The Graco 117514 Spacer Circuit Board ensures proper spacing and electrical isolation for reliable sprayer operation:
The Graco 117514 Spacer Circuit Board is a precision-engineered component designed to maintain optimal spacing, ensure electrical isolation, and protect sensitive electronics in airless sprayer systems.
| Feature | Description |
|---|---|
| Dimensions | 1.2 in × 1.2 in × 1.2 in (±0.02 mm tolerance) |
| Material | Glass-filled epoxy (FR-4), corrosion-resistant, UL 94 V-0 flame rated |
| Function | Maintains planar spacing and electrical isolation between boards |
| Thermal & Vibration Tolerance | Tested from –40 °C to 85 °C; vibration endurance 20–2000 Hz |
| Fluid Compatibility | Resistant to solvent-rich high-viscosity coatings |
The spacer features CNC-precision mounting holes, color-coded fiducials for correct orientation, and ENIG surface plating to maintain low contact resistance. It ensures stable signal integrity and optimal pump performance in high-pressure systems.
Maintains consistent dielectric separation and reduces pump wear. Routine visual inspection is recommended every 500 hours of continuous use. Replacement aligns with pump seal maintenance intervals to maximize system longevity.
