A5S0 Overall View

A5S0 sensors – the best choice for demanding applications
The correct choice of sensor is always a prerequisite to attaining a successful solution.
Our A5S0 sensors are based on the proven Differential-Hall-Effect principle. Their low
end of 0 Hz allows to monitor 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

t Sensor short circuit proof and
t protected versus reverse error
t Accepting fine and coarse profiles,
t as gear wheels, slots, cams, holes in
t any ferrous material
BENEFITS
t Contact-free with a large air gap, so
t the potential for damage is eliminated
t Wear-free due to its unique design
tprinciple
t Maintenance-free during Lifetime,
t therefore minimized TCO
t Unsusceptible versus external
t magnetic stray fields and machine
tvibration

(>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.
To meet the particular requirements of hazardous areas we provide specialized types

which are ATEX / IECEx certified, as well as being approved for other international
standards such as UL / CSA and EAC (Russia, Kazakhstan and Belarus Customs Union).
For Zone 0 or 1 we provide an intrinsically safe implementation in conjunction with our
Isolating Barrier D461, for Zone 2 a non-sparking (non-incendive) variation is available.
