The M15 high resolution, Magnetic Incremental Encoder without Index offers reliable performance at an
economical price. This modular unit comes in a large range of resolutions with multiple po\
le commutations
and reference pulse options. This magnetic encoder can handle shaft sizes that range from .125” to\
.393”.
The patented EMI circuitry provides protection from high-frequency elect\
rical noise and background
magnetic fields. This low-profile design is perfect for stepper motor positioning and anti-stall feedback, DC
brush-type motor positioning, brushless DC, and servo motor control using the commutation options. The
M15 comes enclosed in a rugged IP40 package for protection from debris.

TerminologyDescription CPR (N): The Number of Cycles Per Revolution One Shaft Rotation: 360 mechanical degrees, N cycles One Electrical Degree ( oe): 1/360th of one cycle One Cycle (C): 360 electrical degrees ( oe). Each cycle can be decoded into 1 or 4 codes, referred to as X1 or X4 resolution mutiplication Symmetry: A measure of the relationship between (X) and (Y) in electrical degrees, nominally 180 oe Quadrature (Z): The phase lag or lead between channels A and B in electrical degrees, nominally 90 oe Index (CH I): The index output goes high once per revolution, coincident with the low states of channels A and B, nominally 1/4 of one cycle (90 oe) ELECTRICAL SPECIFICATION 910 East Orangefair Ln.
