Overview
The M20-7890242 is a Harwin M20 series double-row female PCB socket assembly. It features a 2.54 mm pitch and utilizes horizontal surface mount termination. The connector supports 12 positions with nickel-plated phosphor bronze contacts. Designed for board-to-board applications, it operates within a temperature range of -40°C to +105°C.
Feature Summary
- Horizontal surface mount design for compact PCB integration
- Dual-row configuration providing high-density connectivity
- Integrated latch mechanism ensures secure mating engagement
Applications
- Board-to-board interconnections in industrial equipment
- High-density signal routing in consumer electronics
- Automotive control module interfaces
Procurement Notes
Verify the specific contact count and housing color against the official datasheet before ordering. Confirm that the horizontal orientation matches the target PCB layout requirements. Ensure compatibility with mating header assemblies from the same M20 series family to guarantee proper mechanical fit and electrical performance.
Selection Notes
Select this component when horizontal mounting space is limited compared to vertical alternatives. The integrated latch provides superior retention force over standard connectors. Verify that the 2.54 mm pitch aligns with existing board patterns. Consider the dual-row density benefits for complex signal routing needs.
Part Context
This part belongs to the Harwin M20 series, known for robust performance in demanding environments. The series offers various configurations including vertical and horizontal options. This specific model emphasizes secure connection through its locking feature while maintaining a low profile suitable for modern electronic assemblies.
Replacement Considerations
Direct substitutes must match the 2.54 mm pitch, double-row female configuration, and horizontal SMT termination. Verify identical latch mechanisms for equivalent retention forces. Cross-reference with other Harwin M20 variants ensuring compatible mating heights and contact materials.
