The TC2050-IDC-NL-050-ALL-20 programming cable has an 0.050″ pitch ribbon connector suitable for ULINK2 and similar debuggers that use the Samtec FTSH-110-01 style micro-header. This uses the "No Legs" version of the TC2050 connector, ideally suited to production where short board connection times are required but also suitable for development.
The pin connections are 1-1 and pins 1-10 are connected, pins 11-20 are not connected in the cable.
Please refer to TC2050-IDC-NL datasheet for the PCB footprint information.
