    DESCRIPTION
    The M15 high-resolution, Magnetic Incremental Encoder with 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, electrical 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 debr\
    is.

    							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)
