| | | Area scanner For surface monitoring of doors and gates using area industrial scanners, Pep-perl+Fuchs offers the most extensive product line on the market thanks to their years of specialisation in the area. The product line includes sensors with fan-shaped detection fields and automatic adjustment to the background, sensors for row installation in narrow profile housings, compact sensors for surface detection in different detection field sizes, and counting sensors for counting people with direction detection. All sensors offer numerous possibilities for the configuration of the monitoring area, e.g. configurable detection ranges, user-switchable detection fields, and a choice between background suppression and background evaluation. The product line includes designs for direct and alternating current, with transistor or relay outputs, light/ dark switches, and configurable timing functions. | | The product line includes designs for direct and alternating current with relay outputs, with configurable light/dark switching, and designs for use outdoors. Elevator light grids When operating elevators, it is necessary to prevent incoming or outgoing passengers from being touched or even injured by closing doors. The AL20/AL40 light grid by Pep-perl+Fuchs was designed especially for convenience elevators and is the first product of this kind with a 7-segment professional display. This greatly simplifies operation and service work. The series includes light grids with 20 or 40 infrared beams and different profile widths. With an operating range of four meters, 1650-mm-high protection fields with up to 194 crossed beams, starting at a height of 20 mm above the floor, can be implemented. In the area close to the floor, smaller beam gaps and an asymmetrical beam pattern ensure that even small objects, like the points of professional shoes, are detected reliably. Standard-conformal to the EN81-70 are available light grids up to 1800 mm protection field. Distance measurement device The time required for a beam of light to cover the route transmitter - object -receiver - is a measure of the distance to the object. One method for the indirect distance measurement is the so-called pulse time measurement. Pulse time is the time the light beam takes to be reflected back to the source. By measuring this time the distance between the source and the object can be calculated using the speed of light. | | |
| | | For the monitoring of the space before elevators and doors, as a cost-effective impulse sensor for any automatic system and signal sensors for open entry-ways, anywhere where people are to be detected, passive-infrared motion detectors can be used, since they react to changes in the heat images when a person moves within the detection field. Using professional zoom technology and apertures, the shape of the monitoring field can be set precisely. The product line includes designs for direct and alternating current. Radar motion detectors | | |
| | | Depending on the radar module, the user can choose the sensor's large range of detection settings using a simple manual configuration or by hand held Professional remote control. Functions like direction detection, distinguishing between people and vehicles, professional filter functions to prevent interferences, and professional timer functions give these sensors a broad spectrum of applications. Latest versions now offer closing edge monitoring with an additional field. | | |
