Key Features
- 46-position dual-row Tiger Eye contacts at 0.050" (1.27 mm) pitch provide ultra-high signal density with consistent sub-20 milliohm contact resistance across all positions
- Keyed (-K) polarization prevents reverse mating of identical adjacent connectors on high-density PCBs with multiple fine-pitch interfaces
- Tape-and-reel (-TR) packaging enables automated pick-and-place assembly at high production volumes with repeatable placement accuracy for 46-position fine-pitch connectors
Applications
The TFC-123-02-L-D-A-K-TR is designed for automated high-volume production of embedded computing boards, communications modules, and portable test equipment requiring 46-channel fine-pitch signal interconnects with assembly error prevention. Its keyed housing ensures correct connector orientation during factory assembly of multi-connector PCBs where several TFC connectors may be placed within close proximity. The 0.050" pitch and tape-and-reel format make it the preferred choice for compact daughter-card and cable-to-board interfaces in industrial IoT gateways and wireless communication modules.

Frequently Asked Questions
How does the keying (-K) feature on the TFC-123-02-L-D-A-K-TR improve assembly yield in multi-connector PCB designs?
The -K keying option on the TFC-123-02-L-D-A-K-TR adds a physical asymmetric feature to the 46-position housing that prevents mating with an incorrectly oriented or adjacent cable connector. On PCBs with 3 or more TFC connectors within 5 mm of each other at 0.050" pitch, keying reduces connector swap errors to near zero during factory assembly, improving first-pass yield and avoiding the cost of reworking miswired 46-channel harnesses.
What production throughput advantage does the TFC-123-02-L-D-A-K-TR's tape-and-reel packaging provide over bulk-packaged alternatives?
Tape-and-reel (-TR) packaging of the TFC-123-02-L-D-A-K-TR allows automated pick-and-place machines to place 46-position fine-pitch connectors at rates exceeding 3,000 parts per hour with positional accuracy under 0.1 mm. Bulk-packaged variants require manual feeder loading or vibratory bowl feeders, reducing throughput to under 500 placements per hour for connectors with asymmetric housing profiles like keyed fine-pitch parts.
When is TFC-123-02-L-D-A-K-TR preferred over TFC-123-02-LM-D-A for a 46-position interface in automated assembly?
The TFC-123-02-L-D-A-K-TR is preferred when the PCB assembly uses automated pick-and-place equipment (requiring tape-and-reel) and when multiple identical connectors are placed within 10 mm of each other (requiring keying). The TFC-123-02-LM-D-A with latch mount is better suited for prototyping or low-volume builds where manual handling of bulk-packaged parts is acceptable and a keyed variant is not needed.
