The Avtron AV56A is a modular, two piece incremental encoder (also known as a tachometer or rotary pulse generator). It provides a two phase, A Quad B frequency (pulse) output, with complements. The AV56A mounts on a 4.5" (NEMA 56C) Face.
Because the AV56A is modular, there are no bearings or couplings required. This, combined with the latest magnetoresistive (MR) sensor technology, allows the AV56A to provide superior mechanical performance and increased reliability.
An Avtron AV56A can be configured with one or two independent outputs. Each output has six signals: (A, B) 90° out of phase, with complements (A, B). A marker pulse with complement (Z, Z) is also provided.
