BANNER Q2X Miniature Photoelectric Sensors

IMPORTANT INFORMATION

Space-saving photoelectric sensor with short- and long-range models

Ideal for installation in precise machinery and tight industrial spaces, Banner’s compact Q2X Series features the widest range of sensing modes for any automation application.

Fixed-Field

Simplify installation while still having mounting flexibility with 15, 30, and 50 mm sensing ranges available with no configuration required
Consistently detect challenging targets with best-in-class background suppression
Avoid crosstalk when mounting multiple sensors in close proximity due to the advanced crosstalk immunity algorithm

Challenge

Applying pressure-sensitive labels to packages requires lowering a tamp head to the product and applying enough pressure to adhere the label without damaging the product.

Solution

A Q2X fixed-field sensor can be fitted onto the labeling machine’s tamp head to sense targets at a fixed distance, regardless of the product’s color. The sharp 15 mm cutoff distance allows the tamp arm to lower to a consistent distance away from the target, even with products of differing heights. Once the tamp head is close enough to the product, it slows until it makes contact. It applies the appropriate amount of pressure to adhere the label, then rises to repeat the process.

Adjustable-Field

Ignore objects in the background with an adjustable cutoff distance between 18 mm and 150 mm
Detect dark and challenging targets using powerful emitters with high excess gain
Detect precise features with the small, bright-red LED or Class 1 laser emitter
Avoid crosstalk when mounting multiple sensors in close proximity due to the advanced crosstalk immunity algorithm

Challenge
Silicone wafers can be an extremely challenging target to detect, due to their dark, shiny surface. Ensuring correct positioning is vital for these delicate substrates while they are moved and lifted through their processes. Size is also a limiting factor in the machine design.

Solution
The high excess gain of the adjustable-field Q2X allows it to reliably detect dark wafers. The tight minimum object separation can trigger the machine to move the next wafer into position as soon as the previous one is out of the way. And the small form factor easily fits into the machine without getting in the way

Laser Measurement

Measure farther with the industry’s longest sensing range for a sensor in a compact housing
Sense the most challenging targets like dark or shiny poly bags with a powerful infrared laser with best-in-class excess gain
Employ in many applications by consolidating to one sensor model with the array of sensing modes, including background suppression, window mode, and dual mode
Integrate easily into most control systems and access measurement values, delay timers, and advanced diagnostics via IO-Link
Provide real-time visual feedback to machine operators without using a PLC by integrating the PulsePro output directly into Banner Pro lights

Challenge
Within warehouses, retroreflective sensors are often used to detect blocked chutes before they can disrupt throughput. However, a single package stuck blocking a beam can cause a false jam and shut down equipment.

Solution
The Q2X Laser Measurement sensor with adjustable background suppression can be used. A cutoff distance taught slightly away from the back wall allows temporarily stuck packages to be ignored without disabling the entire chute. The built-in delay timing (available over IO-Link) can be implemented to wait until there is a real jam before shutting down the machine. One customer was able to reduce false jams by more than 90 percent and improve their throughput

Polarized Retroreflective

Reduce installation time with an easy-to-align, bright-red LED
Detect targets moving at high speeds with the 600 μs response time
Sense light, dark, and shiny targets farther away with industry-leading 3.3 m range
Mount the reflector as close as 3 mm from the face of the sensor for ultra short range applications*

*40 mm x 19 mm reflector required (model: BRT-40x19A)

Challenge
Medical and scientific laboratories need a method to ensure that their microwell plates are accurately positioned in testing machines. Polarized retroreflective sensors work well for leading-edge detection, but many testing machines have a small footprint and are already crowded with internal components.

Solution
The Q2X polarized retroreflective sensor is small enough to fit inside many types of machines that cannot accommodate larger sensors. In addition to its reduced size, the sensor offers a fast response time of 600 μs, which ensures accurate positioning relative to the known speed of conveyors. By using retro reflective sensing, the Q2X can detect microwell plates of any color, shade, or reflectivity

Opposed

Simplify installation with an easy to align, large visible spot
Decrease false and missed detections by ignoring most dust and debris
Emitter and receiver can be up to 3 m ( 10 ft) apart and will reliably detect objects as small as 4 mm anywhere within the beam

Opposed Emitter

Opposed Receiver

Challenge
Before a suspension strut assembly can proceed down the line, the presence of all parts must be verified. However, Tier 1 automotive assembly machines may not have enough physical space to house a larger or even average-sized sensor for this verification.

Solution
The miniature housing of the opposed-mode Q2X can be fit into most assembly machines. Once the Q2X is installed, its 4.3 mm effective beam can accurately sense whether the top cap of the strut is present; deciding if it can advance to the next stage of assembly.
