What are the key features of TSM-127-02-TL-SH-A?
- 54-position dual-row 0.100 inch (2.54 mm) pitch SMT terminal strip for high-density signal routing in compact PCB layouts
- Horizontal (TL) through-hole tail orientation compatible with wave and reflow soldering for reliable mechanical and electrical attachment
- SH shrouded housing provides mechanical keying and contact protection, reducing mismating risk during cable assembly
What is TSM-127-02-TL-SH-A used for?
The TSM-127-02-TL-SH-A is used in embedded systems, test fixtures, and industrial control boards where a large number of signals (up to 54) must be routed through a single 0.100 inch pitch connector in a compact footprint. The dual-row configuration and shrouded housing make it suitable for backplane interfaces, daughter-card connectors, and internal cable harness terminations in equipment where mating reliability is critical. Its SMT footprint supports automated assembly and reduces the total number of connector components needed on a densely populated board.

Frequently Asked Questions
How many positions does the TSM-127-02-TL-SH-A provide, and what is its contact pitch?
The TSM-127-02-TL-SH-A is a 54-position dual-row terminal strip with 0.100 inch (2.54 mm) centerline pitch, providing 27 positions per row. The 2.54 mm pitch is the standard industry pitch for through-hole and SMT headers, ensuring broad compatibility with mating connectors and IDC cable assemblies rated for signals up to 2 A per contact.
What does the 'SH' designation in TSM-127-02-TL-SH-A indicate, and why is shrouding important for industrial designs?
The 'SH' designation indicates a shrouded housing that surrounds all 54 pins with a plastic wall, providing mechanical keying and preventing mismating during field cable installation. In industrial environments where technicians connect and disconnect harnesses hundreds of times per year, shrouded connectors reduce mismating events by more than 80% compared to unshrouded strips, protecting circuits operating at 5 V or higher signal levels.
Can the TSM-127-02-TL-SH-A be used as a daughter-card interface, and what mating connectors are compatible?
Yes, the TSM-127-02-TL-SH-A is well suited as a daughter-card or mezzanine interface in systems requiring 54 or fewer signal connections at 0.100 inch pitch. SAMTEC's SSW and SSQ series sockets with 0.100 inch pitch are direct mating options. The dual-row horizontal tail layout also mates with standard 2.54 mm IDC ribbon cable assemblies, supporting data rates up to 100 MHz on short board-to-board links of 10 cm or less.
Is the TSM-127-02-TL-SH-A RoHS compliant, and what assembly process does it support?
The TSM-127-02-TL-SH-A is manufactured to RoHS compliance standards, using Pb-free contact finishes. Its surface-mount (SMT) tail design supports reflow soldering at standard peak temperatures up to 260°C per IPC-J-STD-020 classification. The through-hole tail variant (TL) also permits wave soldering, giving assembly engineers flexibility across mixed-technology PCBs with both SMT and through-hole components on a single 2-layer or multilayer board.
