Description
The ID1101L incremental encoder kit consists of an
encoder and a linear scale (Fig. 1). The encoder is an
integrated circuit in a PCB housing. It provides incremental
A and B output signals in quadrature (Fig. 2). The linear
scale is a PCB with passive copper strips. Table 1 allows to
configure two possible orientations of encoder vs. scale.
Resolution, maximum speed and airgap
The resolution and the maximum speed of the encoder are
programmed ex-factory. The resolution depends on a filter
setting that limits the maximum speed of the encoder vs.
the scale. The resolution also depends on the maximum
distance between the encoder and the scale. Tables 2 and
3 allow the configuration of resolution and maximum speed
for a certain maximum air-gap.
Scales
Scales with different dimensions and period lengths are
available (Fig. 4) and are selected in Table 4. The scale
may be mounted on any substrate, using an edge for
accurate positioning in front of the encoder.

LookUp Table
For high-resolution high-precision applications, it is possible to linearize the encoder by means of a LookUp Table (LUT) that is
located inside the encoder. The LUT can be programmed in volatile or in non-volatile memory by means of the Programming
Tool, detailed info can be downloaded from www.posic.com. The ordering options for the LUT are given in Table 3.
