BRAUN传感器A5S0DD0具体参数表

Differential-Hall-Effect based Sensors for Detection of Speed in Non Hazardous Areas Series A5S0DD0 / A5S0DS0 The BRAUN Speed Sensors Series A5S are TÜV certified for SIL3 acc. IEC 61508:2010 and therefore meet the high SIL3 standards. The correct choice of sensor is always a prerequisite to achieving a successful solution. Therefore BRAUN A5S0 sensors base on the proven Differential-Hall-Effect principle. Their low end of 0 Hz allows monitoring the machine down to zero speed. They are contact-free, wear-free, maintenance-free and unsusceptible versus external magnetic stray fields and machine vibration. These characteristics make the series of A5S0 sensors especially suited for all applications where high levels of accuracy and reliability are at a premium. In contrast, other sensors like magnet-inductive or static Hall-sensors do not meet these demands. Each sensor in the series is available in various lengths and diameters and comes with a choice of connections. However, functionally all sensors have the same characteristics. The stainless steel sensor housing is sealed at the front and is pressure resistant (> 200 bars). A flat shaft is available or with a screw-in thread M12x1, M14x1, M14x1,5, M16x1, M16x1,5, M18x1, M18x1,5, M22x1, 5/8-18UNF-2A. Customized dimensions and thread specifications are possible. To meet the specific requirements of hazardous areas we provide specialized types which are certified for ATEX/IECEx, as well as for other international standards such as UL/CSA and EAC (the Eurasian Customs Union with Russia, Kazakhstan, and Belarus). For Ex Zone 0 or 1 we provide an intrinsically safe implementation in conjunction with our Barrier D461, for Ex Zone 2 a non-sparking (non-incendive) variation is available. A5S0 sensors – the best choice for demanding applications KEY FEATURES SIL3/IEC 61508:2010 certified by TÜV Detection of rotational speed in non hazardous areas Speed range from 0 Hz to 25 kHz Air gap to the target / pole wheel up to 2.5 mm (depending on the profile size) Temperature range -40…+125 °C (-40…+255 °F) Differential principle diminishes the influence of external magnetic stray fields and of machine vibration Sealed stainless steel enclosure > 200 bar pressure to the sensor tip Available for connection via tight plug, or with firmly attached cable (PVC or Teflon® insulated) Powerful square wave output signal equally high over the entire speed range Sensor short circuit proof and protected versus polarity error Accepting fine and coarse profiles, as gear wheels, slots, cams, holes in any ferrous material BENEFITS Contact-free with a large air gap, so the potential for damage is eliminated Wear-free due to its unique design principle Maintenance-free during Lifetime, therefore minimized TCO Unsusceptible versus external magnetic stray fields and machine vibration Operates down to zero speed Can not be damaged by faulty wiring Almost every target profile can be used A5S0 Sensors do not influence
