The 1658613-2: IDC termination — the contacts pierce the ribbon cable insulation in a single press operation, no wire stripping or crimping. Accepts 26-28 AWG stranded or solid conductors. The 2-row layout matches standard 0.054-inch pitch ribbon cable. The unthreaded housing/shell flange allows panel mounting with screws (not included).
Grounding and Shielding
Includes feed-through and grounding indents — the indents on the steel shell make contact with the mating receptacle's shell, providing shield continuity without dedicated ground pins. This helps bleed common-mode noise and EMI before it reaches the signal contacts.
