TMS-111-53-S-D

Headers, Male Pins Overview

The TMS-111-53-S-D is a .050" (1.27 mm) pitch micro header from the Samtec TMS series, designed for board-to-board interconnections. It features a dual-row configuration with 22 positions and male pin contacts. The connector utilizes a straight through-hole termination style and is constructed with a black liquid crystal polymer (LCP) insulator. Contacts are made of phosphor bronze and finished with gold over nickel plating to ensure reliable signal transmission. This component supports a wide operating temperature range from -55°C to +125°C.

Headers, Male Pins Feature Summary

• High-density .050" x .010" contact spacing allows for compact circuit board layouts.
• Gold over nickel plating provides durable corrosion resistance and low contact resistance.
• Liquid crystal polymer insulation offers high thermal stability and UL 94 V-0 flammability rating.

Headers, Male Pins Applications

• High-speed digital signal interconnects
• Memory module connections
• Industrial control system backplanes

Headers, Male Pins Procurement Notes

Verify that the specific order matches the standard lead time requirements, as manufacturing schedules may vary. Confirm that the receiving facility has appropriate handling procedures for surface-mount or through-hole components depending on the final assembly process. Ensure storage conditions maintain the integrity of the gold-plated contacts prior to installation.

Headers, Male Pins Selection Notes

Select this part when a dual-row, straight male header with .050" pitch is required. The gold plating is suitable for environments where corrosion resistance is critical. Verify that the PCB hole size accommodates the .010" diameter pins and that the mounting height fits within the mechanical envelope constraints of the enclosure design.

Headers, Male Pins Part Context

This component belongs to the TMS Micro Header Series, which is characterized by its fine .050" pitch and robust construction. The series is widely used in applications requiring high I/O density in a small footprint. The TMS-111-53-S-D specifically denotes a 22-position, dual-row variant with standard straight termination.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Samtec headers with identical .050" pitch and dual-row configuration, such as the MTMS series if variable post height is needed, provided the mating interface remains compatible. Ensure any replacement maintains the same current rating and temperature specifications.
