Differential Hall Effect Speed Sensor







The correct choice of sensor is always a prerequisite to achieving a successful solution. Our A5S speed sensors are based 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 A5S sensors especially suited to 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)


♦   Detection of rotational speed in non hazardous areas
♦    Speed range from 0 Hz up to 25 kHz (response time < 20 microseconds)
♦   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 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
