The GRACO 564402 is a proximity switch designed for use with MGO divider valves in automatic lubrication systems. It is constructed with robust materials for industrial environments and is intended to provide cycle feedback to monitors, controllers, or PLCs, enabling accurate monitoring and recording of lubrication cycles.

Key Features:

• Field Sensitive Magnetic (FSM) Proximity Switch
• 564402 (527-007-160), 5-Pin BH Mini
• Aluminum housing, stainless steel magnet housing, Buna-N O-ring
• Up to 10,000 psi (690 bar) for some models; for FSM switches, up to 8,000 psi (552 bar) is typical for MX, MXP, and MGO valve sections
• MGO Divider Valves
• Magnetically actuated, dry contact switch
• Provides cycle rate and cycle count feedback
• Designed for reliable operation in harsh environments
• Easy to install and maintain
• Suitable for both oil and grease applications (depending on specific model and configuration)

Applications:
Used in automatic lubrication systems to monitor and record the number of cycles and cycle rate of Series-Progressive (SP) divider valves, ensuring proper lubrication and system health.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure power is disconnected before installation or maintenance
• Install according to local electrical codes and regulations
• Use only qualified electricians for wiring
• Ground the equipment properly to prevent electric shock
• Refer to the equipment manual for specific installation instructions
• Regularly inspect for wear or damage
• Ensure O-rings and seals are intact
• Keep connections clean and secure
• Follow manufacturer’s recommended maintenance schedule
