<strong>DT</strong> <strong>Series</strong> <strong>Technical</strong> <strong>Manual</strong><strong>DT</strong> <strong>Series</strong> <strong>Technical</strong> <strong>Manual</strong>Product Line OverviewDeutsch <strong>DT</strong>M <strong>Series</strong>Deutsch <strong>DT</strong>M <strong>Series</strong> of transportation connectors feature aminiature contact with an enhanced design based on the worldclass, field-proven Deutsch “<strong>DT</strong> <strong>Series</strong>”.The <strong>DT</strong>M is the connector to be used in harsh environmentalapplications where reliable signal circuits are critical to operatingperformance. Typical applications include on or around theengine, the transmission and under the hood. In fact, everywheredata signals or critical electronic circuits go, the field provenDeutsch design of the <strong>DT</strong>M will provide reliable peak connectorperformance.The low cost, size 20 contacts terminate AWG 16 to 22 gaugewire (0.5mm 2 to 1.5mm 2 ). Closed entry socket (female) contactsfeaturing spring action fingers are protected by a stainless steelhood. This allows for positive axial alignment while mating andprevents probe damage during testing.Thermoplastic housings offer a wide operating temperaturerange (-55 0 C to +125 0 C). Silicone rear wire and internalperipheral interface seals allow the <strong>DT</strong>M to withstand moistureand fluids.Deutsch <strong>DT</strong> <strong>Series</strong>Deutsch <strong>DT</strong>P <strong>Series</strong>Building on both the <strong>DT</strong> and <strong>DT</strong>M design strengths, the <strong>DT</strong>Pconnector line was developed to fill the need for higher amperage,multi-pin, inexpensive connectors. The series meets the samespecifications as the <strong>DT</strong>M and <strong>DT</strong> but offers the designer the abilityto use multiple 12 gauge contacts, each with a 25 amp continuouscapacity, within a single shell.Based on the <strong>DT</strong>M overall design, it offers the protected interfacialseal located within the receptacle shell. Standard multi-seal grommetis used in both the plug and receptacle. Currently available in two andfour pin configurations.Deutsch <strong>DT</strong> Bussed <strong>Series</strong>These standard “<strong>DT</strong>” receptacle shells feature internal pin typecontact buss bar arrangements that allow common connectionsfrom 3 to 12 size 16 contacts. Buss bars are available in standardnickel or gold to match common Deutsch Industrial contacts.Other features include the use of standard “<strong>DT</strong>” plugs to matewith these environmental receptacles. Plugs with any Deutschmodification are intermatable.Deutsch <strong>DT</strong>HD <strong>Series</strong>MATERIAL SPECIFICATIONSPlug/ReceptacleShell: ThermoplasticWedge: ThermoplasticGrommet: Silicone RubberContactsPin:Socket:Finish:Sealing PlugsThermoplastic: (All sizes)Copper AlloyCopper AlloyNickel (optional - gold) PlatedGENERAL SPECIFICATIONSDielectric Withstanding VoltageCurrent leakage less than 2 milliamps at 1500 VACInsulation Resistance:1000 megohms minimum at 25 0 C.Current Rating (Contact current rating @ 125 0 C (continuous)Size 20: 7.5 ampsSize 16: 13 ampsSize 12: 25 ampsSize 8: 60 ampsSize 4: 100 ampsThermal Cycle:No cracking, chipping or leaking after 20 test cycles from-55 0 C to +125 0 C.Durability:No electrical or mechanical defects after 100 cycles ofengagement and disengagement.CONTACTSIZE20CONTACT RESISTANCEWIRE GAUGEAWG(mm 2 )20 (.50)16 (1.0)16 20 (.50)18 (.80)16 (1.0)Test Current(Amps)Resistance (mV)SolidsResistance (mV)Stamped & Formed7.5 60 10014 (2.0) 13 60 10012 14 (2.0) 18 60 10012 (3.0) 25 60 1008418 (.80)8 (8.60)10 (5.60)7.5 60 1007.5 60 1007.5 60 10010 60 10013 60 100606060 N/A60 N/A6 (13.0) 100 60 N/ADeutsch <strong>DT</strong> <strong>Series</strong> of environmentally-sealed, connectors aredesigned specifically for cable to cable applications on the engineor 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 <strong>DT</strong> <strong>Series</strong> general purpose connectors will providethe reliability and performance at the lowest cost.Thermoplastic (-55 0 C to + 125 0 C rated) housings and siliconeseals are used to allow the connector to withstand conditionsof extreme temperature and moisture. The connector may beemployed with either solid-copper crimp type contacts for criticalcircuits or budget-minded stamped and formed contacts. Ineither selection, the spring action is designed in the socket andshrouded by a stainless steel hood that provides closed entry forpositive axial alignment during mating, and eliminates probedamage from occurring. Contact insertion and withdrawal requireno special tools and are retained in locked position by dielecticfingers, molded as an integral part of the housing. Secondarylocks are assembled at the mating interfaces. If by chance thesecondary locks are not properly seated during assembly, theywill be pressed into locked position during the mating of theconnector.Deutsch developed the <strong>DT</strong>HD <strong>Series</strong> for those applications requiring acomplete, environmentally sealed, single power circuit termination.<strong>DT</strong>HD plugs and receptacles can be permanently assembled withthermoplastic end caps that prevent removal of the silicone wireseal grommets. Designed for diesel engine, electronic fuel injectors,automatic transmissions, ABS brakes and other applications thatinvolve fuel and oil exposure. These end caps provide the additionalreliability required for critical wiring circuits.Submersion:Properly wired and mated connection will withstand immersion underthree feet of water without loss of electronic qualities or leakage.Fluid Resistance:Connectors show no damage when exposed to most fluids used inindustrial applications.Vibration:No unlocking or unmating and exhibits no mechanical or physicaldamage after sinusoidal vibration levels of 20 G’s at 10 to 2000Hz in each of the three mutually perpendicular planes. No electricaldiscontinuities longer than 1 microsecond.Temperature:Operative at temperatures from -55 0 C to +125 0 C.
