Rotational speed sensor A5S0DS4

Hall effectnon-contactthreaded

Sensor A5S0DS4 for detection of rotational speed and direction of rotation with two phase-shifted speed signals and highest safety requirements up to SIL3 Key Features SIL3/IEC 61508:2010 certified by TÜV Detection of rotational speed and direction of rotation with two phase-shifted speed signals in non-hazardous areas Speed range from 0 Hz to 12 kHz Dual Channel, the output displays the rotational speed as a twin-track frequency signal (phase shifted) Suitable for external direction detection with enhanced safety 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 machine vibration Sealed stainless steel enclosure > 200 bar pressure to the 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 Benefits 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 Can not be damaged by faulty wiring Almost every target profile can be used A5S0 sensors do not influence each other, no mounting distance in between is required
