Key Features
- 4-contact dual-row right-angle SMT layout on a 1.27 mm (0.050 inch) pitch for high-density low-profile board interconnects
- Gold (10 µin) over nickel (50 µin) contact finish on mating surfaces ensures low contact resistance and long insertion-cycle reliability
- RoHS-compliant construction with tin-over-nickel termination finish for lead-free solder compatibility in modern PCB assembly
Applications
FTSH-102-01-L-D-RA is used in compact embedded systems, wearable electronics, and board-to-cable harness connections where a low-profile right-angle SMT connector on a 1.27 mm grid is required. Its 4-contact dual-row design and gold mating finish make it suitable for debug headers, JTAG interfaces, and miniature sensor board interconnects that demand reliable, repeated mating cycles.

Frequently Asked Questions
What contact pitch and finish does FTSH-102-01-L-D-RA use, and how does this affect mating reliability?
FTSH-102-01-L-D-RA uses a 1.27 mm (0.050 inch) pitch with a gold (10 µin) over nickel (50 µin) contact plating on the mating surface. Gold plating at 10 µin provides corrosion resistance and low contact resistance over hundreds of mating cycles, which is critical for debug headers and field-service connectors that are plugged and unplugged repeatedly.
Why is the right-angle (RA) orientation of FTSH-102-01-L-D-RA important for enclosure-mounted PCB designs?
A right-angle SMT orientation rotates the mating axis 90 degrees so cables or mating boards exit parallel to the PCB surface. For panel-mount and enclosure-integrated boards where connectors face a rear or side wall, this right-angle orientation reduces required enclosure depth by eliminating the perpendicular mating clearance of vertical connectors, keeping the total assembly thickness under a few millimetres above the board.
In which low-pin-count debug or programming header applications does FTSH-102-01-L-D-RA serve as a compact alternative to larger connectors?
With only 4 contacts across 2 rows on a 1.27 mm pitch, FTSH-102-01-L-D-RA fits JTAG, SWD, or UART debug footprints on microcontroller boards where space is tight. Its body occupies approximately 3.4 mm × 5.3 mm, versus 7.6 mm × 8.5 mm for a standard 10-pin 2.54 mm JTAG header, making it the right choice for wearables, IoT nodes, and sub-compact MCU modules where board area is under 4 cm².
