3-Position Plug Housing for Wire-to-Wire Harnesses
The TE Connectivity 1-1903414-1 is a 3-position plug housing from the Grace Inertia, GIC series. It is a free-hanging (in-line) connector meant for wire-to-wire or wire-to-board harness assemblies where a positive-lock connection is needed. The 9.00 mm pitch gives generous spacing between terminals — wide enough that crimp tooling and wire routing in the harness are straightforward, even with larger-gauge wire.
Glow Wire Compliance and Latch Lock Retention
This housing carries a glow wire compliant rating — a safety certification that means the nylon housing resists ignition under electrical fault conditions, which is a requirement for many household appliance and HVAC applications. The latch lock fastening type provides audible positive retention when mated with the matching receptacle, so the connection stays together under vibration in a vehicle or on a moving machine arm. The single-row, 3-position layout keeps the harness narrow and easy to route in tight spaces.
Contacts Not Included — Order Separately
The listing explicitly notes Contacts Not Included. This housing accepts female socket crimp terminals that must be ordered as a separate line item. The contact termination is crimp, so you will need the matching TE socket terminal (typically from the Grace Inertia terminal family) and the correct crimp tool for the wire gauge you are running. Ordering the housing alone and forgetting the terminals is the most common stockroom mistake on this part — stock both halves or neither.
