48-Position Sealed Receptacle Housing for Harness Builds
Sealed Construction with Terminal Position Assurance
This housing is listed as sealed and includes Terminal Position Assurance (TPA) — a secondary lock that confirms each crimp terminal is fully seated in its cavity before the connector is mated. The TPA feature is critical in high-vibration applications like engine harnesses or off-road vehicle wiring, where a partially seated terminal can back out over time and open the circuit.
The 2366509-3 is a housing-only part — contacts are not included. You will need to source the matching NTS crimp tab terminals separately, then terminate them to your wire (typically 20-18 AWG for the NTS series, though confirm the exact wire range with the terminal datasheet). The housing mounts free-hanging (in-line), so no panel cutout or PCB footprint is required; it mates with the corresponding NTS plug housing of the same 48-position, 6-row layout. The locking ramp engages audibly when fully mated, giving the harness builder a positive click confirmation during assembly.
