TSM-105-04-SS-SH-A SAMTEC Connector (Other) In Stock
The SAMTEC TSM-105-04-SS-SH-A is a 5-position, 2.54 mm (0.100") pitch surface-mount terminal strip in a single-row horizontal configuration with stainless steel contacts. It provides a low-profile SMT footprint for board-to-board or board-to-wire interfacing in compact PCB designs. Well suited for consumer electronics, industrial I/O modules, and instrumentation requiring reliable 5-circuit SMT connectivity.

What are the key features of TSM-105-04-SS-SH-A?
- 5-position single-row layout on 2.54 mm (0.100 inch) pitch for compact SMT board connections
- Stainless steel (SS) contacts deliver enhanced corrosion resistance and durability over standard brass contacts
- Horizontal (SH-A) orientation keeps the mating interface parallel to the PCB surface for low-profile assemblies
- Surface-mount termination enables reflow soldering and eliminates through-hole drilling in dense PCB layouts
What is TSM-105-04-SS-SH-A used for?
The TSM-105-04-SS-SH-A is deployed in compact sensor modules, handheld instrumentation, and IoT edge devices where a 5-pin SMT connector must fit within a constrained PCB area at 2.54 mm pitch. Its horizontal mating direction suits enclosures where the mating plug enters from the board edge rather than perpendicular to the PCB surface. Stainless steel contacts make it a reliable choice for environments with moderate humidity or chemical exposure.

Frequently Asked Questions
What contact material does the TSM-105-04-SS-SH-A use, and why might an engineer choose it over a standard brass-contact terminal strip?
The TSM-105-04-SS-SH-A uses stainless steel (SS) contacts rather than the brass contacts found in standard TSM variants. Stainless steel provides a tensile strength approximately 2 to 3 times higher than brass and resists oxidation and mild chemical exposure, making it the preferred choice for connectors in outdoor sensors, laboratory instruments, or food-processing equipment where corrosion is a concern.
How does the horizontal (SH) mating orientation of the TSM-105-04-SS-SH-A affect PCB layout compared to a vertical terminal strip?
A horizontal orientation means the mating plug slides in parallel to the PCB surface, requiring clearance along the board edge rather than above the connector. This reduces the component height above the PCB to typically less than 5 mm, which is beneficial for slim enclosures or stacked-board assemblies where vertical clearance is limited to 8 mm or less.
Can the TSM-105-04-SS-SH-A be used as a direct alternative to a through-hole 5-pin 2.54 mm header in a redesigned board?
Yes, for a board being redesigned from scratch. The 5-position 2.54 mm pitch is electrically equivalent to a through-hole 5-pin header in terms of circuit count and spacing, but the surface-mount pads replace through-hole drilled vias. Designers must update the PCB land pattern from through-hole annular rings to SMT pads, and verify the mating cable connector is compatible with the TSM horizontal socket.
What current and voltage ratings apply to the TSM-105-04-SS-SH-A, and how do these constrain system design?
SAMTEC TSM series connectors are typically rated for 3 A per contact at 25°C ambient and up to 250 VAC working voltage. For the 5-position TSM-105-04-SS-SH-A, the total current capacity across all contacts is therefore up to 15 A with individual circuit loading, subject to derating at elevated temperatures above 70°C per the SAMTEC TSM datasheet thermal curves.
