M20-7881342

Overview

The M20-7881342 is a double-row header connector from the Harwin M20 series, designed for board-to-board or cable applications. It features a 2.54 mm (0.100 inch) pitch with 26 positions arranged in a dual in-line configuration. The component utilizes gold-plated copper alloy contacts and a black polyamide 6T (PA6T) insulation housing rated UL94 V-0 for high-temperature stability. It employs a jackscrew fixing mechanism for secure attachment and supports through-hole termination.

Feature Summary

Dual in-line layout with jackscrew securing mechanism
High-temperature resistant PA6T insulation housing
Gold-plated copper alloy contact surfaces

Applications

Board-to-board interconnections
Cable-to-board connections
High-density electronic assemblies

Procurement Notes

Verify the specific variant against official datasheets to confirm the presence of the jackscrew fixing mechanism, as the M20 series includes both latching and screw-fix options. Ensure the ordering suffix matches the required contact plating and housing material specifications. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and compliance status.

Selection Notes

Select this component when a robust mechanical fix is required alongside high thermal performance. The PA6T housing allows operation up to 105°C, suitable for demanding environments. The jackscrew system provides superior retention compared to standard latching headers. Verify that the PCB footprint accommodates the specific row spacing and terminal dimensions defined in the official documentation.

Part Context

This connector belongs to the M20 series, which offers various configurations including single-row and double-row options. The series is characterized by its modular design and high reliability standards. The M20-7881342 specifically addresses needs for secure, high-density connections in industrial and commercial electronics where vibration resistance and thermal stability are critical.
