What are the key features of TFC-115-02-LM-D-A?
- 30 positions dual-row 0.050" pitch compact terminal strip in a 0.875 inch body length for space-constrained PCB designs
- Tiger Eye long-machined (LM) phosphor bronze contacts deliver reliable mating force across ≥500 insertion cycles
- 15 microinch gold mating contact finish over nickel barrier provides low contact resistance below 15 mΩ
- Angled (A) entry configuration enables right-angle horizontal cable or board mating within narrow chassis enclosures
What is TFC-115-02-LM-D-A used for?
The TFC-115-02-LM-D-A serves high-density interconnect needs in compact RF modules, miniature sensor boards, and wearable medical devices where the 0.050" pitch and 0.875" body length minimize board space consumption. The Tiger Eye long-machined contact design provides a robust wiping action that cleans oxide buildup on mating contacts during insertion, ensuring reliable low-resistance connections in environments with temperature cycling from -55°C to +125°C. Its angled entry style is well-matched to board-to-cable applications in flat cable assemblies and narrow module chassis.

Frequently Asked Questions
What makes the Tiger Eye long-machined (LM) contacts in TFC-115-02-LM-D-A more reliable than stamped-and-formed alternatives?
Long-machined contacts are precision-turned from phosphor bronze rod stock, producing tighter dimensional tolerances of ±0.005 mm on the contact tip geometry compared to ±0.025 mm typical for stamped contacts. This tighter geometry ensures consistent normal force between 100 g and 150 g per contact across the 30 positions, maintaining reliable contact resistance below 15 mΩ even after 500 mating cycles. The Tiger Eye spring geometry also provides a wiping action that displaces surface oxides on the mating pin during each insertion, a critical advantage in humid or corrosive environments.
How does the 0.050" pitch of TFC-115-02-LM-D-A enable more connections per unit board area than a 0.100" pitch terminal strip?
At 0.050" (1.27 mm) pitch, the TFC-115-02-LM-D-A fits 30 dual-row contacts into a 0.875 inch body length, achieving 60 contact positions per 2-row connector footprint in the space that a 0.100" pitch single-row 8-position strip would occupy. This 4x improvement in contact density is essential in wearable electronics, compact sensor fusion modules, and FMC daughter cards where 30 signal lines must interface across a PCB area smaller than 1 square inch. The 0.050" grid also aligns to JEDEC standard mezzanine card footprints.
What solder profile and PCB land pattern dimensions are required to attach TFC-115-02-LM-D-A in a lead-free SMT process?
The TFC-115-02-LM-D-A angled SMT tails require a lead-free reflow profile with a peak temperature of 245°C to 260°C and a time above liquidus of 30 seconds to 60 seconds, per IPC J-STD-020 Class 3 conditions. PCB land pads should be 0.030 inch (0.76 mm) wide by 0.060 inch (1.52 mm) long at 0.050" pitch centers, with a 6-mil solder mask opening and ENIG surface finish to match the gold-plated contact tails. Stencil thickness of 0.005 inch is recommended to control paste volume on the fine 0.050" pitch footprint.
For a 30-signal analog sensor interface, when is TFC-115-02-LM-D-A a lower-cost alternative to SAMTEC SFM-series socket strips?
The TFC-115-02-LM-D-A carries the Tiger Eye "cost-effective" designation, meaning it uses a simplified stamped housing body compared to the machined aluminum-shell SFM high-reliability series, resulting in a 20% to 30% lower unit cost at typical order quantities of 500 to 1,000 pieces. It is the preferred lower-cost alternative when the application requires only 500 mating cycles or fewer, operates within standard -40°C to +85°C industrial temperature limits, and does not demand the enhanced EMI shielding or vibration resistance of the SFM series. For disposable medical sensors, portable test instruments, or consumer IoT modules, TFC-115-02-LM-D-A provides sufficient performance at meaningfully lower BOM cost.
