38-Circuit Mini50 Header — Gray Pol B Keying in Tray
The 34958-0381: This is a 38-circuit vertical pin header from the Molex Mini50 family, molded in gray with Pol B keying and shipped in a tray. Pol B keying prevents mis-mating with a Pol A receptacle, a useful safeguard when multiple similar headers sit on the same board. The gray housing color distinguishes it visually from other keying variants in the same series.
