8 m Range Ultrasonic Sensor
The Banner QT50UDB is a rectangular proximity sensor that detects objects from 200 mm to 8 m using a time-of-flight ultrasonic beam. It operates on a 10-30 V dc supply and provides two discrete outputs configurable as NPN or PNP. The sensor is intended for industrial automation and electrician tool applications requiring non-contact distance measurement. Its chemical-resistant PBT housing suits harsh environments where standard sensors may degrade.
Thermals Noise and Power Draw
The unit draws power from a 10-30 V dc source with a 1500 ms delay at power-up before the outputs become active. Temperature effects are specified as uncompensated 0.2% of distance per °C and compensated 0.02% of distance per °C. Output saturation voltages remain below 0.2 V for NPN at 10 mA and below 1.2 V for PNP at 10 mA, rising to 0.65 V and 1.65 V respectively at higher loads. No fan or active cooling is present; the device runs silently.
Build Quality Connectors and Mounting
The housing uses PBT material rated for chemical resistance and meets vibration requirements per MIL-STD-202F Method 201A at 10 to 60 Hz with 0.06 inch double amplitude and mechanical shock per IEC 60947-5-2 at 30 G for 11 ms. A fixed 2 m cable with five conductors terminates the connection; no quick-disconnect option is fitted. LED indicators provide local status feedback. Push-button adjustments allow configuration without a PC. The rectangular form factor mounts on flat surfaces using standard hardware.

Questions about this item
How do I mount and wire the QT50UDB rectangular housing, and which step causes the most problems?
Mount the PBT rectangular housing securely, connect the 5-pin 2 m cable to a 10-30 V dc supply, then press the push-button adjustment to set the 200 mm to 8 m sensing window; the step most often missed is allowing the 1500 ms power-up delay before the first reading.
What maintenance or replacement will the QT50UDB need over time?
The sensor has no moving parts; keep the ultrasonic face clean for reliable time-of-flight readings and verify the LED indicators stay lit — if output saturation drifts beyond NPN < 0.2 V at 10 mA or PNP < 1.2 V at 10 mA, replace the unit.
What is the first limit that appears when the QT50UDB runs continuously in a 10-60 Hz vibration environment?
Temperature drift is the first limit: uncompensated shift reaches 0.2 % of distance per °C, while the compensated spec holds to 0.02 % per °C; both exceed the vibration and 30 G shock ratings before those become an issue.
