M20-7812045

Overview

The Harwin M20-7812045 is a specialized header component belonging to the M20 series, designed for high-density electronic interconnections. It features a 20-way configuration with a dual-in-line (DIL) arrangement across three distinct levels, providing a total of 60 contact positions. The connector utilizes a 2.54 mm pitch to ensure precise alignment and reliable signal transmission in compact PCB layouts. This socket assembly is engineered for wire wrap termination, offering a secure mechanical bond suitable for prototyping and fixed installations. Constructed with durable materials, it supports robust electrical performance within standard industrial operating temperature ranges.

Feature Summary

• Three-level DIL architecture maximizes connection density within a minimal footprint
• Wire wrap termination method ensures secure mechanical retention without soldering
• Dual-in-line configuration facilitates organized routing for multi-signal applications

Applications

• Prototype board development requiring rapid interconnection changes
• Test equipment fixtures needing frequent reconfiguration
• Industrial control modules with dense signal requirements

Procurement Notes

Verify the specific three-level pin configuration against schematic requirements before integration. Confirm that the wire wrap termination style matches the available tooling and manufacturing processes. Ensure the housing material compatibility aligns with the environmental conditions of the final assembly. Cross-reference the contact count to prevent mismatching with single or double-level alternatives.

Selection Notes

Select this component when space constraints necessitate a three-dimensional stacking of contacts rather than a flat planar layout. Consider the wire wrap termination requirement as a primary constraint, as it differs from standard solder or press-fit methods. Evaluate the need for high-density I/O in environments where physical access allows for manual or automated wire wrapping procedures.

Part Context

This part belongs to the broader M20 series of headers and wire housings manufactured by Harwin. While many series components utilize standard solder tail terminations, this specific model distinguishes itself through its unique three-level geometry and wire wrap interface. It serves as a niche solution within the portfolio, addressing specific design needs for modular and reconfigurable circuit architectures.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific three-level wire wrap variant. Standard two-row M20 sockets may serve as functional alternatives only if the three-level density and wire wrap termination are not critical constraints.
