Contact Q-Globle for more information. WARNING: Not to Be Used for Personnel Protection Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Overview The Q-Global sensor emits a well-defined beam of high-frequency radio waves from an internal antenna. Some of this emitted energy is reflected back to the receiving antenna. Signal processing electronics determine the distance from the sensor to the object based on the time delay of the return signal. The sensor can be configured to two independent sensing zones. The two sensing zones are factory pre-set to default distance; The sensor is plug-in ready for immediate operation. The sensitivity is precalibrated at the factory, assuming that the sensing field will be clear of obstacles. Specifications Range The sensor is able to detect a proper object(see Detectable Objects) from 1 to 60m, depending on target Detectable Objects Static objects, Moving objects. Operating Principle Frequency modulated continuous-wave (FMCW) radar Operating Frequency 77-81GHz Supply voltage 12V/24V DC Supply Protection Circuitry Protected against reverse polarity Delay at Power-up Less than 100 seconds Output Protection Protected against short circuit conditions Construction Front Housing: PPO Rear Housing: Aluminium Alloy Access Cap: PVC Operating Temperature -40-85 Environmental Rating IP67 Connections 8-pin Waterproof terminal Certifications CE FCC E-MARK Beam Angles Long distance mode: azimuth 120°,elevation 50°. Short distance mode: azimuth 80°,elevation 90°. Dimensions All measurements are listed in millimeters, unless noted otherwise. Beam Patterns Antenna configuration 0 mainly detects dynamic targets Antenna configuration 1 mainly detects static targets 1:Weak Object(RCS = -10) 2:Rider (RCS = 0) 3:Car(RCS = 10) 4:Larger Truck(RCS = 20) Windows The Q-Global sensor can be placed behind a glass or a plastic window, but the configuration must be tested and the distance from the sensor to the window must be determined and controlled prior to installation. There is typically a 20% signal reduction when the sensor is placed behind a window. Polycarbonate at 2mm thickness performs well in most situations, but the performance depends on filler materials. Thinner (0 to 1.5mm) windows have high reflection. The amount of reflection depends on the material, thickness, and distance from the sensor to the window. Locate the sensor in a position of minimum reflection from the window, which will repeat every 1.9 mm of distance between the sensor and the window. The position of maximum reflection from the window repeat between the minimums, and decrease in effect until the window is approximately 150mm away. Consult the factory for pre-tested window materials which can be used at any distance without issue. Additionally, the face of the window should be protected from flowing water and ice by use of a flow diverter or hood directly above the window. Falling rain or snow in the air in front of the window, light water mist, or small beads on the face of the window are typically not an issue. However, a thick, continuous surface of water or ice directly on the face of the window can be detected as a dielectric boundary.

For the most recent version of any documentation, refer to:www.q-solutions.com.cn FCC Warning This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: --Reorient or relocate the receiving antenna. --Increase the separation between the equipment and receiver. --Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. --Consult the dealer or an experienced radio/TV technician for help. FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment . This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment should be installed and operated with minimum distance 25cm between the radiator& your body.
