What are the key features of TFC-124-02-FM-D-A-K?
- 48-position dual-row configuration at 0.050" (1.27 mm) pitch delivers high contact density in a compact PCB footprint
- Female mating (FM) contact interface mates securely with standard .050" pitch male headers for reliable signal connections
- Keying feature prevents mis-mating in multi-connector assemblies, reducing assembly errors in industrial and computing applications
What is TFC-124-02-FM-D-A-K used for?
The TFC-124-02-FM-D-A-K is used in high-density board-to-board signal routing for industrial controllers, embedded computing modules, and data acquisition systems requiring 48 positions at 0.050" pitch. Its keyed female mating ensures error-proof connector engagement during assembly and field service. The connector's compact dual-row format supports dense PCB layouts where signal count must be maximized within tight dimensional constraints.

Frequently Asked Questions
How many contact positions does the TFC-124-02-FM-D-A-K provide and how are they arranged?
The TFC-124-02-FM-D-A-K provides 48 total contact positions in a dual-row configuration with 24 positions per row at 0.050" (1.27 mm) pitch. This arrangement allows routing of up to 48 independent signals or power lines between mating PCBs within a connector footprint far smaller than equivalent single-row designs.
What advantages does the keying feature (K suffix) offer in high-density PCB assemblies?
The keying feature in the TFC-124-02-FM-D-A-K physically prevents incorrect connector orientation during mating. In assemblies with multiple adjacent 48-position connectors, such as multifunction I/O boards or backplane interconnects, keying eliminates the risk of swapped connectors that could cause signal misrouting, board damage, or system failures during initial bring-up or field replacement.
Which industries most commonly use the TFC-124-02-FM-D-A-K terminal strip?
Industrial automation, embedded computing, medical instrumentation, and telecom equipment manufacturers commonly use the TFC-124-02-FM-D-A-K. Applications include mezzanine card connectors, DSP module interconnects, and sensor interface boards where 48 signals must pass reliably at 0.050" pitch over thousands of mating cycles with Tiger Eye contact reliability.
How does the TFC-124-02-FM-D-A-K compare to wider-pitch alternatives for the same position count?
At 0.050" (1.27 mm) pitch, the TFC-124-02-FM-D-A-K occupies roughly half the PCB footprint of a comparable 0.100" pitch 48-position connector. This footprint reduction is critical in space-constrained designs such as compact industrial PLCs or small form-factor computing modules where board area is at a premium and signal density requirements are high.
