What the MX150 Right-Angle Header Delivers
The 34829-2001: This is a 20-circuit, dual-row right-angle header from the Molex MX150 sealed connector family, keyed A and molded in black. Key A polarization means the header only accepts a matching key A receptacle — you cannot mis-mate with a key B or C half. That polarization is set by the housing geometry, not a removable insert, so it is fixed at the mold. The 2x10 layout gives 20 signal or power positions in a compact footprint. Each circuit is rated for the MX150 contact system — typically up to 22 A per circuit depending on wire size and ambient temperature, though the exact derating is set by the terminal and wire gauge selected.
