The electromechanical temperature controller manufactured by Leitenberger (part number: 04.35) is specifically designed for front panel installation, featuring a 3-hole front flange, combining precision with high functionality. This model is known for its easy installation and robust stainless steel construction, ensuring long-term reliability. The device is an ideal choice for demanding industrial applications where accuracy and dependability are key.
This device follows the principle of „Quality Made in Germany,” ensuring the highest level of measurement and control performance.
This temperature controller has several features that set it apart from competitors:
Robust Design: The high-quality stainless steel housing guarantees a long service life and corrosion resistance even under harsh operating conditions.
Easy Readability: The dual display (actual value black, setpoint red) on a clear white background with black markings ensures quick and precise reading.
High Accuracy: The Bourdon tube measuring system without bimetallic compensation ensures extremely accurate temperature measurement.
Wide Measuring Range: The adjustable measuring range from -80°C to +380°C provides flexibility for controlling various process temperatures.
Setpoint Adjustable From the Rear: The setpoint adjustment is made on the back of the device, which facilitates fine-tuning of built-in units without obstructing the display.

The device is reliable for Bourdon tube measuring system built in. The lack of bimetallic compensation means that the measurement is exclusively based on the temperature measured by the temperature-sensing element, which is ideal for applications where the influence of ambient temperature on the measuring mechanism should be minimized. The scale length is approximately 240 degrees, which ensures excellent resolution within the full measuring range. The display accuracy is according to the DIN 16203 standard classified as Class 2 which guarantees reliability according to industrial standards.
The thermostat is equipped with a built-in switch, which allows for automatic control of processes when the set temperature value is reached.
Switching Capacity: The relay can handle a load of 5 Amperes at 125 Volts, or 3 Amperes at 250 Volts AC voltage, at frequencies between 40 and 60 Hz.
Hysteresis: Around the switching point, a hysteresis of approximately $pm 2%$ (as a percentage of the full measuring range) is provided to ensure that the switch does not „breathe” (switch on-off too quickly) near the set value, thereby increasing system stability and the life of the contacts.
Connectors: Connections are made using standard 6.3 mm flat connectors, in accordance with the EN 60730 standard, which ensures compatibility and safe wiring.
The device basically IP 53 provides a degree of protection for the housing (protected against dust and protected against spraying water), while the connectors IP 00 have protection (no protection).
Optional Protection: If protective caps are fitted for the connectors, the full degree of protection IP 55can be raised to , which offers increased protection against dust and water jets, making the device ideal for use in dustier or wetter environments.
The product is also available with fixed settings, which have a factory pre-set switching point and limit value at the maximum set value. In this case, user setting options for the switching point are not available.
This electromechanical temperature controller can be used excellently in:
Refrigeration technology: Precise temperature control of cold rooms, cold storage units, and industrial refrigeration equipment.
Industrial Heating Systems: Monitoring and control of process temperatures where a reliable switching function is required.
Mechanical Engineering: Temperature monitoring and safety shut-off for built-in equipment.
HVAC Technology: Management of temperature control points in larger systems.
Leitenberger is committed to quality, and this product is the result of German engineering expertise and precision. For further information or if you are interested in custom configurations, please contact our sales team.
