Linear Encoders
Operating and storage temperature range: 0 C to + 60 C
-25 C to + 85 C available on some models
Light source: gallium aluminum arsenide L.E.D. rated for 100,000 hrs.
Light detectors: photodiodes
Excitation voltage: + 5 Vdc standard
Zero reference: specify full, 1/2 cycle or 1/4 cycle wide
Output format: (2) count channels, 90 phase shifted, in quadrature
Vibration: 20 Hz to 2,000 Hz @ 5 G's
Shock: 50 G's for 11 µSec
Humidity: to 98% Rh (non-condensing)
Soda lime glass: coefficient of thermal expansion .0000045"/ F
Total encoder accuracy is the result of the sum of all errors, specified as,
1x accuracy error, quadrature error, and interpolator error (+/- 1/2 an
interpolated bit) these error sources sum at individual values statistically
less than theoretical maximums
