Sensor A5S1DS3 for detection of rotational speed and direction of rotation in Hazardous Areas Zone 0 or 1 and highest safety requirements up to SIL3
To meet the specific requirements of hazardous areas (Ex Zone 0 or 1), 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). A5S1 sensors, in conjunction with our Isolating Barrier D461, provide an intrinsically safe implementation to meet these specific requirements.
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.

The BRAUN Differential-Hall-Effect based Sensors A5S
♦ 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
♦ Cannot be damaged by faulty wiring
♦ Almost every target profile can be used
♦ A5S1 Sensors do not influence each other, no mounting distance in between is required
