Key Features
- 27-position dual-row configuration on 2.54 mm pitch provides 54 circuits in a compact left-mount SMT form factor
- Shielded metal housing attenuates radiated EMI to protect adjacent high-speed signal traces on densely populated PCBs
- Left-mount horizontal orientation routes cable exit toward the PCB left edge, minimizing trace length and simplifying signal routing
Applications
The TSM-127-01-LM-SH-A is used in industrial control panels, embedded computing carrier boards, and backplane interconnect systems requiring a 54-circuit shielded SMT interface on 2.54 mm pitch. The left-mount orientation is preferred when the cable harness must exit parallel to the board surface toward the left side of the enclosure. The component is also common in high-density data acquisition systems and FPGA development boards that demand reliable shielded wire-to-board connections.

Frequently Asked Questions
What is the contact pitch and total circuit count of the TSM-127-01-LM-SH-A?
The TSM-127-01-LM-SH-A uses a 2.54 mm (0.100 inch) pitch with 27 positions across 2 rows, yielding 54 total circuits in a surface mount package suited to industrial and embedded board-to-wire applications.
How does the left-mount orientation of TSM-127-01-LM-SH-A affect PCB layout compared with top or right-mount variants?
The left-mount horizontal exit routes the cable harness parallel to and to the left of the connector body, reducing the need for a 90-degree cable bend and allowing the connector land pattern to sit up to 15 mm closer to adjacent components than a vertically exiting design.
Which shielding benefit does TSM-127-01-LM-SH-A provide for mixed-signal PCBs?
The integrated metal shield connects to board ground and surrounds all 54 signal contacts, reducing coupled noise by enclosing the contact field and preventing cross-talk from high-frequency switching converters or RF circuits operating within 50 mm of the connector.
Can TSM-127-01-LM-SH-A replace TSM-127-01-TL-SH-A in the same PCB design?
Both variants share the same 27-position dual-row 2.54 mm pitch and 54-circuit count, so the electrical interface is identical; the difference is the cable exit orientation (left-mount vs top-left), which may require rotating the connector land pattern by 90 degrees in the PCB layout.
