How to Read Deutsch DT, DTM, and DTP Connector Part Numbers

Understanding Deutsch connector part numbers allows you to quickly identify the correct connector, terminals, and configuration for your application.


🔍 Example Breakdown

Example: DTM06-2S

Each section of the part number has a meaning:

  • DTM → Connector series
  • 06 → Plug housing
  • 2 → Number of positions
  • S → Socket contacts

🧩 Step 1: Identify the Series

Series Use Case Size
DTM Sensors / low current Small
DT General wiring Medium
DTP High current Large
DTHD Heavy-duty power Extra large

👉 Start here first—this determines everything else.


🔌 Step 2: Plug vs Receptacle

Code Type
04 Receptacle (female housing)
06 Plug (male housing)

Example:

  • DT04 = Receptacle
  • DT06 = Plug

👉 These must match to connect properly.


🔢 Step 3: Number of Positions

The number tells you how many pins:

  • 2 = 2-pin
  • 3 = 3-pin
  • 4 = 4-pin

👉 Both connectors must have the same number.


⚙️ Step 4: Contact Type

Code Meaning
P Pin contacts (male terminals)
S Socket contacts (female terminals)

Important:

  • Plug housing → uses socket (S)
  • Receptacle → uses pin (P)

👉 This is where people often make mistakes.


🧠 Visual Example: Full Breakdown

DTM06-2S

  • DTM = Series
  • 06 = Plug
  • 2 = Positions
  • S = Socket

⚡ DTP (High Current) Example

DTP06-2S

  • DTP = High current connector
  • 06 = Plug
  • 2 = Positions
  • S = Socket

👉 Used for:

  • Power circuits
  • Fans
  • Pumps
  • High-load devices

⚠️ Common Mistakes

  • Mixing plug vs receptacle
  • Wrong contact type (P vs S)
  • Wrong series for current load
  • Mismatched pin counts

🧰 Why This Matters

Choosing the correct part number ensures:

  • Proper fitment
  • Reliable electrical connection
  • Long-term durability

👉 It also prevents ordering the wrong parts.
