We had a similar enquiry from a customer running a stone-masonry saw where the encoder was getting hit with constant dust, grit and the occasional water spray from the cutting process. The Hengstler ACURO AR63 shares the same rugged design family as the AR62 and is built to keep working through that kind of abuse.
This looks simple, but the AR63’s numbers are worth checking properly – it handles 300 N of axial and radial shaft load, 200 g shock and 20 g vibration, and is rated up to IP69K, so it’s built for high-pressure wash-down as well as everyday dust and grit. It uses magnetic sensing rather than an optical disc, with a wear-free, battery-less electronic multi-turn count, so there’s no gearbox or battery to maintain over the machine’s life.
In actual application, the AR63 gives up to 28-bit combined resolution, runs on SSI, CANopen or Analog interface, and is rated across a broad -40°C to +100°C range with 32 mm mounting depth in an aluminium housing. Like the AR62, it’s used across wind turbines, ships, commercial vehicles, presses, wood-processing machinery and stone masonry equipment.
From our experience, before we quote this, we would normally check the interface your controller needs (SSI, CANopen or Analog), the shaft configuration for your mounting, and whether you actually need the IP69K wash-down rating for your environment. Hope this helps.
