Banner Engineering QS18UPAQ8 Photoelectric Sensor

QS18UPAQ8 is a compact ultrasonic distance sensor from Banner's World-BEAM QS18U Series, featuring Teach Mode for straightforward setup. It detects objects in a 50 mm to 500 mm range (about 1.97 to 19.69 inches) and delivers a PNP output when an object is within range, powered by 12 to 30 V DC. The part number 73156 identifies this exact QS18UPAQ8 configuration within Banner's catalog, and Banner lists it as part of the QS18U ultrasonic family on its product pages. Built-in temperature compensation helps preserve measurement accuracy as ambient conditions change, contributing to stable performance in a variety of production environments. The QS18UPAQ8's compact form factor supports easy mounting in tight spaces, and its ultrasonic sensing modality makes it suitable for tasks where non-contact detection is required. Operating from 12 to 30 V DC, it is compatible with many standard industrial controls, and its 50–500 mm sensing range makes it suitable for short- to mid-range detection needs on busy automation lines.
