Long sensing distance UNAM50I 6121/S14
Distance measurement with the top resolution level in the industry. Direct measurement output of 0–10 Vdc or 4–20 mA.
Long sensing range with high resolution
Because of the ultrasonic sensing method, there is no need to change settings for a new target object color.
Long sensing distances with high accuracy will continue.
No adjustments needed if the color of the target object changes.

Blind range (St)Range near the sensor in which the target cannot be detected reliably. In this range, however, there is a chance of detection due to multiple reflection of ultrasonic waves between the sensor and target.
Scanning range far limit (Sde)The far limit of the sensing range.
Sensing range (Sd)The area between the blind range far limit and the scanning range far limit.
Far limit settingA range upper limit setting that can be programmed with Teach-In.
Near limit settingA range lower limit setting that can be programmed that can be with Teach-In.
Minimum setting intervalThe minimum interval between the two settings.

1. Indicator modes
* The orange LED could be out for any of the following reasons:• There is no target.• The target is out of range.• The target is within the blind range.• The ultrasonic reflection from the target is too weak.
2. Operating the Teach-In button
Set the scanning range as follows.• Press the button for 2 to 6 seconds until the indicator blinks alternately orange and red.
• Release the button and the indicator will begin to blink red.• Place the target at the 0 Vdc or 4 mA output position and press the button. The indicator begins to blink orange.
• Place the target at the 10 Vdc or 20 mA output position and press the button to complete setup. The interval between the two set points is linearly interpolated.
2.1 Setting a scanning range
Use the Teach-In button for setup. Setup should be completed within five minutes after power-up. The settings are fixed after five minutes to
prevent them from being accidentally changed during regular operation. Even after the power is turned off, the settings are saved.

There are two ways of setting the scanning range,
depending on the target position.
• When setting 0 Vdc or 4 mA output, place the target near the sensor

• Route the cable separately from power lines or though a separate
conduit. Otherwise, induction may cause incorrect operation or
damage.
• If a switching regulator is used for the power supply, connect the
frame ground and ground terminal to ground. If the sensor is used
without grounding, faulty operation may occur due to switching
noise.
• Although the sensor has a miswiring protection circuit, incorrect
wiring involving the input/output terminals may cause damage.
• Diffuse reflection from surrounding objects because of ultrasonic
diffusion or sidelobes may cause incorrect detection. If measurement
is incorrect, consider the following countermeasures: keep the
sensor away from the surrounding objects, use sound-absorbing
materials like sponge, or install sound-insulating barriers.
• When setting 0 Vdc or 4 mA output, place the target far from the sensor.

3. Handling precautions 4. Influence by diffuse reflection from surrounding objects
5. Wiring precautions
It is possible to revert the settings to the factory defaults by either of
the following methods:
1.
• Press the button for more than 6 seconds until the indicator rapidly
blinks alternately orange and red.
• Release the button, and the indicator will light orange and red at
the same time for 2 seconds. The sensor has been reset to the
factory defaults.
2.
• Set a scanning range without a target. The indicator will rapidly
blink alternately orange and red for 2 seconds. The sensor has
been reset to the factory defaults.
