Key Features
- 32 positions (16 per row) at 0.050-inch pitch with gold mating contacts on phosphor bronze for excellent conductivity
- Tiger Eye bifurcated contact geometry providing dual-wipe low-resistance connection across all 32 pins
- Tape-and-reel (TR) packaging enabling high-volume automated pick-and-place assembly with minimal handling
- Polarizing key (K) preventing incorrect connector orientation and protecting downstream signal integrity
Applications
The TFC-116-02-F-D-A-K-TR is used in compact PCB-to-PCB interconnects, microcontroller peripheral headers, and field-programmable logic expansion boards requiring 32 reliable through-hole signal connections at 0.050-inch pitch with guided mating. Its gold mating contacts and tape-and-reel format make it ideal for automated high-volume production of industrial sensor interfaces, embedded communication modules, and data acquisition daughterboards where mating reliability and assembly efficiency are both priorities.

Frequently Asked Questions
What contact finish does the TFC-116-02-F-D-A-K-TR use, and why does it matter for connector reliability?
The TFC-116-02-F-D-A-K-TR uses gold (3 micro-inch minimum) mating contact finish on the Tiger Eye contacts and matte tin on the solder terminations. Gold provides excellent oxidation resistance and low, stable contact resistance over thousands of mating cycles, which is critical for the 32-position fine-pitch array where a single high-resistance contact can corrupt a data or control signal. The matte tin termination on the through-hole tail is fully compatible with standard SAC305 wave and selective solder processes at temperatures up to 260°C.
How does the tape-and-reel (TR) packaging of the TFC-116-02-F-D-A-K-TR improve manufacturing efficiency?
Tape-and-reel packaging presents each connector pre-oriented in a carrier tape at a defined pitch, allowing automated pick-and-place machines to load and place parts at speeds typically exceeding 3,000 placements per hour without operator intervention. For a 32-position through-hole connector, this eliminates manual tray-feeding, reduces placement errors, and lowers overall PCB assembly cost per unit in production runs above 500 boards. It also prevents electrostatic damage during handling since the reel provides a controlled handling environment.
In which 32-signal embedded control designs does the TFC-116-02-F-D-A-K-TR offer the best fit?
The 32-position format matches common microcontroller I/O bus requirements: for example, a 16-bit parallel data bus plus 8 address lines plus 8 control and power lines can be carried on a single TFC-116-02-F-D-A-K-TR at 0.050-inch pitch. The connector is also well-suited for CAN bus gateway modules with multiple I/O lines, embedded vision camera interfaces, and motor drive enable-and-feedback headers where pin counts fall in the 24-to-40-position range and reliable gold contacts are required.
What does the polarizing key (K) on the TFC-116-02-F-D-A-K-TR prevent, and how critical is this for mixed-voltage boards?
The K option adds a mechanical polarizing key to the connector housing that makes it physically impossible to mate the connector in the reversed orientation. On boards that carry both 3.3 V and 5 V logic lines across the 32 positions, incorrect insertion could apply 5 V signals to 3.3 V-tolerant ICs and cause immediate or latent device damage. The keying feature effectively eliminates this class of assembly error at zero additional cost in automated production, making it a standard choice for any mixed-voltage or mixed-signal 32-pin interface.
