What are the key features of TFC-112-02-FM-D-A?
- 24-position dual-row male terminal strip on 0.050 inch (1.27 mm) pitch, offering 2 more positions than the TFC-111 for designs requiring an additional signal pair
- Tiger Eye friction-mate contact design delivers repeatable low-resistance mating without latching hardware, enabling tool-free insertion and removal
- Vertical through-hole (FM) mounting provides strong mechanical retention in PCB assemblies subject to vibration or repeated connector mate/unmate cycles
- Cost-effective TFC series reduces connector BOM cost compared to premium SAMTEC HLE or MTSW series on medium-density 1.27 mm pitch interfaces
What is TFC-112-02-FM-D-A used for?
The TFC-112-02-FM-D-A is used in embedded computing daughter cards, sensor breakout boards, and JTAG/debug interface connectors where a 24-position 1.27 mm pitch dual-row male header is needed with standard through-hole soldering. Its 24-position count naturally fits 20-bit parallel buses with 4 power and ground positions, making it well-suited for microcontroller peripheral expansion boards. The Tiger Eye contact design simplifies bench prototyping and field-replaceable module connectors in laboratory and light industrial equipment.

Frequently Asked Questions
How many positions does the TFC-112-02-FM-D-A have, and how does this compare to adjacent SAMTEC TFC variants?
The TFC-112-02-FM-D-A has 24 positions arranged in 2 rows of 12 on a 1.27 mm (0.050 inch) pitch, placing it between the 22-position TFC-111 and the 26-position TFC-113. The additional 2 positions over the TFC-111 accommodate an extra signal pair or a dedicated power-ground pair without increasing the connector footprint significantly.
What does the -FM suffix designate in the TFC-112-02-FM-D-A part number?
The -FM suffix indicates a vertical friction-mate through-hole mounting style. The connector pins pass through plated holes in the PCB and are wave-soldered or hand-soldered from the bottom side. This through-hole mounting provides mechanical pull-out strength typically greater than 10 N per row, which is higher than surface-mount alternatives, making it suitable for connectors that are plugged and unplugged in the field.
For a 20-bit parallel bus design, why is the TFC-112-02-FM-D-A a practical connector choice?
A 20-bit data bus requires 20 signal pins plus at least 2 power and 2 ground pins, totaling 24 connections—exactly matching the TFC-112-02-FM-D-A's 24-position count. The 1.27 mm pitch keeps the connector body compact, fitting within a 15 mm wide PCB card edge zone when arranged in 2 rows of 12. This eliminates the need for a larger 26-position or 30-position connector that would consume excess board area.
How does the TFC-112-02-FM-D-A perform in prototyping scenarios where frequent connector insertion and removal is expected?
The Tiger Eye friction-mate contact design in the TFC-112-02-FM-D-A allows insertion and extraction by hand in under 10 seconds without additional tools. For prototyping bench setups where boards are swapped 10 to 20 times during development, the connector maintains acceptable contact resistance throughout. For production fixtures requiring more than 50 insertion cycles, upgrading to a SAMTEC HLE or TFM series with higher cycle ratings is recommended.
