The GRACO 564403 is a field sensitive magnetic proximity switch designed for use with MXP, MX, and MXO series-progressive divider valves. It is constructed with an aluminum housing, stainless steel magnet housing, and Buna-N O-ring seals. This switch is intended to provide a signal to a monitor, controller, or PLC to indicate the number of cycles and cycle rate of the divider valve, enabling monitoring and recording of lubrication cycles.

Applications:
Used in centralized lubrication systems to monitor and record the cycle status of series-progressive divider valves, ensuring proper lubrication and system performance in industrial environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure correct voltage (24 VDC or 115 VAC) is supplied as per switch version
• Verify compatibility with the specific divider valve model (MXP, MX, or MXO)
• Use appropriate electrical connectors as required by the application
• Check for proper sealing and secure mounting to prevent leaks and ensure accurate sensing
• Regularly inspect for wear and proper function to maintain system reliability
