Differential-Hall-Effect Speed Sensors Ex nA (non-sparking) Series A5S1…-n
To meet the specific requirements of hazardous areas, we provide specialized types certified for ATEX, UKEX, IECEx, and other international standards such as UL/CSA and EAC (the Eurasian Customs Union with Russia, Kazakhstan, and Belarus). For hazardous areas (Zone 2), a non-sparking (non-incendive) variation is available. No Isolating Barrier D461 is required.
The correct choice of sensor is always a prerequisite to achieving a successful solution. Our A5S sensors are based on the proven Differential-Hall-Effect principle. Their low end of 0 Hz allows monitoring the machine down to zero speed. In addition, they are contact-free, wear-free, and maintenance-free. Furthermore, they are unsusceptible versus external magnetic stray fields and machine vibration. These characteristics make the series of A5S sensors especially suited to all applications where high accuracy and reliability are at a premium. In contrast, other sensors like magnet-inductive or static Hall-sensors do not meet these demands.
The sensors virtually can detect any steel profile: fine or coarse, helical or straight gear wheels, nuts or pole wheels with small or large cams. Depending on the application, the speed range spans an area from a stationary state up to 25 000 pulses per second (0 Hz…25 kHz).
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.
