The GRACO 17L879 is a proximity switch designed for use in high-pressure lubrication systems. It is typically constructed from robust materials suitable for industrial environments and is intended to monitor and signal the position or movement of components within GRACO automatic lubrication equipment.

Key Features:

• Proximity Switch
• M11 x 1
• 5075 psi (350 bar)
• Fits CSP Divider Valve; available for all series progressive families
• High-pressure rating suitable for demanding environments
• Available in 115 VAC or 12-32 VDC versions
• Supports cycle rates up to 200 CPM
• Reliable operation for critical lubrication monitoring
• Easy to install and maintain

Applications:
Used in automatic lubrication systems for construction, fleets, transportation, industrial, mining, energy, and agriculture sectors to ensure proper lubrication and equipment protection.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety in high-pressure applications.
• Disconnect power and relieve system pressure before installation
• Remove plug or existing switch from the divider block piston port
• Screw the proximity switch into the port and torque to specification
• Connect signal wire to lube system controller if using M12 wireable cable
• Attach power wires to the power source
• Screw M12 connector into the proximity switch
• Verify LED status indicator if optional LED cables are used
• Regularly inspect for leaks or damage
• Ensure proper torque and secure connections
• Follow manufacturer’s pressure relief procedures
