NOTES:
• The minimum recommended FASTRACK carrier length is 100 mm.
• The reference mark selector and limit actuator locations are correct for the readhead orientation shown.
• External magnetic fields greater than 6 mT, in the vicinity of the readhead, may cause false activation of
the limit and reference sensors.
