Plug and Pins Only – Matching Set of Deutsch DT-3 Connectors (DT06-3S + DT04-3P) – (13 Amp)

Standardized 3-Pin Connectivity for Sensors and Actuators

The Deutsch DT-3 Connector Set is the ubiquitous standard for 3-wire automotive sensors and actuators. Whether you are wiring a Hall Effect sensor, a Throttle Position Sensor (TPS), or a pressure transducer, the DT-3 offers a secure, environmentally sealed interface rated for 13 Amps. This matching set includes the DT06-3S Plug and DT04-3P Receptacle, plus the necessary solid terminals and wedgelocks. It is designed for the custom harness builder who requires the flexibility to terminate wires to exact lengths, ensuring a clean, professional installation without the bulk of pre-terminated adapters.

Engineering Deep-Dive: Tri-Circuit Isolation

The triangular arrangement of the DT-3 housing is not just for compactness; it provides excellent structural rigidity and simplifies polarization, ensuring the connector cannot be forced in upside down. The housing is moulded from a durable thermoplastic that resists heat and chemical attack. The silicone rear grommet seals individually around each of the three wires, preventing moisture from wicking down the cable and corroding the contacts. This is particularly important for 3-wire sensors (5V Reference, Ground, Signal), where any corrosion-induced resistance on the ground or signal line can skew sensor readings and confuse the ECU.

Operational Benefits: Reliable Sensor Data

Accurate data is the foundation of engine tuning. A loose or corroded connector on a MAP sensor or TPS can lead to erratic idle, poor drivability, or engine damage. The Deutsch DT-3 system eliminates these variables with its positive locking latch and gas-tight crimp terminals. The solid contacts included in this kit resist vibration and thermal cycling better than stamped terminals, ensuring that the signal reaching your ECU is clean and consistent. The IP67 rating ensures that even if the sensor is mounted low in the engine bay or exposed to road spray, the electrical connection remains dry and secure.

Fitment and Application Scope

The 3-pin DT connector is the industry standard for:

• Pressure Sensors: Oil, Fuel, and Manifold Pressure (5V, Gnd, Sig).
• Position Sensors: TPS, Pedal Position, Suspension Travel.
• Hall Effect Sensors: Crank and Cam triggers.
• Solenoids: Some industrial control valves.

Technical Specifications

Summary & Includes

The HT-031113 Kit is the reliable choice for critical 3-wire sensor and actuator connections. It ensures that your engine management system receives the accurate data it needs.

Includes:

• 1 x DT04-3P Connector (Receptacle)
• 1 x DT06-3S Connector (Plug)
