ORDERING INFORMATION
NOTES:
1. Channel A leads Channel B for clockwise shaft rotation when viewed from
housing front. Conversely, Channel B leads Channel A for Counterclockwise
shaft rotation.
2. The number of lines on the optical disc determines the Pulses Per Revolution
(PPR).
3. Duty Cycle is the relationship of output “High” time, “a”, to output “Low”
time, “b”, and is expressed as a High/Low percentage ratio, ie....% High time
= a/(a+b) x 100; % Low time = b/(a+b) x 100.
4. Quadrature Phase “c” is specified as the lead or lag between Channel A & B
in electrical degrees. Nominally 90° (1/4 cycle).
LENGTH SENSOR MOUNTING CONSIDERATION
1. Length Sensors should be mounted so measuring wheel(s) contact ribbon,
strip or web as it passes over a roller. As an alternative, wheel(s) can be driven
by roller surface next to material being measured.
2. Note: The weight at the Length Sensor unit provides sufficient traction for
accurate operation when mounted, with arm angle from horizonal not
exceeding ±30
o
.
3. Tension on signal cable can cause wheel(s) to lift. Make sure cable is clamped
to machine frame near the unit and allow slack.
