Key Features
- 74-position dual-row design at 0.050" (1.27 mm) pitch maximizes signal density for complex multi-channel board interconnections
- Tiger Eye female contacts provide consistent low-resistance mating across hundreds of insertion and extraction cycles
- Integrated keying feature prevents misoriented mating in assemblies using multiple identical connectors on a single PCB
Applications
The TFC-137-02-F-D-A-K suits high-signal-count board-to-board interconnect applications in industrial automation, data acquisition, and embedded computing platforms. With 74 positions at 0.050" pitch, it handles complex multi-channel signal buses between mezzanine and carrier boards efficiently. The keying option makes it reliable in field-service scenarios where boards are regularly swapped or reconfigured by technicians.

Frequently Asked Questions
What is the total position count and pitch of the TFC-137-02-F-D-A-K connector?
The TFC-137-02-F-D-A-K provides 74 total contact positions in a dual-row arrangement with 37 positions per row at 0.050" (1.27 mm) pitch. This high position count combined with fine pitch enables routing of large signal buses or mixed-signal interfaces between PCBs within a compact connector envelope.
How does the TFC-137-02-F-D-A-K keying feature reduce assembly errors in multi-connector boards?
The keying feature adds a physical polarization element that blocks incorrect mating orientations. In PCB designs where several TFC-series connectors of the same size are placed adjacent to each other, such as in data acquisition systems with 74-signal I/O banks, keying ensures each connector mates only to its designated counterpart, preventing signal misrouting and potential component damage.
For which system types does a 74-position connector at 0.050" pitch provide the right interconnect solution?
A 74-position connector at 0.050" pitch like the TFC-137-02-F-D-A-K is well suited for FPGA mezzanine cards, DSP daughter boards, multi-channel ADC/DAC interface boards, and complex industrial I/O modules. These systems require routing dozens of digital or mixed-signal channels between a main carrier and a plug-in module within a constrained PCB area of under 10 cm².
When would an engineer choose TFC-137-02-F-D-A-K over a higher-pitch alternative for a 74-signal bus?
An engineer would select the TFC-137-02-F-D-A-K at 0.050" pitch over a 0.100" pitch alternative when PCB real estate is at a premium and weight minimization is required, such as in avionics test fixtures or compact industrial controllers. The 0.050" pitch reduces the connector's linear footprint by roughly 50%, freeing board space for signal conditioning or processing circuitry around the connector zone.
