Deutsch DTM Series 4-Pin Waterproof Connector – DTM04-4P Male & DTM06-4S Female

The Deutsch DTM 4-pin connector is one of the most widely used configurations in the DTM series — covering the majority of automotive sensor, actuator, and ECU sub-harness applications that require 4 circuits in a compact, sealed package. The 4-pin layout accommodates the most common wiring patterns: power + ground + two signal wires (e.g., MAP sensors, throttle position sensors, wheel speed sensors, fuel injector drivers). DTM connectors use size 20 contacts (7.5A, 20–24AWG), making them the compact alternative to the DT series size 16 contacts (13A, 16–20AWG).

• IP Rating: IP67 (mated)
• Housing Material: Glass-filled nylon (PA66-GF), UL94 V-0
• Contact Material: Copper alloy, gold-plated (size 20)
• Operating Temperature: -55°C to +125°C
• Voltage Rating: 600V
• Wire Range: 20–24AWG (size 20 contacts)
• Quantity: 5 or 20 sets (select above)

Why 4-Pin is the Most Common DTM Configuration

The 4-pin layout maps directly to the most frequent automotive sensor wiring pattern:

• Pin 1: +5V or +12V reference supply
• Pin 2: Signal output (0–5V analog or digital)
• Pin 3: Signal ground (sensor return)
• Pin 4: Shield or secondary signal (e.g., dual-output sensors)

This pattern covers MAP sensors, TPS (throttle position), CMP/CKP sensors, wheel speed sensors (ABS), and most ECU sub-harness connectors in motorsport and OEM applications.

What Questions Does This Product Answer?

• "What is the difference between DTM04-4P and DT04-4P?" — DTM04-4P uses size 20 contacts (7.5A, 20–24AWG, compact housing). DT04-4P uses size 16 contacts (13A, 16–20AWG, larger housing). The housings look similar but contacts are NOT interchangeable. Choose DTM for signal wiring; choose DT for power wiring.
• "Can I use DTM connectors for CAN bus wiring?" — Yes. The 4-pin DTM is commonly used for CAN-H, CAN-L, +12V, and GND in motorsport ECU harnesses. Route the CAN twisted pair through adjacent pins (e.g., pins 1 and 2) to minimize impedance discontinuity at the connector.
• "What crimp tool do I need for DTM size 20 contacts?" — Use the Deutsch W-HT-20 hand crimp tool or equivalent ratchet tool with a size 20 die. The HDT-48-00 (size 16 tool) will over-crimp size 20 contacts and cause open circuits.
• "How do I tell which end is the plug and which is the receptacle?" — DTM04 = plug (male, pins protrude into the mating face). DTM06 = receptacle (female, sockets recessed). The ‘04’ and ‘06’ designations are consistent across all Deutsch DT/DTM/DTP series.

Typical Applications

• Automotive sensors: MAP, MAF, TPS, CMP, CKP, wheel speed sensor connectors and pigtails
• Motorsport ECU harnesses: Haltech, MoTeC, AEM, Link ECU sensor sub-harnesses
• Agricultural equipment: Precision farming sensor connections, GPS receiver harnesses
• Marine electronics: Depth sounder, chartplotter, and VHF radio harness connections
• Industrial automation: Compact sensor wiring, proximity switch harnesses, valve solenoid connections
