Mounting Considerations The following items must be considered when mounting the High
Resolution Magnetic Feedback option.
– Shield the sensor from direct exposure to oil and water. Over a period
of time the sensor may be damaged by some coolant mixtures. The gear
assembly is steel and may rust if exposed to sprayed water.
– Protect the gear and sensor from metal chips. The clearance between
the sensor face and the gear is very small, so any metal chips caught on
the gear will damage the sensor face.
– Protect the sensor from iron dust or chips. The sensor contains a
permanent magnet – iron dust and chips will easily adhere to it and
interfere with proper system operation.
– To assure ease of alignment, mount the gear and sensor in an easily
accessible location.
