Description

The flexible position determiners

The bearingless, magnetic MAGA absolute encoder systems are particularly flexible; thanks to the version with pulse wheel and scanning head they offer the highest levels of design freedom. They are suitable for direct attachment to shaft diameters up to approx. 1500 mm. Thanks to their narrow width of just 48 mm they are also particularly suitable for use in confined spaces. The pulse wheel is mounted directly onto the shaft where it also measures high speeds without any difficulty, for example on test stands. MAGA encoder systems are suitable for harsh operating conditions, for example, to determine the exact position of the shaft in automatic crane systems. The module variant with split pulse wheel offers a practical alternative for retrofitting and upgrading purposes or if there is no free shaft end available – with protection covers made of stainless steel or carbon fiber reinforced plastic (CFRP) on request.
