M20-7852142

Overview

The M20-7852142 is a vertical pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a 2.54 mm (0.100 inch) pitch and consists of two rows with a total of 42 positions. The connector utilizes square male pins with tin plating on both the mating and tail sections. Constructed with a black polyamide (PA6T) insulation housing, it supports a rated current of 3A per contact and operates within a temperature range of -40°C to 105°C. The unit employs a push-pull locking mechanism and is UL94 V-0 flammability rated.

Feature Summary

• Features a robust push-pull locking system for secure board-to-board or cable connections.
• Utilizes high-temperature resistant PA6T insulation material for enhanced thermal stability.
• Designed with square male contacts to ensure reliable mating engagement.
• Supports customizable cuttable configurations for flexible circuit board layouts.

Applications

• Industrial control systems requiring secure interconnects
• Automotive electronics modules
• Telecommunications equipment backplanes
• General-purpose printed circuit board assemblies

Procurement Notes

Verify the specific part number against official Harwin documentation to confirm current availability status and lead times. Ensure that the required stacking heights and mating partner connectors are compatible with the M20 series specifications before finalizing procurement orders.

Selection Notes

Select this component when a high-density, vertically oriented header with a 2.54 mm pitch is required. Consider the 42-position count and dual-row layout for space-constrained designs. Verify that the through-hole termination method aligns with the manufacturing process and that the 3A current rating meets the electrical requirements of the application.
