What are the key features of TFC-106-02-LM-D-A-K?
- 24 positions (12 per row) at 0.050-inch pitch in a compact dual-row through-hole format
- Right-angle mid-mount (LM) termination for reduced connector stack height and low-profile board-edge mating
- Polarizing key (K) preventing incorrect insertion and protecting downstream circuitry from reversed signals
- Tiger Eye bifurcated contacts delivering dual-wipe reliability and low contact resistance in every position
What is TFC-106-02-LM-D-A-K used for?
The TFC-106-02-LM-D-A-K is suited for low-profile board-edge interconnects, compact industrial sensor modules, and mezzanine card configurations where 24 keyed, right-angle signal connections must be made at 0.050-inch pitch with minimal vertical clearance. Its mid-mount right-angle design and polarizing key make it ideal for field-replaceable module connectors in handheld test instruments, embedded control boards, and IoT gateway hardware where assembly error prevention is a priority.

Frequently Asked Questions
What does the LM suffix in TFC-106-02-LM-D-A-K indicate, and how does it differ from a standard right-angle L variant?
The LM suffix designates a right-angle mid-mount termination, meaning the connector body sits lower on the PCB compared to a standard L (right-angle) variant, resulting in a reduced stack height above the board surface. This mid-mount profile is typically around 50% lower than a standard right-angle configuration, which is critical in enclosures with tight lid clearances or in stacked PCB assemblies where vertical space is limited to a few millimeters above the board plane.
How does the polarizing key (K) on the TFC-106-02-LM-D-A-K protect a 24-channel sensor interface from wiring errors?
The K (key) option adds a physical tab to the connector housing that blocks insertion unless the mating connector is oriented correctly. On a 24-position dual-row connector carrying mixed signal types — such as 8 analog inputs, 8 digital I/O lines, and 8 power or ground pins — reversing orientation could apply power rails to analog signal inputs and damage sensor circuitry. The polarizing key makes a reversed connection mechanically impossible, reducing field-service error risk and protecting components rated for signals below 5 V.
Which compact embedded system designs are best served by the TFC-106-02-LM-D-A-K's 24-position count?
The 24-position format is a natural fit for microcontroller expansion headers, SPI/I2C/UART multi-peripheral breakout boards, and small sensor fusion modules where the design requires up to 24 signals — for example, 16 GPIO lines, 4 power pins, 2 communication bus lines, and 2 analog inputs. The low-profile mid-mount body keeps total PCB height below the connector to a minimum, enabling integration in handheld devices and DIN-rail-mounted control modules with enclosure heights under 30 mm.
When evaluating the TFC-106-02-LM-D-A-K against a surface-mount alternative at the same pitch, what are the key mechanical trade-offs?
The TFC-106-02-LM-D-A-K is a through-hole connector, so its pins extend through PCB vias and are soldered on the secondary side, providing significantly stronger mechanical attachment than surface-mount pads — important in connectors that experience repeated plug-and-unplug forces. Surface-mount alternatives of the same 0.050-inch pitch rely solely on solder joint shear strength, which can fatigue after fewer than 50 mating cycles under lateral load. The through-hole TFC-106-02-LM-D-A-K is therefore preferred in portable and handheld applications subject to mechanical stress, even though it requires via drilling and secondary-side soldering.
