FAQ
Q: What makes the round sheath design different from standard rectangular connectors?
A: The round sheath (cylindrical) housing provides 360° strain relief around the wire bundle, reducing stress at the connector entry point. It is also more compact in diameter for tight routing locations such as sensor mounting bosses and bulkhead pass-throughs.
Q: What is the difference between DJ3031-1.5-11 and DJ3031-1.5-21?
A: The "-11" suffix indicates a single locking tab, while "-21" indicates a dual locking tab for stronger retention. For engine-mounted sensors subject to vibration, the -21 variant is recommended.
Q: What terminals are compatible?
A: TE Connectivity / AMP 1.5mm series female terminals (part 1-968853-1 or equivalent) for 0.35–0.5mm² (AWG 22–20) wire. Terminals are sold separately.
