Key Features
- 4-position single-row layout on 0.100 inch (2.54 mm) pitch for standard-density horizontal board connections
- Shielded (SH) housing provides integrated EMI protection without external shielding hardware
- Surface-mount horizontal orientation enabling low-profile PCB assembly with automated reflow compatibility
Applications
The TSM-104-01-H-SH-A is suited for wire-to-board and board-to-board signal connections in consumer electronics, industrial control panels, and embedded computing where a compact 4-pin horizontal interface with EMI shielding is required. The 0.100 inch pitch maintains compatibility with standard tooling and cable assemblies, simplifying integration into existing designs. Its shielded construction makes it especially useful near sensitive analog or RF circuitry where unshielded connectors would introduce noise coupling.

Frequently Asked Questions
What does the SH suffix mean on TSM-104-01-H-SH-A, and why does it matter for noise-sensitive circuits?
The SH suffix designates a shielded housing, which adds a conductive shell around the 4-position connector body. This shield reduces electromagnetic emissions and immunity problems by providing a low-impedance return path at high frequencies, making the connector suitable for use within 10 mm of RF or precision analog circuitry without requiring a separate shield can on the PCB.
What PCB footprint does the TSM-104-01-H-SH-A require, and does it suit automated assembly?
The TSM-104-01-H-SH-A uses surface-mount pads on 0.100 inch (2.54 mm) pitch in a single row, placing 4 pads across a total span of approximately 7.62 mm. The SMT termination is fully compatible with standard pick-and-place equipment and 260°C lead-free reflow profiles used in high-volume automated PCB assembly.
How does the TSM-104-01-H-SH-A compare with an unshielded 4-pin terminal strip for a motor-drive application?
In a motor-drive application generating switching noise above 100 kHz, the shielded TSM-104-01-H-SH-A significantly outperforms an unshielded strip by attenuating coupled interference on adjacent signal traces. The 4-pin count covers a typical enable, direction, PWM, and ground set, and the 0.100 inch pitch matches standard motor-control cabling, making it a direct drop-in upgrade over generic unshielded headers.
