What are the key features of TFM-122-01-LM-D-A-P-TR?
- Dual-row 22-position low-profile (LM) surface-mount terminal strip at 0.050" (1.27 mm) pitch minimizes board height in space-constrained assemblies
- Samtec Tiger Eye contact geometry provides wiping action that ensures reliable low-resistance mating in vibration-prone environments
- Tape-and-reel (TR) packaging optimizes compatibility with high-volume automated pick-and-place reflow assembly lines
What is TFM-122-01-LM-D-A-P-TR used for?
The TFM-122-01-LM-D-A-P-TR is well suited for board-to-board signal interconnects in embedded computing modules, FPGA development boards, and test and measurement equipment requiring high-density 1.27 mm pitch connections. The low-profile form factor is particularly valuable in stacked-board architectures where vertical clearance between boards is less than 5 mm. Tape-and-reel delivery supports automated assembly in high-volume production of communications and industrial control hardware.

Frequently Asked Questions
What pitch and position count does the TFM-122-01-LM-D-A-P-TR provide, and how many total contacts does that yield?
The TFM-122-01-LM-D-A-P-TR features a 0.050" (1.27 mm) pitch in a dual-row, 22-position configuration, yielding 44 total contacts. This density makes it practical for parallel data buses, FPGA I/O breakouts, and multi-channel signal routing within a compact surface-mount footprint.
How does the low-profile (LM) variant of the TFM-122 series benefit stacked-board designs?
The LM (low-profile) designation reduces the connector's body height compared to standard TFM variants, enabling board-to-board stack heights below 5 mm. This is critical in compact embedded modules where 1.27 mm pitch connectors must fit between tightly spaced PCBs without mechanical interference.
Which soldering processes are compatible with the TFM-122-01-LM-D-A-P-TR surface-mount package?
The TFM-122-01-LM-D-A-P-TR is designed for standard SMT reflow soldering with peak temperatures up to approximately 260 °C. The tape-and-reel format ensures accurate component orientation on the pick-and-place machine, and the gold-plated contacts are compatible with lead-free solder paste formulations used in RoHS-compliant production.
When is the TFM-122-01-LM-D-A-P-TR a practical alternative to a board-to-board socket pair in a test fixture?
A test fixture engineer may choose the TFM-122-01-LM-D-A-P-TR when a mating plug is already installed on a device-under-test and only a low-profile, 44-contact landing strip is needed on the fixture PCB. The Tiger Eye contact geometry provides reliable wiping action even after hundreds of mate-unmate cycles, reducing fixture maintenance intervals.
