The dual-row layout at a 4.20mm pitch gives enough room between circuits for the current these connectors typically carry, while keeping the overall plug width manageable for a 20-position bundle.
Inline Mount, Crimp Termination — Contacts Sold Separately
This housing is a free hanging (in-line) plug, meaning it terminates the wire harness end and mates to a board-mounted header or another inline receptacle. Termination is crimp-style, so you'll need the matching VAL-U-LOK crimp terminals — the housing ships with contacts not included, a detail that catches first-time buyers off guard if they assume the plug arrives ready to wire.
Glow Wire Compliance and Locking Ramp Retention
Two features on this housing that matter for application selection: glow wire compliance and the locking ramp. The glow wire rating means the housing material (PA nylon) has been tested to resist ignition under the glow wire test — this is a regulatory gate for white goods, HVAC controls, and lighting ballasts. Without it, the plug can walk off the header over time as the harness flexes.
The 20-position 2-2296206-0 sits in the same VAL-U-LOK family as the 10-position 1-2296206-0, sharing the same 4.20mm pitch, dual-row layout, and locking ramp design. Both housings use the same crimp terminals and mate with the same header series, so a change in position count doesn't force a retool of the wire processing line.
