Key Features
- 4-position dual-row 1.27 mm pitch right-angle terminal strip enables horizontal board-to-board signal routing at compact 0.050 inch spacing
- 15 µin gold-over-50 µin nickel contact finish ensures low contact resistance and corrosion resistance over 1000+ mating cycles
- Tiger Eye high-reliability contact design provides consistent normal force for stable electrical connection under vibration
- Right-angle (RA) orientation allows mating connectors to mate parallel to the PCB, minimizing connector height in shallow enclosures
Applications
TFM-102-01-L-D-RA is used in space-constrained right-angle board-to-board signal connections for compact embedded systems, sensor modules, and portable medical instruments where 4 signal lines must be routed at 1.27 mm pitch with the mating direction parallel to the host PCB. The gold-plated Tiger Eye contacts ensure reliable signal transmission in vibration-prone industrial and handheld device environments.

Frequently Asked Questions
What is the contact finish specification of TFM-102-01-L-D-RA and why does it matter?
TFM-102-01-L-D-RA uses 15 µin (microinch) gold over 50 µin nickel on mating contacts and tin over nickel on termination contacts. The gold finish provides contact resistance typically below 10 mΩ and resists oxidation over 1000+ mating cycles, ensuring reliable signal continuity in low-voltage digital and analog circuits.
How does the right-angle orientation of TFM-102-01-L-D-RA help in shallow PCB enclosure designs?
The right-angle (RA) orientation of TFM-102-01-L-D-RA allows the mating connector to engage parallel to the PCB surface rather than perpendicular, reducing the vertical stack height by approximately the connector body depth of 0.29 inches. This is critical for low-profile enclosures, panel-mount sensor modules, and portable instruments where overall device thickness must be minimized.
For a 4-channel sensor interface board, why choose a 1.27 mm pitch connector like TFM-102-01-L-D-RA over a 2.54 mm version?
A 4-channel sensor interface board benefits from TFM-102-01-L-D-RA's 1.27 mm pitch because the smaller footprint—with a body length of 0.225 inches—allows the connector to fit on a miniaturized PCB alongside dense analog circuitry. Compared to a 2.54 mm pitch equivalent occupying roughly twice the board length, the 0.050 inch pitch frees space for filtering capacitors and ESD protection components adjacent to the 4 sensor signal contacts.
