Why Choose Celera Motion's Zettlex IncOder over Traditional Slab Resolvers

Slab resolvers are used extensively in motion control applications for the feedback of rotational position and velocity. The term ‘slab resolver’ refers to a resolver with a bigger diameter proportionate to its axial height. Generally, slab resolvers also have a big bore in order to contain through shafts, electrical cables, hydraulic pipes etc.

Slab resolvers are known to have a long track record for offering consistent position and velocity feedback and also commutation without being limited by the environmental restrictions imposed by various other sensing methods. The shock and vibration levels encountered in aerospace, military or heavy industrial equipment are normally within the operating envelope for several of the slab resolvers.

Celera Motion's Zettlex Technology vs Slab Resolvers

Along with RVITs, RVDTs, synchros and Inductosyns™, slab resolvers are known to be a ‘traditional’ form of inductive position sensor, and have a number of disadvantages when compared with their recent equivalents. Celera Motion's Zettlex IncOders are based on the same primary physics as slab resolvers and thus offer the same high levels of strength.

Using laminar constructions with printed circuits as opposed to standard large spools of wire, IncOders are more compact, less expensive and lighter, providing a more favorable solution for engineers with considerably greater design and integration flexibility. Celera Motion's Zettlex IncOders’ low height, huge inner diameter and tolerance to misalignment make installation stress-free in applications such as pan and tilt pedestals, rotary joints and gimbals mounts.
