Overview
Phoenix Contact part number 1494983 is a spacer bolt designed for fixing printed circuit boards (PCBs) to heatsinks. The component features an M2.5 x 5 mm thread specification with a wrench size of AF5. Constructed from galvanized steel, it provides a silver-colored finish. The design ensures vibration resistance through a self-locking male thread mechanism.
Feature Summary
- Vibration-resistant mounting due to self-locking male thread
- Galvanized steel construction for corrosion protection
- Specifically engineered for PCB to heatsink fixation
Applications
- Fixing PCBs to heatsinks in universal housing assemblies
- Vibration-resistant mechanical mounting in electronic enclosures
- Thermal management system assembly within industrial control units
Procurement Notes
Verify the exact thread pitch and length requirements against the specific heatsink and PCB hole configurations before integration. Confirm that the galvanized surface finish meets the environmental exposure standards of the intended application. Ensure compatibility with the specified tightening torque range of 0.8 to 1 Nm to prevent thread damage during assembly.
Selection Notes
Select this component when a rigid, vibration-dampening connection between a PCB and a metal heatsink is required. The self-locking feature eliminates the need for additional locking nuts in standard vertical orientations. Consider the galvanized steel material if moderate corrosion resistance is sufficient for the operating environment.
Part Context
This spacer bolt belongs to the UCS series of mounting materials from Phoenix Contact, intended for use with their universal housing systems. It serves as a critical structural element in thermal management assemblies where electrical isolation or precise spacing between the board and cooling surface is necessary.
Replacement Considerations
No public confirmed substitute part numbers are available for this specific component. Direct replacement requires matching the M2.5 thread, 5 mm length, and self-locking characteristics exactly.
