Data
Technology's SM15
is a low cost, advanced industrial encoder. Manufactured with precision
surface mount technology, the SM15 utilizes high precision, spindle
grade ball bearings (shielded) providing a rugged encoder within its
design. The newest available within the SM15
encoder is the2631 series quad differential line driver designed for
digital data transmission over balanced lines. the 2631 meets all the
requirements of EIA standard RS-422 while retaining the low power
characteristics of CMOS. This enables the construction of serial and
terminal interfaces while maintaining minimal power consumption.
The SM15
utilizes a monolithic solar array with stop gap diffusion which provides
further noise immunity. The differential array tracks evenly under
temperature, voltage and light source variations.
