Key Features
- 34-position dual-row low-profile SMT terminal strip at 0.050" (1.27 mm) pitch for space-constrained PCB designs
- Tiger Eye dual-beam contacts maintaining contact resistance below 20 milliohms over 500+ mating cycles
- Low-profile (LM) body variant reducing connector height above PCB for thin enclosure and stacked board designs
Applications
The TFC-117-02-LM-D-A-K is used in space-constrained board-to-board and board-to-module interconnect applications where a low-profile connector body height is required. Its 34-position dual-row 0.050" pitch footprint is suited for thin embedded computing modules, portable industrial handheld devices, and compact instrumentation requiring reliable signal connections. The Tiger Eye contact design ensures long mating cycle life for modules that are inserted and removed during maintenance or field reconfiguration.

Frequently Asked Questions
What does the LM suffix in TFC-117-02-LM-D-A-K indicate about the connector's physical profile?
The LM suffix designates a low-profile body height variant in the SAMTEC TFC series. This reduced connector height above the PCB is critical in applications such as stacked mezzanine boards, thin industrial handhelds, and compact embedded modules where vertical clearance is limited to a few millimeters between board layers.
How many signal positions does the TFC-117-02-LM-D-A-K provide, and what pitch supports those connections?
The TFC-117-02-LM-D-A-K provides 34 total positions arranged in dual rows with a 0.050" (1.27 mm) pitch. This configuration accommodates 34 simultaneous signal or power connections in a compact footprint, making it suitable for small embedded compute modules and I/O expansion boards in industrial and medical electronics.
For a portable device that is serviced frequently, what mating cycle reliability does the TFC-117-02-LM-D-A-K offer?
The Tiger Eye dual-beam contacts in the TFC-117-02-LM-D-A-K are rated for 500 or more mating cycles while maintaining contact resistance below 20 milliohms. This reliability is suitable for portable industrial devices and medical instrumentation modules that are regularly removed and reinserted during maintenance or calibration procedures.
How does the 34-position TFC-117-02-LM-D-A-K differ from the standard-profile TFC-117-02-F-D-A-K variant?
The TFC-117-02-LM-D-A-K uses a low-profile (LM) body that reduces connector height compared to the standard-height TFC-117-02-F-D-A-K. Both share the same 34-position count and 0.050" pitch dual-row footprint, but the LM variant is chosen when board stack clearance is less than the standard height allows, such as in tightly packaged enclosures with less than 5 mm board separation.
