The AH103 absolute encoder from W+S Messsysteme is a single-turn encoder with a through-hole hollow shaft in size 103 mm, designed for particularly large shaft diameters ranging from 30 to 45 mm. The hollow shaft design allows for the direct mounting of solid drive shafts without a shaft coupling and ensures backlash-free, precise position detection. A reference run following a power failure is not required.
The aluminium housing is optionally available in stainless steel and complies with protection class IP65. The connection is radial. Supply voltage: 5 VDC or 8–30 VDC. Operating temperature range: −20 to +70 °C, optionally up to +100 °C.
Push-pull (HTL) and RS422 (TTL) are available as signal outputs. Communication takes place via a parallel output, ensuring direct and reliable signal transmission to the higher-level control system.
The AH103 is particularly suited for use in large drives, heavy-duty conveyor systems, rolling mills, presses, printing presses and machine tools with large spindle or shaft diameters that require a direct and robust encoder connection.
