AV56A 1
DESCRIPTION
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 magneto resistive
(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.
Output resolution on the AV56A is determined by the sensor only. Unlike
older models, any PPRs can be mixed and matched. Selection of the
rotor is based only on the shaft mounting requirements (and not PPR).
