About ITT Cannon
ITT Corporation is a diversified leading manufacturer of highly
engineered critical components and customized technology
solutions for industrial end-markets in energy infrastructure,
electronics, aerospace and transportation. Building on its
heritage of innovation, ITT partners with its customers to deliver
enduring solutions to the key industries that underpin our
modern way of life. Founded in 1920, ITT is headquartered in
White Plains, N.Y., with employees in more than 35 countries
and sales from a total of 125 countries, which generated 2015
revenues of $2.5 billion.
our manufacturing strength and our advanced manufacturing
facilities allows ITT to offer products at market driven prices.
Our capabilities, especially in robotics, computerized precision
tooling, Kaizen Project Management, Six Sigma tools, and
testing, give ITT the most optimized global manufacturing
footprint in the interconnect industry.
The Custom Difference
As the industry leader in harsh environment interconnect
applications, ITT’s world class engineering teams will work
directly with our customers to design and develop cost effective
solutions for their applications. In many cases we may modify
one of our standard designs to ensure a highly reliable solution
where timing is critical. When custom connectors are required,
we collaborate with clients and partners with a goal to design
the most reliable, cost-effective solution possible. As professional
consultants, our Engineering teams will provide a thorough
systems and mechanical analysis of any proposed solution.
These analyses provide our customers with sophisticated
electrical signal and mechanical characterizations to determine
the best solution for their application.
Our connector portfolio remains the most extensive in the
industry, offering a reliable and cost effective range of
interconnect solutions with the brands of Cannon, VEAM and
BIW Connector Systems. Continuous investment in technology
and research & development have enabled ITT to provide new,
innovative products and solutions to markets including:
•Commercial Aviation
•Defense
•Oil & Gas
•Transportation & Industrial
•Medical
•Space Exploration
When you specify a Cannon, VEAM or BIW Connector Systems
connector, you can rely on products that are designed,
developed, and manufactured to the highest quality and
reliability standards. This tradition of excellence is based on ITT’s
corporate culture of operating its businesses under the principles
of Six Sigma. At ITT, Six Sigma is not just a quality philosophy
but a complete corporate culture that drives the entire business.
Our Value Based Management and Value Based Product
Development systems are two cornerstones that allow for
the development of both leadership and product engineering
principles, ensuring our industry leading products are developed
to the accepted market driven lead times. These principles have
allowed ITT to become the market leader in all of our business
portfolios.
RoHS Compliance Information
ITT has implemented a strict parts control plan for all ITT
electronics plants worldwide that allows the Cannon, VEAM,
and BIW Connector Systems product portfolios to meet the
requirements of the European Union Directive 2002/95/EC
better known as the Reduction of Hazardous Substances
initiative. As appropriate, specific Cannon, VEAM, and BIW
Connector Systems products may be ordered with an R
prefix number which insures our customers will receive RoHS
compliant parts for their commercial electronics applications
and equipment. Since most RoHS hazardous substances center
around specific metal plating and lead solder coatings, ITT’s
products for RoHS compliance are available in the following
plating finishes: electroless nickel, stainless steel, anodize over
aluminum and gold plating. It should be noted that gold plating
would be recommended as the replacement for tin-lead solder
when ordering board mount connectors.
Six Sigma Manufacturing
ITT Cannon operates manufacturing facilities in the United
States, Germany, Italy, Mexico, China and Japan, all of which
have particular product area strengths allowing ITT to offer a
truly global footprint to our customers. Our facilities are world
class and accommodate full vertical integration utilizing the
latest manufacturing technologies including: automated and
robotic machining centers, Super Market manufacturing cells,
Kanban pull systems, and automated electrical, mechanical,
and optical test and inspection equipment. The combination of

Product Safety
no solder blobs, loose strands, conducting lubricants, swarf, or
any other undesired conducting particles. Circuit resistance and
continuity check should be made to make certain that there are no
high resistance joints or spurious conducting paths. Always use the
correct application tools as specified in the Data Sheet/Catalog. Do
not permit untrained personnel to wire, assemble or tamper with
connectors. For operation voltage please see appropriate national
regulations.
1. Material Content and Physical Form
Electrical connectors do not usually contain hazardous materials.
They contain conducting and non-conducting materials and can
be divided into two groups.
a) Printed circuit types and low cost audio types which employ
all plastic insulators and casings.
b) Rugged, Fire Barrier and High Reliability types with metal
casings and either natural rubber, synthetic rubber, plastic or
glass insulating materials. Contact materials vary with type of
connector and also application and are usually manufactured
from either: Copper, copper alloys, nickel, alumel, chromel or
steel. In special applications, other alloys may be specified.
Important General Information
(i) Air and creepage paths/Operating voltage. The admissible
operating voltages depend on the individual applications and the
valid national and other applicable safety regulations. For this
reason the air and creepage path data are only reference values.
Observe reduction of air and creepage paths due to PC board
and/or harnessing.
(ii) Temperature
All information given are temperature limits. The operation
temperature depends on the individual application.
(iii) Other important information
ITT Cannon continuously endeavors to improve their products.
Therefore, Cannon products may deviate from the description,
technical data and shape as shown in this catalog and data
sheets.
2. Fire Characteristics And Electric Shock Hazard
There is no fire hazard when the connector is correctly wired and
used within the specified parameters. Incorrect wiring or assembly
of the connector or careless use of metal tools or conductive fluids,
or transit damage to any of the component parts may cause electric
shock or burns. Live circuits must not be broken by separating
mated connectors as this may cause arcing, ionization and burning.
Heat dissipation is greater at maximum resistance in a circuit.
Hot spots may occur when resistance is raised locally by damage,
e.g. cracked or deformed contacts, broken strands of wire. Local
overheating may also result from the use of the incorrect application
tools or from poor quality soldering or slack screw terminals.
Overheating may occur if the ratings in the product Data Sheet/
Catalog are exceeded and can cause breakdown of insulation and
hence electric shock. If heating is allowed to continue it intensifies
by further increasing the local resistance through loss of temper of
spring contacts, formation of oxide film on contacts and wires and
leakage currents through carbonization of insulation and tracking
paths. Fire can then result in the presence of combustible materials
and this may release noxious fumes. Overheating may not be visually
apparent. Burns may result from touching overheated components.
ITT Cannon, is a division of ITT Corporation who manufactures

3. Handling
Care must be taken to avoid damage to any component parts of
electrical connectors during installation and use. Although there are
normally no sharp edges, care must be taken when handling certain
components to avoid injury to fingers. Electrical connectors may
be damaged in transit to the customers, and damage may result in
creation of hazards. Products should therefore be examined prior to
installation/use and rejected if found to be damaged.
This publication is not to be construed as an offer. It is intended
merely as an invitation to make an offer. By this publication, ITT
Cannon does not assume responsibility or any liability for any patent
infringements or other rights of third parties which may result from
its use.

fumes.
5. Application
This document does not contain technical data whose export is
restricted by the Arms Export Control Act (Title 22, U.S.C., App
2401 et. Seq.)
Connectors with exposed contacts should not be selected for use
on the current supply side of an electrical circuit, because an electric
shock could result from touching exposed contacts on an unmated
connector. Voltages in excess of 30 V ac or 42.5 V dc are potentially
hazardous and care should be taken to ensure that such voltages
cannot be transmitted in any way to exposed metal parts of the
connector body. The connector and wiring should be checked,
before making live, to have no damage to metal parts or insulators,
