Key Features
- 30 positions on ultra-fine .050" (1.27 mm) pitch for high-density SMT board interconnection in compact designs
- Tiger Eye high-reliability contact geometry ensures positive retention and consistent mating force across mating cycles
- Split board lock mounting option provides mechanical strain relief and improved vibration resistance on the PCB
- Matte tin over nickel contact finish delivers reliable electrical contact and solderability in SMT reflow processes
Applications
The TFM-115-32-S-D-LC is ideal for space-constrained high-density PCB designs in portable instruments, medical devices, and aerospace electronics where 30 signals must be routed across a 1.27 mm pitch footprint. Its Tiger Eye contact design and split board lock deliver the mechanical reliability required in vibration-prone environments such as avionics racks and ruggedized industrial equipment. The compact 0.875 x 0.44 inch body keeps the connector footprint minimal while accommodating dual-row surface mount placement.

Frequently Asked Questions
What pitch and position count does the TFM-115-32-S-D-LC offer for high-density PCB connections?
The TFM-115-32-S-D-LC provides 30 positions on a fine .050" (1.27 mm) pitch in a surface mount vertical configuration. This combination allows designers to route 30 signals across a compact 0.875 inch body length, making it well-suited for dense multi-signal interconnects in portable and aerospace electronics.
What mechanical benefit does the split board lock feature add to the TFM-115-32-S-D-LC?
The split board lock feature provides mechanical retention pegs that press into PCB holes on either side of the connector, distributing mating and un-mating forces away from the solder joints. For a 30-position, 1.27 mm pitch connector, this dramatically improves resistance to vibration and repeated mating cycles without solder joint fatigue.
How does Tiger Eye contact technology in the TFM-115-32-S-D-LC enhance connector reliability?
Tiger Eye is SAMTEC's high-reliability contact geometry that provides a dual-beam wiping action during mating. In the TFM-115-32-S-D-LC 30-position connector, this design ensures low and consistent contact resistance, self-cleaning of oxidation on matte tin surfaces, and stable electrical performance across thousands of insertion cycles at the 1.27 mm pitch.
In which space-constrained applications is the TFM-115-32-S-D-LC most advantageous over a .100" pitch alternative?
At .050" (1.27 mm) pitch, the TFM-115-32-S-D-LC occupies roughly half the board length compared to a .100" (2.54 mm) pitch 30-position connector. This size advantage is critical in handheld medical instruments, avionics line-replaceable units (LRUs), and miniaturized data acquisition modules where PCB real estate is scarce and signal density must be maximized within a sub-1-inch footprint.
