WORLD-BEAM® QS18 Series Photoelectric Sensors

Banner Engineering WORLD-BEAM® QS18 Series Photoelectric Sensors offer a 10VDC to 30VDC voltage range and bright LED status indicators visible from 360°. These sensors feature IP67-rated ABS housing and LED and coaxial lenses. The coaxial optics detect clear and mirror-like surfaces and operate at short distances from the reflector, enabling precise leading-edge detection. Providing simple pushbutton operation, the user aligns the sensor with the reflector, pushes and holds the button for 2 seconds, and begins inspecting. Banner Engineering WORLD-BEAM QS18 Series Photoelectric Sensors offer a variety of sensing methods, including adjustable background suppression, expert opposed-mode with IO-link, mechanically adjustable foreground suppression, and clear-object detection.
