Key Features
- 4-position dual-row SMT terminal strip at 0.100" (2.54 mm) pitch with shrouded housing that mechanically keys the mating cable connector to prevent mis-insertion
- Horizontal (A) mating orientation routes the mating cable parallel to the PCB surface, reducing connector height above the board for low-profile assemblies
- Surface-mount termination enables single-pass SMT reflow assembly without through-hole wave soldering, simplifying PCB manufacturing for compact designs
Applications
The TSM-104-03-SM-SH-A is suited for space-constrained cable-to-board interconnects on consumer electronics, IoT sensor nodes, and compact industrial control boards where only 4 signal or power connections are needed at 0.100" pitch. Its shrouded horizontal mating orientation keeps the mating cable lying flat against the PCB, making it practical for slim enclosures, panel-mounted modules, and embedded boards with restricted vertical clearance.

Frequently Asked Questions
What does the horizontal (A) mating orientation of the TSM-104-03-SM-SH-A mean for the height profile above the PCB?
The horizontal (A) suffix means the mating cable connector engages from the side, parallel to the PCB surface rather than perpendicular to it. This keeps the overall assembly height low, typically allowing the mated connector to fit within a few millimetres above the PCB — an important advantage for enclosures with tight vertical clearances in IoT devices, wearable modules, or thin industrial controllers at 0.100" pitch.
For a 4-position low-current signal connection, why choose the shrouded TSM-104-03-SM-SH-A over an un-shrouded 4-pin header?
The shrouded housing of the TSM-104-03-SM-SH-A keys the 4-position mating cable connector so it cannot be inserted backwards or shifted by one pin at 0.100" pitch. For signal interfaces such as UART, I2C, or SPI where a reverse connection could damage a microcontroller IO pin or create ground-signal swaps, the shroud provides a no-cost mistake-proofing benefit with no change to PCB footprint.
How does the surface-mount termination of the TSM-104-03-SM-SH-A simplify PCB assembly compared to through-hole alternatives?
The SMT termination of the TSM-104-03-SM-SH-A means the 4-position connector is placed and reflowed in the same SMT pass as resistors, capacitors, and ICs. There is no need for a separate through-hole insertion step, wave-solder pass, or selective-solder operation, which reduces manufacturing cost and line changeover time on boards that carry only SMT components otherwise.
What dual-row body feature makes the TSM-104-03-SM-SH-A different from a standard single-row 4-pin SMT header?
The dual-row body means the connector housing has two rows of contacts in a staggered or paired arrangement within the 0.100" (2.54 mm) pitch grid, providing a wider mechanical footprint for improved pull-out strength and rotational stability compared to a single-row strip. This added robustness is beneficial in applications like panel-mounted cables that may be plugged and unplugged frequently across the 4-contact interface.
