Banner's photoelectric sensors emit a beam of light that detects the presence or absence of items and targets made of most materials — including shiny, dark, clear, and multicolored ones — as well as changes in surface conditions. When the emitted light is interrupted or reflected by the item, the change in light patterns is measured by a receiver, and the target is recognized. These sensors are available with an extensive selection of styles (e.g., self-contained, long-range, heavy-duty, and compact), housings, mounting options, sensing modes, and detection ranges.
They also perform a wide variety of tasks, exhibit very fast response times, and are widely used in industrial manufacturing, material handling, and packaging applications in markets spanning food and beverage to medical.
The Q2X Series miniature photoelectric sensors, for example, provide unparalleled versatility and performance with five different sensing modes engineered to accurately detect even the most challenging targets over short- and long-range distances. They also offer compact housings optimized for today's increasingly space-constrained industrial automation applications. Banner recently added two new sensing modes, laser measurement and fixed-field, to the original three: adjustable-field, polarized retroreflective, and opposed.
The new Q2X Laser Measurement Photoelectric Sensors feature a powerful beam with the longest sensing range of any compact sensor in the industry. They can sense the most challenging targets, including dark and shiny poly bags, using powerful infrared lasers with best-in-class excess gain and support a wide range of applications with various sensing modes, including adjustable background suppression, window mode, and dual mode. Their IO-Link capabilities make it easy to integrate into most control systems and access measurement values, delay timers, and advanced diagnostics, and they can also provide real-time visual feedback for machine operators without using a PLC by integrating Banner's Pulse Pro outputs directly into its Pro Series LED lights.
The new Q2X Fixed-Field Photoelectric Sensors support mounting flexibility and 15, 30, and 50mm sensing ranges without any configuration or setup, which enables the fastest-possible commissioning. They also accurately detect challenging targets with best-in-class background suppression that ignores all objects beyond a fixed cutoff distance and avoid crosstalk when multiple sensors are mounted in close proximity.
Q2X Adjustable-Field Photoelectric Sensors have small form factors equipped with powerful, bright-red LED or Class 1 laser emitters with high excess gain to accurately detect dark and otherwise challenging targets. They are easy to install with just a few components and minimal wiring; they reliably ignore background objects with cutoff distance options spanning 18–150mm; and they avoid crosstalk when multiple sensors are mounted in close proximity.
Q2X Polarized Retroreflective Photoelectric Sensors have a compact form factor equipped with a bright-red, easy-to-align LED that reduces installation time and reliably detects high-speed targets with a 600µs response time, which ensures accurate positioning relative to the known speed of conveyors. They also precisely detect light, dark, and shiny targets, including microwell plates of any color, shade, or reflectivity, with an industry-leading 3.3m range and ultra-short-range targets as close as 3mm from the sensor face.
Q2X Opposed Photoelectric Sensors have a miniature housing optimized for assembly equipment and they exhibit high excess gain, don't have a dead zone, and ignore most dust and debris to mitigate false and missed detections. Their emitters and receivers can be up to 3m apart and will reliably detect objects as small as 4mm anywhere within the beam. They are also easy to install and align given their large, visible spot.
