HTMS-124-01-S-S-RA

Headers, Male Pins Overview

The HTMS-124-01-S-S-RA is a rectangular board-to-board header connector manufactured by Samtec Inc. It features 24 contacts arranged in a single row with a 0.050-inch (1.27mm) pitch. The connector utilizes male pins designed for right-angle through-hole mounting, facilitating side-entry PCB integration. Contact materials consist of phosphor bronze with gold plating on the mating surfaces and tin plating on the tail sections to ensure reliable soldering. The housing is constructed from black liquid crystal polymer (LCP), rated UL94 V-0 for flammability. It operates within a temperature range of -55°C to 125°C and supports a current rating of 5A per contact.

Headers, Male Pins Feature Summary

• Right-angle through-hole mounting design enables compact side-entry board-to-board connections.
• Gold-plated mating contacts provide durable conductivity and corrosion resistance.
• High-temperature LCP insulation ensures stability across wide operational ranges.

Headers, Male Pins Applications

• Board-to-board interconnections in dense electronic assemblies
• Side-entry PCB mounting configurations requiring right-angle headers
• Industrial control modules operating within extended temperature ranges

Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required contact plating configuration, as variations exist between gold and tin finishes. Confirm the pin count corresponds exactly to the '24' designation in the model number to avoid mismatched layouts. Ensure procurement documentation references the correct RoHS compliance status and material specifications for regulatory adherence.

Headers, Male Pins Selection Notes

Select this component when a single-row, right-angle header with a 1.27mm pitch is required for through-hole assembly. Consider the 5A current rating and -55°C to 125°C operating range against system thermal and electrical demands. Verify that the unshrouded design aligns with mating connector compatibility and spatial constraints within the enclosure layout.

Headers, Male Pins Part Context

This part belongs to the HTMS series of micro headers from Samtec Inc., characterized by low-profile designs suitable for high-density applications. The series offers various pitch options and mounting styles, with the RA suffix indicating right-angle orientation. These connectors are engineered for reliable signal transmission in space-constrained environments.

Headers, Male Pins Replacement Considerations

Direct substitutes include HTMS-124-01-G-S-RA, which shares identical mechanical dimensions but differs in contact plating specifications. Ensure any replacement maintains the same 24-position count, 1.27mm pitch, and right-angle through-hole mounting characteristics to preserve board layout integrity.
