Banner Engineering has introduced the Q26 series photoelectric sensor to its line of clear object detection sensors. Featuring a polarised retro-coaxial design, the Q26 is an ideal solution for difficult clear object detection applications, such as filling and bottling machines, flat glass or LCD manufacturing, pharmaceutical vials or bag filling machines, or any high-speed application where positioning is critical. With its compact cubic shape and coaxial optics, the Q26 is designed for tight locations. The cubic shape with 20 mm mounting spacing enables quick installation and the coaxial optics allows the sensor to operate over a wide range of distances with the reflector mounted as close as 5 mm in space constrained applications.
“Banner has several sensors capable of reliable clear object detection, but the Q26 Series is optimised for clear object detection, with a design focus on simple user set-up and adjustment,” says Dennis Smith, technical marketing manager at Banner Engineering. “The Q26 delivers both the sensitivity required for reliable clear object detection and the robust rejection of light from mirror like objects to prevent a false detection. The coaxial optical design delivers the additional benefit of precise leading edge detection, making it useful for many high speed applications in the bottling, canning and packaging industries.”
Several features of the Q26 series help distinguish it from other photoelectric sensors with clear object detection capabilities. The Q26 includes a LO/DO switch to control the output type and a single turn potentiometer to adjust the detection sensitivity. It also includes a Health Mode output for application monitoring. The sensor operates from 12-30 VDC with a response speed of 250 microseconds. Finally, the sensor is protected against damage from accidental mis-wiring during installation and transient voltage spikes during operation.
