Compact ultrasonic sensor for short-range detection
The Banner QS18UNA is an 18 mm rectangular sensor with an M18 mounting thread and a 2 m cable. It operates on 12-30 V dc supply and provides a single NPN discrete output rated at 100 mA. The housing uses ABS material with LED indicators for status.
TEACH button simplifies range setup
Pressing the TEACH button sets the switching point between the 50 mm minimum and 500 mm maximum sensing distance. Analog resolution and discrete repeatability are specified at 0.7 mm. The sensor powers up in 300 ms and requires no PC configuration.
50-500 mm sensing range defines the application fit
Time-of-flight ultrasonic measurement covers targets from 50 mm to 500 mm. Temperature drift is +/- 0.05% per °C from -20 °C to +50 °C and +/- 0.1% per °C up to +60 °C. Vibration and shock ratings meet MIL-STD-202F Method 201A and IEC 60947-5-2 30G half-sine requirements.

Questions about this item
Does the ABS housing or the 2 m cable need scheduled replacement?
The ABS housing and the 2 m cable have no scheduled replacement interval; only the teach button and LED indicators may wear with repeated use.
What limits continuous operation — the 100 mA output ceiling or the 12–30 V dc supply range?
The 100 mA discrete output limit is reached before the 12–30 V dc supply range becomes a constraint.
How much heat or noise does the sensor produce when powered all day at 12–30 V dc?
The ultrasonic sensor runs silently with negligible heat; power-up delay is 300 ms and temperature effect is ±0.05 %/°C from −20 °C to +50 °C.
