A Wide Variety of High-precision
Temperature Sensors
• Previous models with M3 screw connections
have been joined by new models with ferrules to
help reduce wiring work.
• A Temperature Sensor for Packaging Machines
that accurately measures seal temperature has
been added.
• The type, shape, length, and terminal shape can
be selected to match the temperature to be
measured, location, and environment.

Dimensions
Dimensions are given in millimeters, except for the length (L), which
is provided in centimeters.
Permissible Temperature in Dry Air
Terminal box: The permissible temperature is 0°C to 100°C.
Note: The length L is in centimeters, but “40” is 40 millimeters.

E52-PR@C-N
Dimensions
Dimensions are given in millimeters, except for the length (L), which is provided in centimeters.
Note: The length L is in centimeters, but “150” is 150 millimeters.
Therefore, for the E52-PR75C-N: L = 75 (cm), the protective tubing length L − 150 = 750 − 150 = 600 mm.
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-N 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.

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.
Model Information
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.

Safety Precautions
Precautions
• Make sure that the protective tubing material is suitable for the
sensing object. Otherwise, the Temperature Sensor’s protective
tubing may be corroded by the sensing object, preventing
temperature measurement.
• Do not subject the Temperature Sensor’s protective tubing to
excessive vibration, shock, or weight. Platinum resistance
thermometers in particular use extremely fine resistance elements.
Using these Temperature Sensors in locations subject to
mechanical shock or vibration may result in broken wires.
Lead Wire Extension
• Platinum Resistance Thermometers
Use lead wires for extension with the same resistance and same
length for each of the three wires. The resistance of the lead wire
will affect the indicated temperature when extended. Therefore,
use wires with thick cores. (OMRON does not supply lead wires for
extension.)
• Thermocouples
Always use compensating conductors for thermocouples when
extending the lead wires.
Use a compensating conductor designed for the connected
thermocouple. If you use a different type of compensating
conductor from the thermocouple or if you use normal copper wires
to extend, correct temperature measurement will not be possible.
Also, do not connect positive and negative incorrectly.
• Thermistors
Use cables with thick core wires for the lead wires used for
extension. The lead wires do not have polarity.
• Regardless of the type of Temperature Sensor used, resistance to
noise will be reduced if the leads are extended. Never extend the
lead any further than necessary.
Correct Use
• Select a location for installing the Temperature Sensor in which the
temperature distribution of the sensing object will not change.
• Make sure that the length of the Temperature Sensor’s protective
tubing is sufficient to touch or insert into the sensing object. The
length of metallic protective tubing must be at least 20 times its
diameter, and the length of non-metallic protective tubing must be
at least 15 times its diameter.
The insertion length of the special model for packaging machines
(E52-CA
@
AY S
@
)
is 8 mm or longer.
• Do not repeatedly bend the Temperature Sensor at the same point.
The minimum allowable bending radius of sheathed Temperature
Sensors is approximately five times the protective tubing diameter.
Bending part of the sensor at an acute angle and then extending
again may result in broken internal wires or cracks in the element.
Do not bend the soldered sections.
The minimum allowable bending radius of the special model for
packaging machines (E52-CA@AY S@) is twice the protective
tubing diameter.
• Do not bend the protective tubing while measuring low temperatures,
which will cause the protective tubing to become fragile.
• Do not bend sheathed Temperature Sensors to within 100 mm of
the end to protect the sensing section.
Bending work can be performed on any part that is 8 mm or more from
the tip of the special model for packaging machines (E52-CA
@
AY S
@
).
•
Do not allow the temperature of the section connecting the
protective tubing and lead wire to exceed 70°C for exposed-lead
models or 100°C for heat-resistive models.
The special model for packaging machines (E52-CA
@
AY S
@
) can
be used at temperatures of up to 260
°
C.
• Do not allow the temperature of the terminal box to exceed 100
°
C
for exposed-terminal models or 90
°
C for enclosed-terminal models.
• Do not subject the ceramic protective tubing of high-temperature
thermocouples to sudden heating or cooling. Ceramic protective
tubing has a low resistance to thermal shock. Either preheat the
protective tubing or gradually heat to the required temperature.
• Do not use standard lead wires in locations subject to strong
bending stress or on moving parts.
• Thermocouples with crimp terminal
Use the crimp terimal only as a secondary means of securing the
thermocouple. The thermocouple junction of the thermocouple is at
the crimped section of the crimp terminals, so a temperature
difference occurs between the screw fixating section and the
thermocouple junction. Confirm the difference in temperature
between the location that is to be measured and the temperature
measured by the thermocouple in advance at the actual application
temperature.
Mounting
1. Install explosion-proof models according to the applicable laws
and regulations regarding explosion proofing.
2. Sheathed Temperature Sensors with long protective tubing are
coiled for shipping. Straighten the tubing by unwinding it in the
opposite direction, without twisting it.
3. Do not excessively bend the section connecting the protective
tubing to the lead wires of exposed-lead wires models. Do not
insert this section into the sensing object.
4. Do not pull the lead wires with force. Doing so may cause broken
wires at the connected section.
5. When measuring at high temperatures that cause the protective
tubing to warp, either insert the Temperature Sensor vertically or
use an appropriate means to hold the Temperature Sensor in
place.
6. To obtain more accurate values, maintain the temperature of the
exposed protective tubing to prevent heat loss through heat
dissipation.
7. If inductive noise is generated in the Temperature Sensor due to
power lines or other source, either change the installation position
of the Temperature Sensor and lead wires or provide a shield for
the lead wires.
8. Use airtight Temperature Sensors for applications using sensing
objects below room temperature, to prevent condensation within
the protective tubing and faulty insulation.
9. Do not use the Temperature Sensor in locations that may expose
the terminals to water or other liquid.
10.Temperature Sensors are precision devices. Do not subject the
Temperature Sensors to shock. Take particular care with products
that have ceramic components (ceramic protective tubing,
platinum resistance thermometers).
11.Do not use ultrasonic cleaning or otherwise subject platinum
resistance thermometers to extreme vibration. Doing so may
cause wires to break within a short time. For such environments,
consider using sheathed thermocouples, which have a superior
vibration-resistant construction compared with platinum resistance
thermometers and may be more suitable for the required
application, depending on the level of vibration.
12.The life of the protective tubing will be significantly shortened when
measuring the temperature of dissolved metals. Select protective
tubing material to suit the type of dissolved metal to be measured.
13.Use the following installation methods for applications measuring
the temperature of fluids.
(a)Install the Temperature Sensor vertically to the flow in tubes
with relatively large diameters that enable deep insertion.
(b)Install the Temperature Sensor on a diagonal against the flow in
tubes with slim diameters that do not enable deep insertion.
(c)Install the Temperature Sensor into the convex section of a
bend if the tubing diameter is even thinner than in (b).
Use an installation design that provides sufficient strength margin.
