1. Available as described in Feedback Types.
2. Stator voltage and pole options allow for catalog rated performance at varying amplifier bus voltages and pole configuration requirements.
3. 0.75 lead not available in 12" or 18" stroke.
4. The dynamic load rating of zero backlash, preloaded screws is 63% of the dynamic load rating of standard non-preloaded screws. The calculated travel life of a preloaded screw will be 25% of the calculated travel life of the same size and lead of a non-preloaded screw for the same application. Preloaded follower is not available with absolute internal feedback.
5. Not available with splined main rod option.
6. This housing option would typically be accompanied by the choice of the electroless nickel connectors if a connectorized unit were selected. This choice may also indicate the need for special material main rods or mounting.
7. Linear feedback is not available in the GSM20 and not available in the GSM30 14" and 18".
8. Not available with absolute feedback.
9. Requires Anti-Rotate Option
10. Not available with extended tie rod mounting option.
11. Not available on GSM20.
12. Not compatible with Kinetix 300 drives.
13. Consult Exlar application engineering for available speeds at DC bus voltages.
14. A second anti-rotate arm is used on GSM20, 30 and 40 for 10 inch and longer stroke.
15. N/A with holding brake unless application details are discussed with Exlar Applications Engineer.
