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 (0.5mm2 to 1.5mm2). 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 (-550 C to +1250 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 (-550 C to + 1250 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.
