Description

Sensor A5S1DS3-n for detection of rotational speed and direction of rotation in Hazardous Areas Zone 2 and highest safety requirements up to SIL3 The BRAUN Speed Sensors Series A5S1 are TÜV certified for SIL3 acc. IEC 61508:2010 and therefore meet the high SIL3 standards. To meet the specific requirements of hazardous areas (Ex Zone 2), we provide these specialized types which are certified for ATEX, UKEX, IECEx, as well as for other international standards such as UL/CSA and EAC (the Eurasian Customs Union with Russia, Kazakhstan, and Belarus). The correct choice of sensor is always a prerequisite to achieving a successful solution. Therefore, BRAUN A5S1 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 A5S1 sensors especially suited for 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. 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 (>200bar). 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.
