9-Position 2.50mm Pitch Receptacle Housing for Crimp-Terminated Harnesses
The Molex 0511910900 is a 9-circuit, single-row receptacle housing from the 51191 series, designed for free-hanging (in-line) wire-to-board or wire-to-wire applications. It uses a 0.098" (2.50mm) pitch and accepts female socket crimp terminals that are ordered separately — the housing ships empty.
This is standard practice for field-terminated harnesses — the housing acts as the insulator and retention body, while the terminal provides the electrical connection.
