Temperature Sensor
E52
A Wide Variety of High-precision
Temperature Sensors
• Ideal for the thermal input devices of Temperature Controllers.
• Select from a wide variety of Temperature Sensors according to
the temperature to be measured, location, and environment,
and also according to the type and shape of the terminal.
• General-purpose, low-cost, and exclusive models are available.
Refer to Safety Precautions for All Temperature
Controllers.

Dimensions
Dimensions are given in millimeters, except for the length (L), which is provided in centimeters.
Note: 1. The length L is in centimeters, but “40” is 40 millimeters.
Therefore, for the E52-P20C, L = 20 (cm), the protective tubing length L − 40 = 200 − 40 = 160 mm.
2. The length L is in centimeters, but “50” is 50 millimeters.
Therefore, for the E52-P75C: L = 75 (cm), the protective tubing length L − 50 = 750 − 50 = 700 mm.
3. Terminal box: The permissible temperature is 0°C to 80°C.

Note: 1. Lead Wire (Compensating Conductor)
•Standard (−20°C to 70°C):
Fully vinyl-covered with seven 0.3-dia. conductors (0.5 mm
thick) and external dimensions of 3.2 × 5.0.
•Heat Resistive (0°C to 150°C):
Fully glass-wool-covered with seven 0.3-dia. conductors
(0.5 mm thick) with external shield of stainless steel and
external dimensions of 2.9 × 4.6
The heat-resistive lead wires cannot be used in locations
exposed to water or other liquids.
•Lead Wire Length (M): 1, 2, 4, or 8 m
2. The sleeve resists temperatures ranging between −20°C and 70°C
for standard models and 0°C and 100°C for heat-resistive models.

Dimensions
Dimensions are given in millimeters, except for the length (L), which
is provided in centimeters.
Model Information
Note: The permissible temperature given for the protective tubing is
higher than 1,400°C, but the permissible temperature of the
thermocouple element wire is only 1,400°C. Therefore, the
protective tubing of the E52-PR@C can withstand high
temperatures momentarily to the levels given in the table as
exceptions, but the element wire will deteriorate quickly if the
thermocouple is used regularly at temperatures that exceed the
permissible temperature for the element wire.
Use wiring terminals that fit M4 screws.

3. The thermocouple is not of airtight
construction.
4. OMRON recommends that the tip of the
thermocouple is touching the sensing
object.

Cut a thread into the workpiece, and screw in the
thermocouple while pushing in so that the tip
makes complete contact.

Model Information
Note: The Compression Fitting is not of airtight construction. Do not use the Compression Fitting for applications in which the exposure of the
sensing object will cause problems.
The compression fitting is a screw that adjusts and secures the
insertion length of Temperature Sensors with the above protective
tubing diameters.
The material of the Compression Fitting is SUS304 with internal
fixing beads made of brass.

Compensating Conductors
The material of the Compensating Conductor is the same as or similar to that of the Thermocouple. Therefore, the Thermocouple can be connected
to the Compensating Conductor just as if the length of the Thermocouple is to be extended. A standard model for a temperature range between
−20°C and 70°C and two types of heat-resistive models for a temperature range between 0°C and 150°C are available.
Be sure to use the compensating conductor for the extension of the length of the thermocouple.

Note: 1. Compensating Conductors with lengths, increased in units of a meter, up to 100 meters are available on request. Specify lengths above
100 meters in units of 100 meters. The maximum length depends on the product. Contact your OMRON representative for details.
2. It has the same waterproof characteristics as the standard model (fully vinyl-covered) and can be used at high temperatures.
