Photoelectric sensor reliably detects clear objects
The Q26 Series photoelectric sensor from Banner Engineering features a polarized retro coaxial design to provide reliable detection of clear, translucent or opaque objects, including mirror-like surfaces.
With the ability to operate at very short distances and deliver precise leading edge detection, the Q26 is suitable for 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.
The Q26 features a compact cubic shape with 20 mm mounting hole spacing, enabling quick installation in tight locations. Additionally, the sensor’s coaxial optics permit operation over a wide range of distances with the reflector mounted as close as 5 mm for applications with restricted spaces. The Q26 includes a LO/DO switch to control the output type, and a single turn potentiometer to adjust detection sensitivity. Equipped with a Health Mode output for application monitoring, the Q26 communicates operation and connection status—allowing the user to ensure reliable sensor performance.
The Q26 operates on 12-30V dc with a response speed of 250 microseconds. The sensor is also protected against damage from potential mis-wiring during installation and transient voltage spikes during operation.
