Compact absolute linear encoder features a choice of interfaces
Sick is launching the TTK70, a compact absolute linear encoder that is designed for positioning robotics and machine tools or as a motor feedback system for linear motors. This high-performance magnetic encoder is said to provide a reliable alternative to fragile optical scales, with sub-micron resolution and an accuracy of +/-10 microns.Featuring a small yet robust read head that is barely bigger than a matchbox, the TTK70 encoder is not only compact but also easy to install. In addition, the TTK70 encoder is versatile, with a wide range of interface options such as SSI/SinCos, Profibus, Devicenet and Canopen, enabling simple integration into PLC-based installations. The TTK70 is also available with a Hiperface interface, enabling it to deliver highly dynamic linear motor feedback.
With a high level of resistance to dust, dirt and wet environments, due to magnetic operating principles and IP65 rating, the TTK70 delivers high reliability even in harsh operating conditions.
The encoder is suitable for use in robotic handling systems, metal forming, cutting and processing PCB print and assembly, as well as flatbed printers and medical scanning equipment. It operates at up to 10m/s and can measure up to 4m in length.
Darren Pratt, an encoder specialist with Sick (UK), comments: "The TTK70 is a unique offering. It combines the highest level of accuracy that you would expect from a magnetic linear encoder, with the largest choice of interfaces, in a compact easy-to-install package at a competitive price point."
