FAQ:

1.What is the deviation of the detection accuracy of T30UXUAQ8 on the surface of measured objects made of different materials?

Core Reference Accuracy Parameters

Parameter	Value	Notes
Linearity	0.25% of distance	At full scale 1000mm, linear deviation ≤2.5mm
Repeatability	≤±0.5mm	Under short-term stable working conditions
Analog Resolution	0.1% of distance (1.5 min)	Approx. ±1mm at 1000mm
Temperature Effect	0.02% of sensing distance/°C	After temperature compensation, approx. 0.2mm deviation per °C at 1000mm

Typical Deviation for Different Materials (Within 100-1000mm range)

Test Object Material	Surface Characteristic	Typical Deviation	Notes
Metal (Steel/Aluminum)	Flat/High reflectivity	Reference deviation (±0.5‑1mm)	Strong reflected signal, minimal error, close to nominal accuracy
Rigid Plastic	Smooth/Medium reflectivity	±1‑2mm	Stable signal, slightly higher deviation than metal
Glass/Acrylic	Transparent/Smooth	±1.5‑3mm	Multiple reflections to be considered, optimizable via teach mode
Wood/Cardboard	Rough/Medium-low reflectivity	±2‑3mm	Surface texture causes echo dispersion, reduced accuracy
Foam/Soft Materials	Porous/Low reflectivity	±3‑5mm	Severe acoustic wave attenuation and weak signal, gain adjustment required
Liquid (Water/Oil)	Flat/Surface fluctuation	±2‑4mm	Affected by liquid surface ripples, wave guide tube recommended
Powder/Granules	Loose/Low reflectivity	±3‑5mm	Prone to dust interference, installation angle optimization required

2.What is the working condition of the device corresponding to each status of the T30UXUAQ8 three-color LED?

LED Color	Status	Corresponding Working Condition
Green	Steady On	Sensor powered on, in normal measurement state, no faults, stable analog output
Green	Flashing (approx. 1Hz)	Sensor in teach mode (touch/remote teaching in progress), recording target parameters
Yellow	Steady On	Unstable detection signal (e.g. low reflectivity, critical distance, environmental interference), measurement accuracy may decrease, check the measured object or environment recommended
Yellow	Flashing (approx. 2Hz)	Sensor in parameter configuration/update state, or detection distance close to blind zone/upper range limit
Red	Steady On	Sensor fault (e.g. abnormal power supply, output short circuit, internal circuit fault), analog output may be interrupted, shutdown and troubleshooting required
Red	Flashing (approx. 1Hz)	Detection out of range/blind zone, or temperature out of compensation range, measurement results unreliable
Red + Yellow	Alternating Flashing (continuous)	Teaching failed (e.g. no valid echo, parameter conflict), re-perform teaching required
Off	—	No power supply, wiring error or LED damaged, check power supply and M12 connector connection first

3.What is the core difference between T30UXUAQ8 and T30UXIAQ8 (4-20mA current output)?

Comparison Item	T30UXUAQ8	T30UXIAQ8 (4-20mA)	Core Impact
Analog Output Type	0-10V voltage output	4-20mA current output	Determines compatibility with PLC/controller analog input modules
Load Capacity	Maximum load resistance varies with supply voltage (≤2.4kΩ at 24V)	≤1000Ω (24V supply)	4-20mA is better for long-distance transmission with strong voltage drop resistance
Anti-interference Performance	Voltage signal susceptible to electromagnetic interference, accuracy degrades in long-distance transmission	Current signal with strong anti-interference, suitable for transmission over 100m	Current output is more stable in complex industrial electromagnetic environments
Wiring & Safety	Common ground and shielding required, no short-circuit self-recovery	With cyclic short-circuit protection, higher wiring fault tolerance	Current output is more adaptable to harsh industrial sites
Signal Zero/Full Scale	0V = blind zone (100mm), 10V = upper range limit (1000mm)	4mA = blind zone (100mm), 20mA = upper range limit (1000mm)	Different logic for zero offset and fault diagnosis
Response Time	Selectable 45ms/105ms	Selectable 45ms/105ms	Consistent response performance with the same configuration
Sensing Range & Accuracy	100-1000mm, linearity 0.25% of distance, repeatability ≤±0.5mm	100-1000mm, linearity 0.25% of distance, repeatability ≤±0.5mm	Identical core measurement accuracy parameters
Physical Specifications	M30 thread, T-shaped right-angle housing, 4-pin M12 QD connector	M30 thread, T-shaped right-angle housing, 4-pin M12 QD connector	No difference in installation and mechanical adaptation
