When space is tight but you still need Deutsch-grade waterproof reliability, the DTM series is your answer. Here's a complete guide to the miniature version of the world's most trusted automotive connector.

What Is the Deutsch DTM Series?

The DTM (Deutsch Miniature) series offers the same IP67 waterproof protection and vibration resistance as the full-size DT series in a significantly smaller and lighter package. Where a DT connector is designed for 12-20 AWG wire, the DTM handles finer gauges (22-20 AWG) with contacts rated at 7.5A each.

DTM vs DT: Key Differences

Feature DT Series DTM Series
Wire range 20-12 AWG 24-20 AWG
Current per contact 13A (size 16) 7.5A (size 20)
Housing size Standard ~40% smaller
Weight Standard ~50% lighter
IP rating IP67 IP67
Pin configs 2-12 positions 2-12 positions

DTM Applications

  • Motorcycles & powersports: Ideal for tight routing on bikes, ATVs, UTVs, and snowmobiles where DT connectors won't fit
  • Drones & UAVs: Weight-critical applications needing weatherproof connections
  • Precision agricultural sensors: Soil sensors, GPS antennas, small actuators
  • Marine electronics: Chart plotters, depth finders, VHF radio connections
  • Custom automotive: ECU sensor wiring, O2 sensor extensions, data logging connections

DTM Assembly Notes

  • Uses size 20 contacts - requires the W-HT-450-F crimp tool (different from DT's W-HT-1921)
  • Same wedge lock system as DT - slide in after contacts are seated
  • Sealing plugs available for unused cavities - essential for maintaining IP67 rating
  • DTM contacts are not interchangeable with DT contacts - different sizes
