Deutsch DTP 4-Pin Waterproof Connector – DTP06-4S / DTP04-4P | Black | IP67 | High-Current

The DTP06-4S / DTP04-4P are Deutsch DTP series 4-pin waterproof connectors for high-current power circuit applications. The DTP series is Deutsch’s high-power connector family, designed for circuits requiring up to 100A per contact with full IP67 waterproofing. The 4-pin configuration provides four independent high-current circuits in a single sealed connector. Available in Black housing color in Male (DTP04-4P) and Female (DTP06-4S) variants.

Deutsch DTP vs. DT vs. DTM – Which Series Do I Need?

• DT Series: General-purpose, IP67, size 16 contacts (up to 13A per contact). For signal and moderate-current circuits.
• DTM Series: Miniaturized DT, IP67, size 20 contacts (up to 7.5A per contact). For signal circuits in space-constrained applications.
• DTP Series (this product): High-power, IP67, size 8 contacts (up to 100A per contact). For battery feeds, alternator circuits, high-current actuators, and power distribution.

DTP Part Number Decoding

• DTP06-4S: DTP series / 06 = female (socket) housing / 4 = 4-pin / S = standard seal
• DTP04-4P: DTP series / 04 = male (plug) housing / 4 = 4-pin / P = plug
• DTP04-4P-LE07: Same male plug with LE07 = lever-lock end cap (prevents accidental unmating)

Common Applications

• Commercial truck: Battery-to-chassis power distribution, alternator output harness, starter motor relay circuit
• Agricultural equipment: Hydraulic pump motor power feed, PTO drive motor circuit, implement power harness
• Construction machinery: Hydraulic actuator power circuit, winch motor harness, auxiliary power distribution
• Motorsport: Battery isolator harness, PDM (Power Distribution Module) output circuits, fuel pump power feed
• Marine: Bilge pump power circuit, thruster motor harness, battery bank switching
• Military / defence: Vehicle power distribution harness, weapon system power feed

DTP Connector Assembly Requirements

• Contact size: Size 8 contacts (0460-215-08141 female / 0462-209-08141 male) — not included, order separately
• Wire gauge: 8–12 AWG (4.0–6.0mm²) for full 100A rating; use 10–12 AWG for 60–80A applications
• Crimp tool: Deutsch HDT-48-00 with size 8 die, or equivalent high-force ratchet crimp tool
• Wedge lock: DTP series uses a wedge lock (W4S for female, W4P for male) to secure contacts — insert after all contacts are seated
• Sealing plugs: Unused cavities must be sealed with cavity plugs (114017) to maintain IP67 rating

Frequently Asked Questions

Q: What is the maximum current rating for the DTP 4-pin connector?
A: Each contact is rated for up to 100A continuous with appropriate wire gauge (8 AWG / 6.0mm²). The 4-pin connector can therefore carry up to 400A total if all four contacts are used for power circuits. In practice, always derate to 80% of the rated current for continuous-duty applications.

Q: Are size 8 contacts included with the connector housing?
A: No. The DTP06-4S / DTP04-4P are housing-only. Size 8 contacts (0460-215-08141 female / 0462-209-08141 male) must be ordered separately.

Q: What is the difference between DTP04-4P and DTP04-4P-LE07?
A: DTP04-4P is the standard male plug. DTP04-4P-LE07 includes a lever-lock end cap that prevents accidental unmating under vibration — recommended for high-vibration applications such as agricultural equipment and construction machinery.
