• O-ring seal style, industrial-grade materials
• Up to 10,000 psi (690 bar)
• All series progressive families (MXP, MX, MXO Divider Valves)
• Field-sensitive magnetic detection for accurate cycle counting
• O-ring seal for enhanced durability and protection
• Suitable for high-pressure environments
• Provides cycle rates up to 200 CPM
• Reliable signal output to monitors, controllers, or PLCs
• Easy to maintain and replace

Applications:
Used in automated lubrication systems to monitor and control the cycle rate and number of cycles of progressive divider valves. Commonly applied in industrial, mining, and agricultural equipment requiring precise lubrication management.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure power is disconnected before installation
• Verify compatibility with the specific divider valve series (MXP, MX, MXO)
• Follow manufacturer wiring diagrams for 5-pin BH Mini connector
• Check O-ring seal integrity before installation
• Regularly inspect for wear and proper function as part of maintenance routines
