Product Details
| Core Specifications | Engineering Advantages | Operational Benefits |
| RD01 Reduced Diameter Rear Wire Seal | Features a downsized internal diameter on the rear silicone seal, specifically engineered to tightly grip thin-walled automotive wires (such as TXL or thin-insulated wires). | Eliminates moisture and dust bypass along downsized cable jackets, preventing capillary water ingress, harness corrosion, and electrical failure. |
| 13A Heavy-Duty Contact Architecture | Engineered to support continuous electrical current up to 13 Amps safely across all 3 circuits when populated with matching size 16 contacts. | Delivers stable power and signal routing for critical under-hood components like sensors, injectors, and fluid pumps without thermal degradation. |
| Rugged Thermoplastic Engineering Shell | Molded from industrial-grade thermoplastic that resists mechanical stress, impact, and chemical exposure from engine fluids. | Extends the functional lifespan of vehicle electrical harnesses, preventing cracked housings and minimizing diagnostic field downtime. |
| Fully Intermateable DT Series Compatibility | Built to exact standard dimensions, ensuring 100% mechanical drop-in cross-compatibility with equivalent industry 3-pin connectors. | Provides total sourcing flexibility, bypassing factory supply bottlenecks and lowering BOM costs without requiring wire harness redesigns. |

Q1: What is the main structural difference between the standard AT04-3P and the AT04-3P-RD01?
The core difference lies in the diameter of the rear wire insulation entry seal. The standard AT04-3P is designed for standard thick-walled automotive wires, whereas the AT04-3P-RD01 features an RD01 reduced diameter seal. This smaller seal opening is specifically engineered to compress tightly against modern thin-walled wires (such as TXL or thin-jacketed cables), ensuring a reliable waterproof barrier that standard housings cannot provide on narrow gauge insulations.
Q2: Does the AT04-3P-RD01 part number include the male pin contacts and secondary wedge locks?
No. The AT04-3P-RD01 part number specifies only the empty gray thermoplastic receptacle housing with its integrated thin-wire rear seal. To complete the assembly for a wire harness build, you must select and purchase the male crimp pins (Size 16) and the corresponding secondary locking wedge (part number AW3P) separately based on your project requirements.
Q3: Is this Amphenol SINE AT series receptacle fully interchangeable with Deutsch DT components?
Yes, absolutely. The Amphenol AT04-3P-RD01 is precision-engineered to match the dimensions, mechanical mating tracks, and electrical thresholds of the standard Deutsch DT04-3P series. It mates seamlessly with Deutsch DT06-3S plugs and accepts standard Deutsch-style size 16 contacts, serving as a reliable and cost-effective drop-in replacement.
