Three-Position Single-Row Receptacle Housing for Micro Quadlok
The TE Connectivity 2177231-1 is a 3-position, single-row receptacle housing from the Micro Quadlok series. The housing is free-hanging (in-line), so it terminates a cable harness directly — no PCB mount. It accepts female socket crimp terminals (sold separately), and the black PBT glass-filled body handles the usual under-hood and industrial cabinet environments.
Contacts Not Included — Order Crimp Terminals Separately
The listing explicitly notes contacts are not included. This housing ships empty — you need to order the matching Micro Quadlok female socket crimp terminals separately. The termination is crimp, so you'll also need the correct applicator tooling for your wire gauge. Common mistake: ordering only the housing and stalling the build waiting for terminals.
Pitch and Position Count Drive the Fit
The single-row layout means the housing is narrow, good for tight harness routing. But this is a crimp housing, not an IDC header — you terminate individual wires, not ribbon.
