Deutsch HD30 Series
A heavy duty, environmentally sealed, multi-pin circular
connector, featuring quick connect-disconnect bayonet
coupling, single hole bulkhead mounting, silicone seals, with
a rear insertion/rear removal contact system.
The Deutsch HD30 Series connector, was developed to meet
the needs of the heavy duty equipment and transportation
industries for rugged, multi-pin, sealed connector systems.
Deutsch HDP20 Series
Designed specifically for the truck, bus and off-highway industry,
the HDP20 Series is a heavy duty rated, environmentally sealed,
composite shell, multi-pin connector. The plug features a quick
connect-disconnect bayonet style coupling and the receptacle
is designed for single hole mounting. Thus reducing assembly
line time and installation costs.

shoulder of the contact, preventing accidental dislodging.
Although securely locked in place, these contacts can be
quickly and easily removed by the use of an inexpensive, non-
conductive removal tool.
Corrosion Proof Plastic Shell HDP20 Series Provide
a Cost Effective Alternative
Deutsch plastic shell HDP20 Series provide cost effectiveness
with heavy duty terminations for the truck, bus & off-
highway industries. Other features include: silicone wire and
interfacial seals, visual indication of lock and mated position.
Corrosion proof plastic shells and use of low cost stamped
and formed contacts provides a cost effective solution for your
application.
The HDP20 uses a bayonet coupling system to provide a
vibration resistant locking mechanism. This shell provides
a multiple keying system that positively prevents mismating
and makes plug and receptacle coupling quick and easy.
Receptacles mount with a single hole using a “flat” to prevent
the connector from rotating.
Rugged Metal Shell HD30 Series Withstands Years of
Abuse
Deutsch HD30 Series features a lightweight, yet compact and
rugged metal shell to protect contacts and sealing grommets.
This shell provides a multiple keying system that positively
prevents mismating and makes plug and receptacle coupling
quick and easy.
The HD30 Series uses a bayonet coupling system that provides
a positive vibration resistant locking mechanism with visual
indication of proper mate and lock. This quick disconnect
system requires only a quarter turn to operate.
Easy installation to structure is provided by a single one-hole
mounting system using a “flat” to prevent the connector from
rotating during assembly or service.
The HD/HDP Series
Decreases Costs and UP-Grades Performance
The Deutsch HD/HDP Series was developed to provide a
solution to today’s system problems found in the heavy duty
trucking, equipment and transportation industries. The HD/
HDP is a cylindrical, multi-pin, sealed device utilizing crimp
type contacts that are quickly and easily inserted or removed.
Use of the HD/HDP Series eliminates several other common
connector problems.
Problems associated with assembly and network time,
operational breakdowns requiring costly repairs and lengthy
out of service time in the field have all been reduced and/or
eliminated by the judicious application of the HD/HDP Series.
Deutsch HD/HDP Series provide the widest selection of
interconnections for critical circuits requiring heavy-duty
environmental terminations. Together, the HD and HDP offer
common layouts, common tooling, the same adaptability to
backshells and both meet the performance standards for heavy
duty applications. So whether you are looking for rugged HD
metal shells or cost effective HDP plastic shells, Deutsch offers
the best product for your applications while holding the line
on hidden inventory and assembly costs.
Some of the benefits of the Deutsch HD/HDP
Series include:
• Quick, fool-proof assembly, decreasing time on the assembly
line and eliminating miswiring.
• Simple and easy to rework, decreasing down time and
increasing profits to the operator.
• Sealed against moisture and contaminants, eliminating open
wiring system.
• Operation under severe shock and vibration, reducing break
down and out of commission loss due to rugged operating
conditions.
• Performance over a wide temperature range (-55
0
C to
+125
0
C) meaning continuous operation in all environments,
from arctic to desert conditions.
• Human factors engineered to assure that assembly and
rework can be reliably handled by unskilled personnel.

Electrical Connectors:
Critical to System Reliability and Maintainability
Recent studies indicate that electrical system failures are a
common and constant source of equipment malfunction.
A major area of electrical system failure is in electrical
interconnections. Typical problems include loose and miswired
terminals, corrosion, and contamination of terminals. Coupled
with these problems, the impact of sophisticated safety
devices, automated check-out systems, and other increased
use of electronics, call for a re-examination of traditional
termination techniques. To the operator, termination failures
mean excessive down time and maintenance costs. This adds
up to slipped production schedules, cost over-runs and user
problems. The end result: decreased profits and a loss of
share of the market. In today’s competitive arena, improved
electrical connectors can make the difference between a
growing, profitable operation or a losing one.

SEAL
Sealed Against Moisture and Contaminants
Unlike terminal strips, binding posts and other open-wiring
systems, the Deutsch HD/HDP Series is a completely sealed
unit. The rear of the connector features an integral grommet
wire seal that automatically seals each contact as it is locked
into place during installation. There is no extra hardware to
fasten or tighten or potting operation to achieve this seal.
Fabricated from tear resistant, high temperature silicone,
this rear grommet protects the contact from moisture, sand,
dust, lubricating oils, road salt, hydraulic fluid, grease, mud
and other contaminants encountered in heavy duty use. The
elimination of open-wiring systems does away with such
common hazards as short circuits due to metallic objects
across the terminals. This is especially important during
loading or refueling operation when a spark could cause a
serious explosion. Closed wiring also protects maintenance
personnel against accidental shock, yet can be easily checked
for circuit continuity.
Contact Retention Decreases Installation Costs and
Increases Reliability
The HD/HDP Series uses crimp type, solid copper alloy contacts
for damage proof performance and stamped & formed copper
alloy contacts for cost effectiveness. Each style has the ability
to carry continuous high operating current loads without
overheating. The contacts or terminals are crimp terminated
using automatic tooling for production and inexpensive readily
available hand tools for field maintenance. After crimping,
these contacts are easily installed by simply pushing the
contact into place by hand. Contacts are positively secured
by use of “fingers” in the connector which lock behind the
