tical Encoder
Packaged in a glass filled polycarbonate housing with 1/8" stain less steel shaft and
precision bearings, the EX11 provides superior performance at a lower cost.
The EX11 Series was developed to provide a hig h precision, low cost en closed shaft
encoder for light duty applications. The EX11 offers benefits of the O pto-ASIC design
with 1024 line counts in a 1.1 inch diameter size.
The EX11 Series is capable of oper ating over a tem perature range of 0°C to +70°C
without degradation of signals.
