It belongs to the 2106431 base series, sharing the 4.00 mm cable and board-side pitch that keeps the wire spacing aligned with the PCB land pattern — no pitch mismatch between the cable exit and the solder pads. The natural housing carries a feed-through feature that lets a daisy-chain wire pass through the connector body without terminating at this position, useful for distributing a common signal or power rail across multiple connectors in a harness. ## Termination and Harness Assembly IDC termination on 18 AWG wire requires a proper press tool that drives the insulation-displacing slot through the jacket and onto the conductor — no wire stripping or crimping. The feed-through feature lets the installer pass a continuous wire through the connector body; the IDC slot only contacts the wire at the position where the terminal is pressed, leaving the rest of the wire uninterrupted for the next connector in the chain. Single-row, 4-position layout keeps the termination force per wire manageable with a hand tool, though a pneumatic or bench press is recommended for consistent slot penetration across all four positions.","metaTitle":"TE 2106431-4 IDC Connector, 4 Pos 18 AWG SMD RA","metaDescription":"TE 2106431-4 wire IDC connector, 4 positions, 18 AWG, 4.00 mm pitch, SMD right-angle, tin contacts, ROHS3, active.
