Basic information to the CNS50

The CNS50 was an incremental motorfeedback series, for servo motors, with commutation signals.

In the attachment, there are the data sheets and the mounting instruction:

The CNS50 encoder series is replaced by the CFS50 encoder series.

But unfortunately there are 2 problems:

not all mounting variants are available
1. the 7 mm plug in shaft --> only some special versions --> search for "CFS50 with plug in shaft"
2. The connector version --> there is only the cable version available
the CFS50 is also in the phase out phase and there is no replacement series for the CFS50 available

Here a table with the type code of the old CNS50 and the newer CFS50:

A = plug in with rubber
7mm plug in shaft with rubber stator coupling

F = taper with metal

1:3 taper shaft with metal spring stator coupling

E = taper with rubber

1:3 taper shaft with rubber stator coupling

G = taper with resolver

1:3 taper shaft with with resolver stator coupling
