TTK70 absolute linear encoders from Sick is one of the most flexible and compact linear measuring systems on the market. The TTK70 absolute linear encoder fulfils just about every communication wish. SSI/SinCos output, Profibus, DeviceNet, and CANopen are all covered.

With its small design for a measurement length of up to 4m, the TTK70 absolute linear encoder is an ideal solution for a range of applications that require linear position detection. Because of its high degree of process dynamics, it is a high performance encoder.

Offers high degree of process dynamics

For TTK70 absolute linear encoders, not only are the dimensions limited to the essentials, but so is net weight. In this way, in any given operating scenario, e.g. on a linear axis, the encoder minimizes the additional mass to be accelerated or decelerated, thus making a high degree of process dynamics achievable – especially since the admissible travel speeds have been designed high enough to match.

Maximum fieldbus flexibility

Featuring the interface adapter modules for Profibus, DeviceNet, and CANopen, the TTK70 absolute linear encoder, as the smallest device of its kind, offers optimum integration into the control system of a machine or plant. The modules not only permit various connection options but if required, they can be changed without replacing the encoder. Due to the SinCos output, users opting for the version with SSI interface benefit from the real-time capability of the TTK70.

More compact is impossible 

TTK70 absolute linear encoders consist of a reading head and an absolute coded magnetic tape, 10 mm in width and up to 4 m in length, that serves as a measurement scale. The rugged metal housing of the reading head, including the plug connection, is barely bigger than a matchbox, currently making it the smallest system with fieldbus interface on the market.
