45240-200230

Headers, Male Pins Overview

The 3M 45240-200230 is a shrouded board mount header from the 452 Series, designed for surface mount technology applications. It features a dual-row configuration with 40 positions and a mating pitch of 0.050 inches (1.27 mm). The connector utilizes male pin contacts made of copper alloy, finished with gold plating on the mating interface and tin on the tail. Constructed with liquid crystal polymer insulation rated UL94 V-0, it supports a maximum current of 1 A at 125 VAC. The unit includes latch and eject mechanisms for secure connection and operates within a temperature range of -65°C to 125°C.

Headers, Male Pins Feature Summary

• Shrouded design with latch and eject hooks for secure board-to-cable connections
• Surface mount termination compatible with automated pick-and-place processes
• Gold-plated square contact terminals ensure reliable signal transmission
• Liquid crystal polymer insulation provides high thermal stability and flame resistance

Headers, Male Pins Applications

• Ribbon cable interconnections in industrial control systems
• Board-to-board or board-to-wire harness interfaces in consumer electronics
• Signal routing in telecommunications equipment requiring compact form factors
• Automotive electronic modules needing vibration-resistant connectors

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required row count and position quantity, as the 452 series offers various configurations. Confirm surface mount compatibility with your PCB fabrication capabilities. Ensure the operating temperature range meets your environmental requirements. Check for RoHS compliance documentation if mandated by your project standards. Validate that the latch mechanism aligns with your assembly workflow constraints.

Headers, Male Pins Selection Notes

Choose this component when a low-profile, dual-row header with positive locking is required for ribbon cables. The 0.050-inch pitch suits dense circuit layouts where space is limited. Consider the gold plating thickness for corrosion resistance needs. Evaluate the thermal rating against soldering profiles and ambient conditions. Compare against through-hole alternatives if mechanical stress relief is a primary concern.

Headers, Male Pins Part Context

This connector belongs to the 3M 452 Series, which focuses on maximizing design flexibility while minimizing PCB footprint. The series is engineered specifically for ribbon cable connections, offering both surface mount and through-hole options. The 45240 variant denotes a 40-position header, distinguishing it from other pin counts in the same family. It represents a standardized solution for high-density interconnects in modern electronic assemblies.

Headers, Male Pins Replacement Considerations

Direct substitutes include other 3M 452 series headers with identical 40-position and dual-row specifications. Verify that any alternative maintains the same 0.050-inch pitch and shrouded design. Cross-reference mounting style and latch type to ensure mechanical compatibility. Consult manufacturer cross-reference guides for exact pin-compatible replacements.
