Our A5S1 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.
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.
♦ Detection of rotational speed in Hazardous Areas Zone 0 or 1
♦ 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 b ar 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
♦ 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
