Sealing Air Pressure Kit
A sealing air pressure kit (catalog number MPF-7-AIR-PURGE) is available for field installation
on an M23 feedback connector. Positive air pressure supplied through this kit provides an
additional level of protection for the motor against the ingress of foreign substances and
moisture.
The kit replaces the M23 feedback connector cap, provides a replacement O-ring, and includes
installation instructions.
When designing a motion system, consider these installation guidelines when installing a sealing
air pressure kit:
•
Use plastic air tubing that is 4 mm (5/32 in.) OD Teflon FEP.
•
Do not exceed 0.1 bar (1.45 psi) air pressure.
•
The air fitting extends 26 mm (1.0 in.) from the M23 connector when installed.
Air Kit Installation on the M23 Feedback Connector
ATTENTION: Excessive air pressure and improper filtering of air can result in damage to the motor.
Air supplied to the motor must be clean, dry, and of instrument quality. Maximum air pressure is 0.1 bar (1.45 psi).
