What are the key features of TFM-109-02-LM-D-RA?
- 0.050 inch (1.27 mm) pitch dual-row right-angle (RA) Tiger Eye terminal strip with 18 total positions, 9 per row, for horizontal PCB signal egress
- LM surface-mount termination style provides a low mounting profile enabling board-edge connections in enclosures with tight vertical clearance below 5 mm
- High-reliability Tiger Eye contact design maintains stable contact resistance from -55°C to +125°C for industrial and defense-grade applications
What is TFM-109-02-LM-D-RA used for?
TFM-109-02-LM-D-RA is used in right-angle board-edge interconnect applications where signals must exit a PCB horizontally without increasing board height, such as panel-mount interfaces in industrial instruments and embedded control systems. The 18-contact dual-row layout at 0.050 inch pitch enables compact signal breakout for low-pin-count interfaces including serial buses, sensor headers, and programming connectors. Its LM surface-mount termination and right-angle orientation suit slim enclosure designs where vertical stacking is not feasible.

Frequently Asked Questions
What is the total pin count and pitch of TFM-109-02-LM-D-RA, and how is the RA suffix relevant?
TFM-109-02-LM-D-RA provides 18 total contact positions in a dual-row right-angle layout with 9 pins per row at 0.050 inch (1.27 mm) pitch. The RA suffix indicates right-angle orientation, meaning the connector body lies parallel to the PCB surface and signals exit horizontally, which is ideal for panel-mounted instruments and slim enclosure designs requiring lateral signal routing.
For a compact industrial sensor interface board, how does TFM-109-02-LM-D-RA's 18-position layout fit the design?
With 18 contact positions at 0.050 inch pitch in a dual-row right-angle configuration, TFM-109-02-LM-D-RA can accommodate a full SPI or I2C bus plus up to 12 additional analog or digital sensor channels. The right-angle body keeps the mated height below 5 mm, fitting slim DIN-rail enclosures or compact panel-mount instrument housings where vertical clearance is limited.
How does the LM termination style of TFM-109-02-LM-D-RA affect PCB land pattern and soldering process?
The LM termination style uses surface-mount gull-wing leads that extend from the connector body parallel to the PCB, producing a low-profile footprint requiring standard SMT reflow soldering at typical peak temperatures of 245°C to 260°C for lead-free paste. This approach eliminates through-hole drilling, simplifies the 0.050 inch pitch PCB land pattern, and is fully compatible with automated optical inspection after reflow, reducing assembly cost compared to through-hole variants.
