Deutsch DT 6-Pin Waterproof Connector – OEM DT16-6S-KP01 | Female | IP67 | Heavy-Duty

The DT16-6S-KP01 (also listed as 571-DT16-6S-KP01) is a Deutsch DT series 6-pin female (socket) waterproof connector. The DT series is the industry standard for heavy-duty automotive, agricultural, and construction machinery harness applications, offering IP67 waterproofing and robust locking mechanisms designed for high-vibration environments.

DT Part Number Decoding: DT16-6S-KP01

• DT — Deutsch DT series (standard heavy-duty connector)
• 16 — Size 16 contacts (20–16 AWG)
• 6 — 6-pin configuration
• S — Socket (female) housing
• KP01 — Key position 01 (polarization key prevents mis-mating with other DT connectors in the same harness)

DT Series Key Position System

Deutsch DT connectors use a key position system (KP01–KP12) to prevent mis-mating between connectors of the same pin count in the same harness. The key position is a physical feature on the connector housing that only allows mating with the corresponding key position on the plug. This is critical in multi-connector harnesses where multiple 6-pin DT connectors are used for different circuits — the key position ensures the correct connector is mated to the correct circuit.

Common Applications

• Commercial truck engine harness (Cummins, Detroit Diesel, Volvo, Paccar)
• Agricultural equipment harness (John Deere, Case IH, New Holland, AGCO)
• Construction machinery harness (Caterpillar, Komatsu, Volvo CE)
• Marine diesel engine harness (Cummins Marine, Volvo Penta)
• Motorsport and performance vehicle custom harness

Assembly Requirements

• Contacts: Size 16 contacts (0462-201-16141 female / 0460-202-16141 male) — order separately
• Wedge lock: W6S wedge lock — insert after all contacts are seated to lock contacts in place
• Sealing plugs: Unused cavities must be sealed with cavity plugs to maintain IP67 rating
• Mating plug: DT16-6P-KP01 (6-pin male plug, same key position)

Frequently Asked Questions

Q: What is the mating connector for DT16-6S-KP01?
A: The mating male plug is DT16-6P-KP01 — same series, 6-pin, plug (male), key position 01. Always order matching key positions for mating pairs.

Q: Are contacts included?
A: No. The DT16-6S-KP01 is a housing-only connector. Size 16 contacts must be ordered separately.
