Hybrid Plug for Mixed Power and Signal Harnesses
The Molex 1600775002 is a 10-position hybrid plug from the MX150 160077 series, laid out as 6 signal circuits plus 4 power circuits in a single 2-row housing. That split — six smaller-gauge terminals for sensors or control signals alongside four heavier terminals for the main load — is what sets this connector apart from a uniform-pin-count plug. It saves a separate power distribution block in the harness, because the power pair runs through the same connector body as the signal lines. The 0.138" (3.50mm) pitch is standard for the MX150 family, giving enough room between contacts for the 600V creepage path without blowing up the connector footprint.
What the 10 (6 + 4 Power) Layout Means for Your Harness
The hybrid position count is the main decision point: 10 positions total, but only 6 are signal contacts and 4 are power contacts.
No official second-source cross-reference exists, but the MX150 series is widely used, so the mating receptacle and terminals are stocked across multiple channels.
The mating receptacle is a separate order — typically an MX150 160077-series receptacle housing with the same 10 (6 + 4 Power) position layout and Key B keying.
