1 Long-Distance Ultrasonic Displacement s UN Series Unaffected by the color or material of the target object, ultrasonic sensors achieve long sensing distances using direct reflection. High sensing accuracy Resolution: 0.3 to 0.6 mm Long sensing distance UNAM50I 6121/S14 Sensing range: 400 to 2,500 mm FEATURES Long sensing range with high resolution Distance measurement with the top resolution level in the industry. Direct measurement output of 0 10 Vdc or 4 20 ma. UNAM30I6103 Sensing range: 100 to 700 mm Resolution: 0.3 mm UNAM50I6121/S14 Sensing range: 400 to 2,500 mm Resolution: 0.6 mm No adjustments needed if the color of the target object changes. 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.

3 GLOSSARY 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 setting A range upper limit setting that can be programmed with Teach-In. Near limit setting A range lower limit setting that can be programmed that can be with Teach-In. Minimum setting interval The minimum interval between the two settings.

Indicator modes Sonic level Analog output Target position Orange LED lit Orange LED blinking Good Small margin Measurement output Within set range Orange LED out Insufficient Indefinite * Red LED lit 4 20 ma or 0 10 Vdc Between blind range upper limit and range near limit setting * 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 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 Output 4mA 0V 20mA 10V Sensing distance 5

6 Output When setting 0 Vdc or 4 ma output, place the target far from the sensor. 20mA 10V Distance greater than 2 times the largest range limit setting 4mA 0V Distance greater than 4 times the largest range limit setting Sensing distance 2.2 Factory defaults 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. 0.1 m < 0.1 m < 3. Handling precautions 4. Influence by diffuse reflection from surrounding objects 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. Target Sound-insulating barriers 5. Wiring precautions 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. 6
