M80-4121001

Headers, Receptacles, Female Sockets Overview

The M80-4121001 is a board-to-board connector from the Harwin Datamate J-Tek series. It features a female plug configuration with straight solder terminals and locking capability. The unit utilizes gold-plated beryllium copper contacts for mating and tin/lead termination finishes. Rated at 120V, it employs a glass-filled polyphenylene sulfide insulator. The connector supports mixed contact arrangements and offers high durability against vibration and shock.

Headers, Receptacles, Female Sockets Feature Summary

• High-reliability four-finger beryllium copper contacts ensure connection integrity under harsh conditions.
• Locking mechanism provides secure attachment to prevent accidental disengagement.
• Durable construction withstands repeated mating cycles without performance degradation.

Headers, Receptacles, Female Sockets Applications

• Industrial control systems requiring robust interconnects
• Test and measurement equipment subject to vibration
• Automotive electronics in demanding environments

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count and row configuration required for your design, as the M80 series offers extensive variations. Confirm that the tin/lead termination finish aligns with your assembly process requirements. Ensure the locking feature is necessary for your application stability needs. Cross-reference the datasheet for precise dimensional tolerances before finalizing the component selection.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when high mechanical strength and resistance to shock are critical. The locking option adds security compared to non-locking variants. Consider the mixed contact capability if combining signal and power lines is needed. Evaluate the operating temperature range against your environmental specifications to ensure reliable performance throughout the product lifecycle.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Datamate J-Tek family, known for its compact size and high reliability. The M80 series is designed for applications where space is limited but performance must remain high. It serves as a direct replacement for older, less durable connectors in industrial and aerospace sectors requiring consistent electrical performance.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other Harwin M80 series female plugs with matching pitch and locking features. Verify contact arrangement and terminal type compatibility before substitution. Non-Harwin alternatives may lack the specific four-finger contact retention characteristics.
