Q2 Miniature Sensors

A slim Q2X fixed-field sensor can be fitted onto a 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. 

A Q2F flat pack fixed-field sensor can be easily fitted in the confined spaces of automated optical inspection machines used for detecting defects on printed circuit boards (PCBs), such as missing components or soldering errors. With its thin, 4-millimeter housing, the sensor can be mounted just 10 millimeters underneath a PCB. When the inspection is complete and the board moves along, the sensor sends a signal indicating the area in front of the camera is clear and ready for the next PCB.

• Accurately detect targets while ignoring objects beyond a fixed cutoff distance
• Quickly commission with no configuration or setup required
• Simplify installation while still having mounting flexibility with 10–75 mm sensing ranges available with no configuration required
• 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

The Q2X Laser Measurement sensor with adjustable background suppression can be taught to have a cutoff distance slightly away from the back wall allowing 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. 

• 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 

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.

• Simplify installation with fewer components and less wiring; no retro target or receiver required    
• 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

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 retroreflective sensing, the Q2X can detect microwell plates of any color, shade, or reflectivity. 

• 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

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. 

• With high excess gain and no dead zone, reduce false and missed detections
• 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
