LTMM-113-02-S-D-SM-K

Headers, Male Pins Overview

The LTMM-113-02-S-D-SM-K is a surface mount header from the Flex Stack LTMM series, manufactured by Samtec Inc. It features a 2.00 mm (0.079 inch) pitch with 26 positions arranged in two rows. The connector utilizes phosphor bronze contacts with a gold plating thickness of 30.0 µin (0.76 µm) on the mating interface and tin plating on the tail. Constructed with liquid crystal polymer (LCP) insulation, it offers a shrouded four-wall design for board-to-board applications. The component supports pick-and-place assembly and operates within a temperature range of -55°C to 125°C.

Headers, Male Pins Feature Summary

• Shrouded four-wall housing design provides mechanical alignment and protection during board-to-board mating.
• Gold-plated contact surfaces ensure reliable electrical conductivity and corrosion resistance over repeated cycles.
• Integrated keying slots facilitate precise orientation and prevent misalignment during automated surface mount assembly.

Headers, Male Pins Applications

• High-density board-to-board interconnections in compact electronic modules
• Automated pick-and-place assembly processes requiring keyed connectors
• Surface mount applications demanding robust mechanical retention

Headers, Male Pins Procurement Notes

Verify that the specific part number includes the '-K' suffix, which denotes the presence of keying slots essential for alignment. Confirm the manufacturer is Samtec Inc. and check the datasheet for RoHS compliance status. Ensure the ordering quantity matches the standard tube packaging specifications provided by the supplier to avoid handling discrepancies.

Headers, Male Pins Selection Notes

Select this component when a surface mount header with integrated keying is required for a 2.00 mm pitch application. The dual-row configuration suits designs needing 26 connections in a compact footprint. Verify that the mating connector aligns with the specified contact length and shrouded geometry to ensure proper engagement and signal integrity.

Headers, Male Pins Part Context

This part belongs to the Flex Stack LTMM series, designed for high-reliability surface mount interconnects. The LTMM series is characterized by its low profile and robust construction using LCP materials. The specific model represents a mid-range pin count variant within the family, balancing density with ease of assembly for various industrial and commercial electronics.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.00 mm pitch, 26-position count, dual-row layout, and surface mount termination. Verify compatibility of the keying slot position and shrouded housing dimensions. Alternative parts from other manufacturers require validation of contact material specifications and operating temperature ranges.
