Key Features
- 36-position dual-row Tiger Eye terminal strip at 0.050" (1.27mm) pitch enables ultra-high-density board-to-board or board-to-cable connections
- Tiger Eye contact technology provides reliable wiping action and low insertion force for repeated mating cycles without contact damage
- Cost-effective design reduces per-connection cost in high-pin-count assemblies compared to premium fine-pitch connectors
- Tape-and-reel (TR) packaging supports automated pick-and-place assembly, minimizing handling and increasing throughput in volume PCB production
Applications
The TFC-118-02-LM-D-A-K-TR is designed for space-critical board-to-board and cable-to-board applications in compact electronics such as medical instruments, data communication modules, and portable test equipment. Its 0.050" (1.27mm) pitch and 36-position dual-row layout deliver 72 contacts in a minimal PCB footprint, supporting high-density signal routing in multi-layer PCB designs. Engineers specify this connector in RF front-end modules, FPGAs expansion boards, and miniaturized embedded systems where fine-pitch, cost-effective connectivity is a key design constraint.

Frequently Asked Questions
What pitch and position count does the TFC-118-02-LM-D-A-K-TR offer for high-density PCB designs?
The TFC-118-02-LM-D-A-K-TR features a 0.050" (1.27mm) pitch with 36 positions in a dual-row configuration, providing 72 total contacts in a very compact PCB footprint. This fine pitch is nearly half that of standard 2.54mm pitch connectors, allowing twice the contact density in the same board area, which is critical in miniaturized embedded computing, RF modules, and portable medical devices where PCB real estate is strictly limited.
What is the Tiger Eye contact technology in the TFC-118-02-LM-D-A-K-TR and how does it improve mating reliability?
Tiger Eye contact technology used in the TFC-118-02-LM-D-A-K-TR provides a wiping contact action during mating that removes surface oxidation from contact surfaces, ensuring low and stable contact resistance across all 36 positions and multiple mating cycles. This design maintains reliable signal integrity in applications requiring frequent connector mating, such as test fixtures and field-serviceable equipment, particularly in environments where oxide buildup on 0.050" pitch contacts could cause intermittent signal faults.
How does the 0.050" pitch of TFC-118-02-LM-D-A-K-TR compare to standard .100" connectors for a compact motor-control PCB?
At 0.050" (1.27mm) pitch, the TFC-118-02-LM-D-A-K-TR occupies approximately half the board length of a .100" (2.54mm) pitch connector carrying the same 36 positions. For a compact motor-control PCB where connector rows must fit within a 50mm board edge, switching from .100" to 0.050" pitch can reduce connector footprint length by up to 45mm, freeing space for power components or reducing overall PCB area and cost in volume production.
Is the TFC-118-02-LM-D-A-K-TR suitable for automated assembly and what packaging does it come in?
Yes, the TFC-118-02-LM-D-A-K-TR is supplied in tape-and-reel (TR) format, directly supporting automated pick-and-place machine loading in SMT production lines. Tape-and-reel packaging allows continuous feeding of the 36-position dual-row 0.050" pitch connector at high production speeds, reducing manual loading time and minimizing the risk of connector orientation errors compared to loose or bulk-packaged fine-pitch connectors.
