Flexibly Adaptable Encoder System
New developments in robotics, automation and many other rotative applications are aiming for ever more compact designs and often cannot be implemented using the standard components available on the market. To prevent restricting the scope of design for the customer, Siko offers a new flexcoder technology – an encoder system comprising a sensor and rule that can be adapted to the position and shape of the application.
The flexibility of adaptation of flexcoder technology allows it to be built exactly into the user’s design. The key factor is that both the sensor and the rule can be adapted. The available Siko standard can also be applied by a magnet ring or encoder. This allows, e.g., the compact sensor mount to be adopted, and modification is required only to the attachment of the rule on the user’s shaft. With other applications, a standard Siko magnet ring is used and the mounting of the flexible sensor array and the evaluation and interface electronics are adapted to the user’s specific fixing options in the housing. Since the electronics can be both bent and stacked, integration can be very compact. Thanks to these adaptations to the encoder and rule with regard to the shaft diameter and the fixing options available, the application can be designed more compactly and more uncompromisingly.
Users solutions – flexible and quickly realized
Siko can use its in-house technologies for the rule technology and the electronics. The realization time in which the system is customized to the user specification is planned skillfully. From the idea through to the series solution, the project is implemented directly and in short time intervals.
High-resolution, absolute – technical performance
The MSAC200 issues absolute position feedback as soon as it is switched on. For this the SSI interface and the established motor feedback interface, BiSS-C are used. Optionally, the analog real-time signal output can be provided with sin/cos signals 1 Vss. With ring diameters from 44 mm, an absolute resolution of up to 21 bits is achieved. The high repeat accuracy of 0.01° allows precision positioning at all times. A further special feature of the MSAC200 is its high installation tolerances. The distance between the sensor and the rule is ≤0.6 mm, and the axial tolerances are of the order of ±0.2 mm. This makes the construction of the complete system easier and allows use in dynamic applications.
The MSAC200 is suited for use in applications in which both high resolution and precision are accompanied by the need for flexible adaptation to the user’s design. These requirements apply to motor feedback, to handling and assembly automation, and to robotic systems.
