Exposed optical incremental linear encoder
AT211A/ AT211B MITUTOYO

FEATURES
* High-resolution, high-accuracy sealed type
linear scales. Ideal for feedback control in
positioning machines in semiconductor
manufacturing systems, CNC machine
tools, etc.
* Two types of models are available: the
AT211A, the multiple-point installation
type designed for improved resistance
against vibration and shock, and the
AT211B, which attaches to a machine at
both ends. The AT211B is compatible with
the AT111 slim type in size.
