Specification notes
Q1: What is the TAKEX US-S25AN?
A: The US-S25AN is an M18 cylindrical reflective ultrasonic distance sensor with an integrated amplifier and distance-proportional analog voltage output.
Q2: What is the sensing range of the US-S25AN?
A: Its detecting distance is 60 to 250 mm.
Q3: What output does the US-S25AN provide?
A: It provides a voltage output proportional to distance, rated at 2.4 V±0.5 V at 60 mm and 10.0 V±0.5 V at 250 mm.
Q4: What is the minimum resolution of the US-S25AN?
A: The minimum resolution is 2 mm, including 80 mV ripple.
Q5: What power supply does the US-S25AN require?
A: It operates from 24VDC ±10% with ripple of 10% or less.
Q6: Can the US-S25AN measure liquid level?
A: Yes. It can measure a liquid surface without contact and is used for applications such as oil-level detection and checking liquid content through a bottle opening.
Q7: Can the US-S25AN be used for height measurement?
A: Yes. Its proportional analog output can be used to determine the height of medicines or other workpieces.
Q8: Is the US-S25AN suitable for semiconductor equipment?
A: Yes. TAKEX lists silicon wafer detection from underneath as one of its application examples.
Q9: What should be considered during installation?
A: Keep the mounting nut tightening torque at 0.98 N·m or less. The sensor has an IP54 protective structure, and water drops should not remain on the sensing head.
Q10: How do I determine whether the US-S25AN is suitable for my application?
A: Confirm that the required distance falls within 60–250 mm, that the target can adequately reflect ultrasound, and that the control system supports its proportional voltage output and 24VDC power supply.
