Overview
The Harwin M20-7850746 is a 14-position, single-row PCB socket connector from the M20 series. It features a 2.54 mm pitch and is designed for board-to-board applications. The unit utilizes through-hole termination with nickel-plated tin contacts. Constructed with a nylon housing, it supports straight mounting orientation. The connector operates within a temperature range of -40°C to +105°C and carries RoHS compliance certification.
Feature Summary
- Dual-beam contact design enhances electrical connection stability and overall connector reliability.
- High-temperature liquid crystal polymer or nylon housing provides durability and thermal resistance.
- Compact form factor accommodates high-density PCB layouts and height restrictions.
Applications
- Embedded PC systems
- Motherboard interconnections
- Industrial monitoring equipment
- Consumer electronics assemblies
Procurement Notes
Verify the specific pin configuration and housing material against the official datasheet before procurement. Confirm that the nickel-plated tin finish meets the environmental requirements of the target application. Ensure the through-hole mounting style aligns with the PCB fabrication capabilities. Cross-reference the RoHS status with current regulatory standards for the destination market.
Selection Notes
Select this component when a single-row, 2.54 mm pitch socket is required for vertical board stacking. Consider the 14-position count and straight orientation for space-constrained designs. Evaluate the bronze contact material and plating for suitable conductivity in low-signal environments. Compare against dual-row alternatives if higher density per footprint is necessary.
Part Context
This part belongs to the Harwin M20 series, a standard industrial connector line known for robust performance. The series offers various row counts and positions, making it versatile for diverse electronic systems. It is widely recognized as a standard interface in embedded computing and large-scale electronic infrastructure projects.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with mating pins from other manufacturers using the 2.54 mm pitch specification.
