electronic thermostat is primarily used as an HVAC clutch cycling thermostat. The E59 thermostat is suited for switching ECM logic currents or low power relay loads and can be produced with a number of different termination configurations. E59 thermostats are used in applications where air temperature sensing is desired.
