Key Features
- 22-position dual-row terminal strip with 0.050" (1.27 mm) pitch for compact low-channel-count board-to-board signal interfaces
- Low-profile LM contact style minimizes stack height in multi-board embedded assemblies using 11 positions per row
- Kinked (K) through-hole tail provides mechanical pre-solder retention across all 22 positions during PCB assembly
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly in high-volume production workflows
Applications
The TFC-111-02-LM-D-A-K-TR is designed for low-to-mid channel count board-to-board signal interfaces in sensor modules, embedded microcontroller boards, and compact industrial I/O panels requiring 22 positions at 0.050" pitch. The low-profile contact style suits tightly stacked PCB assemblies where minimizing board clearance is a design constraint. Tape-and-reel packaging supports automated placement in volume manufacturing for cost-sensitive applications.

Frequently Asked Questions
What pitch and position count does the TFC-111-02-LM-D-A-K-TR offer?
The TFC-111-02-LM-D-A-K-TR is a 22-position dual-row Tiger Eye terminal strip with 0.050" (1.27 mm) pitch, providing 11 positions per row. This lower channel count suits compact sensor boards, microcontroller expansion headers, and small industrial I/O modules where only a limited number of signal lines are required.
How does the kinked tail (K) on the TFC-111-02-LM-D-A-K-TR prevent assembly defects?
The kinked through-hole tail mechanically locks the TFC-111-02-LM-D-A-K-TR into the PCB via hole pattern before soldering, preventing lateral shift or rotation across the 22-position 1.27 mm pitch layout. This pre-solder mechanical retention reduces connector misalignment and cold-joint defects during wave or hand soldering of the 11-position dual-row pattern.
When is the TFC-111-02-LM-D-A-K-TR preferred over a 34- or 50-position terminal strip?
The TFC-111-02-LM-D-A-K-TR is the better choice when an interface only requires 22 signal connections at 0.050" pitch, as it occupies less PCB area and costs less per unit than larger-position variants like TFC-117 or TFC-125. This makes it ideal for low-channel-count sensor adapters, embedded accessory boards, and compact I/O expanders where BOM cost minimization is a priority.
What production benefits does tape-and-reel (TR) packaging provide for the TFC-111-02-LM-D-A-K-TR?
Tape-and-reel packaging allows pick-and-place machines to automatically place the TFC-111-02-LM-D-A-K-TR's 22-position 0.050" pitch connector with high repeatability and speed, reducing manual handling errors and assembly cycle time. For high-volume production runs of embedded boards and sensor modules, TR packaging also lowers per-unit handling cost compared to loose or tray formats.
