The unit supports a current rating of 2 A and operates within a temperature range of -65°C to +150°C. It incorporates a jackscrew locking mechanism and meets UL 94 V-0 flammability standards.
Feature Summary
- Incorporates a jackscrew locking mechanism for secure board-to-board or cable connections.
- Features right-angle double-row geometry optimized for horizontal PCB termination.
- Constructed with halogen-free polyamide insulation and gold-plated phosphor bronze contacts.
Applications
- Board-to-board interconnects
- Cable-to-board assemblies
- Automotive electronics systems
Procurement Notes
Verify that the specific part number matches the required 12-position count and right-angle orientation. Confirm that the jackscrew locking style aligns with the mechanical design requirements. Ensure the operating environment falls within the specified -65°C to +150°C thermal limits before finalizing procurement decisions.
Selection Notes
Select this component when a low-profile, right-angle male header is required for dense circuit layouts. The 1.25 mm pitch allows for high pin counts in limited spaces. Consider the jackscrew feature if vibration resistance and positive locking are critical for the application stability.
Part Context
This connector belongs to the Harwin Gecko-SL family, which emphasizes high reliability and compact form factors. The series is engineered for demanding environments, offering robust mechanical performance alongside electrical stability. The specific model integrates standard industry interfaces with specialized locking features.
Replacement Considerations
No public confirmed substitute part numbers are available for this specific component variant.
FAQ
What type of locking mechanism does this connector use?
