What are the key features of TFC-136-02-LM-D-A?
- 72-position dual-row terminal strip on 0.050 inch (1.27 mm) pitch enables very high pin-count signal routing in a minimal PCB footprint
- Tiger Eye contact geometry ensures consistent normal force and reliable low-resistance mating across multiple insertion cycles
- Right-angle low-profile (LM) mounting style keeps the mating interface parallel to the board surface for edge-accessible connections in height-constrained enclosures
- Cost-effective TFC series construction reduces BOM cost on high pin-count interconnects without sacrificing basic signal integrity
What is TFC-136-02-LM-D-A used for?
The TFC-136-02-LM-D-A is used in FPGA daughter cards, industrial multi-channel I/O expansion boards, and backplane interconnect systems where 72 signal positions must be routed at a 1.27 mm pitch in a right-angle low-profile layout. Its dual-row configuration allows designers to maximize signal density along the card edge while maintaining easy cable or mating connector access. The friction-mate Tiger Eye contacts support rapid prototyping rework and field maintenance without additional tooling.

Frequently Asked Questions
What pitch and position count define the TFC-136-02-LM-D-A, and how does this compare to lower-count TFC variants?
The TFC-136-02-LM-D-A provides 72 positions on a 0.050 inch (1.27 mm) dual-row pitch, making it the higher-density option in the TFC series compared to 22-position (TFC-111) or 62-position (TFC-131) variants. This 72-position count supports parallel buses, FPGA GPIO banks, and multi-channel ADC interfaces where a single connector must carry more than 60 signal lines.
What does the -LM suffix indicate about the TFC-136-02-LM-D-A's mounting configuration?
The -LM suffix designates a right-angle low-profile mount, meaning the connector body exits parallel to the PCB surface at a reduced standing height typically under 5 mm. This is advantageous in stacked board designs or shallow enclosures where standard right-angle connectors would exceed the available vertical clearance. It allows the mating cable or receptacle to approach from the board edge with minimal vertical obstruction.
In what types of multi-channel industrial or FPGA systems is the TFC-136-02-LM-D-A most commonly used?
This 72-position terminal strip is commonly used in FPGA mezzanine card interfaces, industrial data acquisition boards with 64 or more channels, high-channel-count motor drive I/O expansion modules, and prototyping platforms for parallel memory bus evaluation. Designs that route 36 signals per row at 1.27 mm pitch, such as a 32-bit data bus plus control signals, fit naturally within the TFC-136's 72-position dual-row layout.
How does the friction-mate design of the TFC-136-02-LM-D-A affect field serviceability and rework?
The Tiger Eye friction-mate contacts allow the mating connector or pin strip to be inserted and removed by hand without latching mechanisms or ejector tools. This reduces rework time to under 30 seconds per connector in field maintenance scenarios. However, the friction-mate design is optimized for fewer than 30 insertion cycles; for applications requiring frequent board swaps exceeding 50 cycles, a latched alternative should be considered.
