Magnetic absolute multiturn rotary encoder
max. ø 58 mm, IP67 | GEL 2352 LENORD + BAUER

The resilient encoder housing with a standard flange size of 58 mm is made of anodised aluminium and can be supplied alternatively in stainless steel. The double-bearing encoder shaft forms a robust mechanical unit with the metal code disc. The multiturn variant operates with a mechanical gear. A uniform temperature coefficient on all rotating components ensures the temperature behaviour of the absolute rotary encoder is stable over the long-term.
Sensing principle
The GEL 2352 is based on contactless magnetic scanning of a ferromagnetic steel code disc, the so-called contour disc. Magnetoresistive (MR) sensors scan three tracks, delivering corresponding sinusoidal signals. The phase position of the three sinusoidal signals is unambiguous within a
single turn. The phase position is evaluated on the Vernier principle, providing the absolute position with high resolution and accuracy.
