The compact all-in-one systems

The compact U-ONE(-SAFETY)-Compact universal encoder systems for speed and position monitoring improve performance by making optimal use of permitted speed ranges and fast and precise positioning. They combine different functions in a robust housing and are therefore ideal for the simple modernization of existing solutions when continuing to make use of legacy cabling or when there is no space in the switchboard for electronic function modules. The all-in-one systems are directly mounted onto the shaft that needs to be monitored. They therefore require no additional mechanical components such as distribution gears, distribution couplings or speed increasing gears and additionally offer higher accuracy. The simple parameter input and preset function after maintenance work ensure high system availability. The systems are optionally available with all components certified for use in safety applications with requirements up to SIL 2 / PL d.
