DT Series Technical Manual
Product Line Overview
Deutsch  DTM Series  of transportation   connectors  feature  a 
miniature contact with an enhanced design based on the world 
class, field-proven Deutsch “DT Series”.
The  DTM  is  the  connector to  be  used  in  harsh  environmental 
applications where reliable signal circuits are critical to operating 
performance.  Typical  applications  include  on  or  around  the 
engine, the transmission and under the hood. In fact, everywhere 
data  signals  or  critical  electronic  circuits  go,  the  field  proven 
Deutsch design of the DTM will provide reliable peak connector 
performance.
The low cost, size 20 contacts terminate AWG 16 to 22 gauge 
wire (0.5mm
2
 to 1.5mm
2
). Closed entry socket (female) contacts 
featuring spring action fingers are protected by a stainless steel 
hood. This allows for positive axial alignment while mating and 
prevents probe damage during testing.
Thermoplastic housings offer a wide operating temperature 
range  (-55
0
 C  to  +125
0 
C).  Silicone  rear  wire  and  internal 
peripheral interface seals allow the DTM to withstand moisture 
and fluids.
Deutsch  DT Series  of  environmentally-sealed,  connectors  are 
designed specifically for cable to cable applications on the engine 
or transmission, under the hood, on  the  chassis  or  in  the  cab. 
Where  signal  level  circuits  in  harsh  environmental  conditions, 
where even a small degradation in connection may be critical, 
the Deutsch DT Series general purpose connectors will provide 
the reliability and performance at the lowest cost. 
Thermoplastic (-55
0 
C to + 125
0 
C rated) housings and silicone 
seals are used to allow the connector to withstand conditions 
of extreme temperature  and  moisture.  The  connector may be 
employed with either solid-copper crimp type contacts for critical 
circuits or  budget-minded  stamped  and  formed contacts.  In 
either selection, the spring action is designed in the socket and 
shrouded by a stainless steel hood that provides closed entry for 
positive  axial alignment  during  mating, and  eliminates  probe 
damage from occurring. Contact insertion and withdrawal require 
no special tools and are retained in locked position by dielectic 
fingers,  molded  as  an  integral  part  of  the  housing.  Secondary 
locks are assembled  at  the  mating  interfaces.  If  by  chance  the 
secondary locks are not  properly seated during assembly, they 
will be  pressed into locked  position  during  the  mating of  the 
connector. 
Deutsch DT Series
Deutsch DTM Series 
These  standard  “DT”  receptacle  shells  feature  internal  pin  type 
contact  buss  bar  arrangements  that  allow  common  connections 
from 3 to 12 size 16 contacts. Buss bars are available in standard 
nickel or gold to match common Deutsch Industrial contacts.
Other  features  include  the  use  of  standard  “DT”  plugs  to  mate 
with these  environmental receptacles. Plugs  with  any  Deutsch 
modification are intermatable. 
Deutsch DT Bussed Series
Deutsch DTP Series
Building on both the  DT and DTM design  strengths, the  DTP 
connector line was developed to fill the need for higher amperage, 
multi-pin,  inexpensive  connectors.  The  series  meets  the  same 
specifications as the DTM and DT but offers the designer the ability 
to use multiple 12 gauge contacts, each with a 25 amp continuous 
capacity, within a single shell.
Based  on  the  DTM  overall  design,  it  offers  the  protected interfacial 
seal located within the receptacle shell. Standard multi-seal grommet 
is used in both the plug and receptacle. Currently available in two and 
four pin configurations.
Deutsch DTHD Series
Deutsch developed the DTHD Series for those applications requiring a 
complete, environmentally sealed, single power circuit termination. 
DTHD plugs and receptacles can be permanently assembled with 
thermoplastic end caps that prevent removal of  the  silicone  wire 
seal grommets. Designed for diesel engine, electronic fuel injectors, 
automatic  transmissions,  ABS  brakes  and  other  applications  that 
involve fuel and oil exposure. These end caps provide the additional 
reliability required for critical wiring circuits.
