Overview
The Banner S18UUAQ ultrasonic sensor is a straight-housing proximity sensor designed for reliable distance measurement and presence detection in industrial automation systems. This model offers 0-10V DC analog output and operates across a 10-30VDC supply voltage range, making it compatible with most 12VDC and 24VDC control systems. The 18mm compact form factor and integrated 5-pin M12 quick-disconnect connector simplify field installation and sensor replacement.
