This is the receptacle side of the connection; the mating plug housing and terminal selection determine the full interconnect.
Sealed Housing for Harsh Environments
The sealed construction means this housing is suited for underhood automotive, outdoor telecom, industrial washdown, or any location where the connector sees splash, spray, or condensation. The PBT-GF material resists creep at elevated temperatures and holds its dimensions through thermal cycling — important when the connector is part of a sealed harness that sees vibration and thermal shock.
For a production BOM, add the appropriate TE crimp terminal to the line item. Verify the terminal part number against the housing cavity layout before committing the BOM.
4-Row Layout and Free-Hanging Mounting
With 52 positions across 4 rows, this housing packs a high circuit count into a relatively compact in-line package. The free-hanging mounting style means it is not board-mounted — it terminates a cable harness and mates to a panel-mount or another in-line housing. The black PBT-GF body provides visual distinction and UV resistance for underhood or outdoor use. Bulk packaging is standard, suitable for hand-loading into harness assembly fixtures.
The closest functional sibling in the same family is the 1-2333134-5, a 30-position receptacle housing with 2 rows (vs 4 rows on the 1393450-3). Both are free-hanging, sealed, crimp-termination housings with a locking ramp fastening type. The 1-2333134-5 uses a 2.00 mm pitch and 3.30 mm row spacing, while the 1393450-3 does not have a listed pitch in the evidence — the row count difference (2 vs 4) is the primary selection driver. Choose the 1393450-3 when the circuit count requires 52 positions; drop to the 1-2333134-5 for a 30-circuit harness where a 2-row layout fits the connector cavity better.
