When designing circuits and extension cables to use Optira encoders, be sure to account for
voltage loss over distance and tolerances from the nominal supply voltage so that at least the
minimum continuous voltage is available to the Optira encoder under all operating conditions.
3.2 Installation Considerations
The Optira encoder is a precision electronic instrument. It has been designed to function in a wide
range of applications and environments. To take full advantage of the Optira design, allow easy
access to the sensor for service and/or replacement.
For optimal performance and reliability:
•
DO follow standard ESD precautions while handling the sensor.
•
DO allow proper clearance for sensor head alignment.
•
DO follow setup and calibration instructions for the encoder system.
•
DO, where possible, install the scales in an inverted or vertical position to minimize
accumulation of dust.
•
DO NOT store sensors in an uncontrolled environment.
•
DO NOT electrically overstress the sensor (power supply ripple/noise).
•
DO NOT intentionally “hot swap” the sensor if the device is energized.
•
DO NOT use in high contamination applications (dust, oil, excessive humidity, or other
airborne contaminants).
