Overview
Phoenix Contact part number 1494992 is a spacer bolt designed for securing printed circuit boards to heat sinks. The component features an M2.5 thread with a total length of 25 mm and a face-to-face width of 5 mm. Constructed from galvanized steel, it provides vibration resistance through an external self-locking thread mechanism. The recommended tightening torque ranges from 0.8 Nm to 1 Nm using an SW5 tool.
Feature Summary
- Provides secure mechanical fixation between printed circuit boards and heat sinks
- Features external self-locking threads to ensure vibration resistance
- Constructed from galvanized steel for durability
Applications
- Mounting PCBs to heat sinks in industrial electronics
- Thermal management assembly in control cabinets
- Vibration-prone equipment mounting applications
Procurement Notes
Verify the specific thread size (M2.5) and length (25 mm) against design requirements. Confirm that the galvanized steel material and self-locking feature meet the environmental and mechanical standards of the target application. Ensure compatibility with the intended heat sink and PCB mounting hole specifications before procurement.
Selection Notes
Select this component when a rigid, vibration-resistant standoff is required between a PCB and a thermal dissipation surface. The M2.5 thread size dictates compatible fastener usage. Consider the 5 mm face-to-face dimension for spacing constraints. Verify that the operating environment does not exceed the corrosion protection limits of the galvanized finish.
Part Context
This spacer belongs to the UCS universal housing series by Phoenix Contact. It serves as a mechanical accessory rather than an electrical connector. The product is categorized under mounting hardware for electronic assemblies, specifically addressing thermal interface structural support.
