7 Field of View
The fields of view stated above are measurement diameters with an optical response of 90%.
The size of the measurement target must be sufficiently larger than the measurement diameters shown in the
above diagram.
8 Installation
The screw thread on the product is M18 x P1.0. Use the included mounting nuts to securely install this product in
a ø18mm or larger hole.
Using an item such as an L-shaped metal fitting sold on the market makes it easy to adjust the angle, etc.
Note the following when installing this product.
This product should be installed perpendicular to the measurement target.
Avoid mechanical shock to this product.
Make sure there are no heat sources around the location of this product and measurement target. Highly
reflective measurement targets may cause an error in measurement.
Do not install this product in a location where the ambient temperature is +70°C or higher or where this
product will be exposed to direct hot air.

9 Connection
Wiring to the IO-Link Master
Use the M12 4-pin connector cable to connect the IO-Link master and this product.
10 Measurement
1. Ensure that the connection is correct before applying power to this product.
2. Check that this product operates properly on the IO-Link master.
* There may be some errors in the measured temperature when the temperature of this product is unstable,
such as immediately after this product is installed.

- 11 -
Emissivity (ε)
The emissivity is the rate of the energy emitted from the surface of the object. All objects possess a particular
emissivity that changes according to the object’s surface conditions and temperature. Setting the emissivity of
the measurement target on this product allows for more precise measurements.
Objects with a low emissivity (e.g. the surfaces of shiny metallic objects) reflect the surrounding temperature
since they are highly reflective. For such targets, nearby heat sources other than the measurement target will
lead to incorrect measurements due to these temperatures being reflected. In these situations, countermeasures
such as blocking all heat sources other than the measurement target should be implemented. Taking into
consideration usage convenience, the emissivity can be set up to 1.20 on this product.
11 Maintenance
Lens
Dust, dirt, and scratches on the lens can cause incorrect measurements. In case of dirty lenses, please remove
the dust on the lens with a blower for lens cleaning, etc. If the dust or dirt cannot be removed with a blower,
lightly wipe the lens with a cotton swab or special lens cleaning cloth using a small quantity of ethyl alcohol.
Housing
If the housing becomes excessively dirty, wipe it with a soft cloth using a small quantity of ethyl alcohol.
Calibration
OPTEX FA recommends having calibration performed annually. Contact an OPTEX FA sales representative.
12 Process Data
The process data exchanged by this product with the IO-Link master via IO-Link cyclic communication is shown
below.
IO-Link process data is transmitted in big-endian format, so the following table is also expressed in this format.
By default, OPTEX FA’s IO-Link master UR-MS and UR-ES series convert IO-Link process data to little-endian
format before transmitting it to the field network. When using these products, refer to the following table by
reversing the byte order.

Details corresponding to [Select process data]
Process input data is assigned as follows according to [Select process data].
Value Details
0: Peak temperature hold Highest temperature during measurement
1: Valley temperature hold Lowest temperature during measurement
2: Internal temperature Temperature of this product
The [Select process data] options “Peak temperature hold” and “Valley temperature hold” operate as shown in
the following diagrams.
Use the [System command] “Reset hold” to reset the held temperatures.

Alarm output
Upper limit/lower limit/hysteresis
Alarm output turns on when the measured temperature exceeds the upper alarm limit.
This output turns off when the measured temperature falls below (upper alarm limit minus alarm hysteresis).
Alarm output turns on when the measured temperature falls below the lower alarm limit.
This output turns off when the measured temperature exceeds (lower alarm limit plus alarm hysteresis).
Alarm timer
When [Alarm timer function] is set to [Delay], the output is delayed for the time set with [On delay time] and [Off
delay time] as shown with “Delay” in the above diagram.
When [Alarm timer function] is set to [One-shot], output is generated just for the time set with [One-shot time] as
shown with “One-shot” in the above diagram.

64 0 R/W 2 0.950
Value Details
0.100 to 1.200 Sets the emissivity of the measurement target. The value is set in units of 0.001.

Response time
Index number Subindex number Read/Write Data byte count Default value
65 0 R/W 1 1.0
Value Details
0.1 to 10.0 Applies moving average processing to the measured temperature. A longer response
time increases the delay before the measured temperature is obtained, but the
measured value will be more stable. The response time is set in units of 0.1 seconds.
Emissivity teaching
Index number Subindex number Read/Write Data byte count Default value
66 0 R/W 2 —
Value Details
0.0 to 400.0 (°C) Calculates the emissivity so that the measured temperature equals the set
temperature.
When this value is read, the current measured temperature is returned.
32.0 to 752.0 (°F)
If the target temperature is known but the emissivity of the measurement target is not, the ratio can be calculated
and set with the following procedure.
1. Ready the measurement target for measurement. Ensure that the ambient temperature is stable. (Wait
approximately 10 minutes after power on.)
2. Write the target temperature in index 66, [Emissivity teaching].
3. Wait 100 ms.
4.Read index 66, [Emissivity teaching]. The procedure has been successful if the measured temperature is close
to the target temperature.
An error result is stored in index 59, [Teaching status], when:
The automatically calculated emissivity is not in the range of 0.1 to 1.2.
The target temperature of the measurement target is close to the ambient temperature, making it difficult to
detect the difference between these temperatures.
As an example, with an emissivity of 0.95 and an ambient temperature of 25°C, calculation is possible if the
difference between the ambient and target temperatures is 5°C or more.
