The orange housing and closed-end design with a polarizing key prevent incorrect insertion during assembly — the key aligns with the matching slot on the header, and the closed end stops the cable from pushing through. ## Termination and Retention for Harness Assembly No stripping or crimping is needed, which speeds up harness build for ribbon cable or discrete wire looms. ## Fit Check Against MTA-156 Headers This receptacle mates with any 11-position MTA-156 pin header at the same 0.156\" (3.96mm) pitch — the polarizing key and closed end are the alignment features. The locking ramp requires the header to have a matching latch feature for positive retention.","metaTitle":"TE MTA-156 4-643817-1, 11 Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE MTA-156 4-643817-1 11-position IDC receptacle, 0.156\" (3.96mm) pitch, tin contacts, locking ramp.
