The new AFM60 absolute multiturn encoder available from Sick Stegmann has a 30-bit resolution and features greater ruggedness. Its smaller brother, the AFS60 absolute single-turn encoder has a high resolution of 18 bits. The two new product families are suitable for harsh operating conditions in which both maximum accuracy and availability are important.
The AFS60 absolute single-turn encoder has a maximum single-turn resolution of 18 bits.
Supplemented with 12-bit multiturn resolution, the single-turn encoder becomes the AFM60 multiturn encoder with an “absolute” top value of 30 bits.
The AFM/AFS60 series are characterised by extreme sturdiness for optical systems. Firstly, this is due to the nickel code disk. Given the same resolution, it is more robust than code disks made of glass. Compared to plastic code disks, AFM/AFS60 series offer better resolution and temperature-resistant and can be used at ambient temperatures from -20°C to +100°C.
In addition, the expanded 30mm shaft bearing of the AFM/AFS60 series ensures greater ruggedness than encoders with blocked ball bearings. Even at maximum operating speeds, the enlarged bearing distance leads to an optimum truerunning and lack of vibrations.
Each device in the AFM/AFS60 series, with 60mm housings, is available as a clamping or a servo-flange version for solid round shafts. Users can choose between M12 or M23 plug connections, or opt for cable exits that can be used radially or axially – with various connector lengths. This reduces the number of different variants and simplifies installation when space is limited.
Both the AFM60 and the AFS60 encoders have an SSI interface. In addition, they can be programmed using the same programming tool, which has already proved itself in use with the DFS60 series from Sick Stegmann. Now, incremental, absolute single-turn, and absolute multiturn encoders can be parameterised with a single programming tool.
