| Modular terminals are available with many different types of connection. It is not the rule that a manufacturer of modular terminals supplies every possible connection system in their range. However, manufacturers who can supply "all connection systems" from their own products clearly have an advantage. Such manufacturers can cover the most diverse requirements in the global marketplaces for industrial and process automation as well as transport engineering. Weidmüller covers the complete range. |

Terminal
Blocks for 1000 VDC Applications - Insulated lines react completely
differently to partial discharge tests with AC voltage than to partial discharge
tests with DC voltage. It is not possible to draw conclusions as to whether a
terminal block is suitable or not for 1000 VDC applications simply by
considering the thickness of the insulation, its dimensions or other physical
attributes in isolation.

Certification
of Termination Tools- Regular quality checks of
Weidmüller processing tools and the assemblies made with
them guarantee optimum safety. In order to keep it that
way and to prevent possible machine stoppages during
production, regular maintenance and precise tool
calibration is simply indispensable. In order to receive a
certified tool, customers have the option of either
returning an existing Weidmüller tool for re-certification, or
of purchasing a certified Weidmüller tool on submitting a
new order. Simply contact
Weidmüller to get further information.
Cutting
Tools - A large number of cables and conductors in many
different types and designs are used to connect electrical and electronic
components. The cables and wires must be accurately prepared for the various
types of connection. The quality of the cutting process is therefore of critical
importance. Mechanical efficiency together with the special cutting pattern
reduces the manual force required to a minimum.
Stripping
Tools
- After a conductor has been cut it is then prepared for the
next step or for crimping. For this purpose, a specific length of the conductor
insulation has to be removed, while preventing damage to the conductor. The
length of the conductor insulation to be removed depends on the terminal
clamping point or the crimp to be processed. Professional stripping tools
guarantee perfect results due to precise adjustment of the tool to the
corresponding insulation and the conductor cross-section. Precision tools by
Weidmüller guarantee that the user will always obtain consistent, reliable
stripping results. “Stripping” means the cutting and removal of the
insulation. The methods required to perform this task correctly are detailed in
this download.
Crimping
Tools - After stripping, appropriate contacts
or wire end ferrules can be crimped to the cable end. Crimping produces a
reliable connection between conductor and contact, and has more or less
completely replaced soldering. Crimping describes the production of a uniform,
nondetachable connection between conductor and connecting element. This should
be achieved exclusively by the use of a high-quality precision tool. The result
is a safe, reliable connection in both electrical and mechanical terms.

What to look for in a Printed Circuit Board Connector - Bill Carson - RoHS compliance is the talk of the industry, but what does this mean for companies? Added costs, redesign issues? It is a chance to question everything in the process of choosing printed circuit board connectors. The mission of the connector system is to make a foolproof, reliable electrical connection with little or no distortion, all while being exposed to vibration, contamination or extremes in temperature. In order to do this successfully, a number of factors must be considered, based on the application. What type of clamping system should be used? What are the material requirements? Are there environmental factors to consider? Is board density a factor? What manufacturing process will be used? What is the real cost of the connector? Will the end product meet the EU directive RoHS (Restriction of Hazardous Substances)? With so many PCB connector options available today, many customers simply think in terms of cost and delivery, but there is so much going on with those little connectors on the PCB board.

Cable
Termination Techniques - There are a variety of termination methods for
cable. The termination method utilized depends basically on the system
installed, type of cable used and type of connector. Using the proper
termination method allows for good mechanical and electrical integrity. No
matter what type of termination you will be performing, the most important thing
is to use the proper tools and materials for the type of termination. For
example, a crimp using pliers will work, but using a crimp tool and the proper
die designed for your type of cable and connector is better. Using the proper
solder type and the right temperature for solder type connections will ensure a
lasting connection. We will review four basic termination techniques. This is
just to provide some general guidelines. The termination method may vary
somewhat based on system requirements and connector manufacture design methods. From West Penn Wire http://www.westpenn-cdt.com

Basic Electrical Training Course - This excellent 14 page pdf from Deutsch Advanced Interconnect is focused on the technology around connectors. This article is not an attempt at a basic course in electronics - rather, it is a course that will help you understand the electrical requirements that pertain to connectors. It’s pretty basic stuff - we promise not to get much heavier than Ohm’s Law and a few buzzwords. You’ll also be introduced to wire and cable so you’ll have a better understanding about connector applications.

Corrosion
Resistance of Electric Wire Terminals Used in Harsh Industrial Environments
- Industry reports indicate that 50
to 60 percent of electrical downtime has been
traced to open or intermittent connections.1 Harsh industrial environments
increase the risk of corrosion and chemical attack on metals used
in wire terminal connections, potentially affecting electrical reliability.
Engineers designing industrial control products must apply
sound judgment in material selection and wire clamp
design along with rigorous test methods to ensure
reliable long term performance under harsh field conditions.
Accelerated corrosion testing is an important tool for use
in product designs such as wire terminal systems.
Test methods such as salt spray testing have traditionally
been used to evaluate corrosion resistance but can seldom be correlated
to actual field performance. Other methods using corrosive gas mixtures
have been developed to better correlate with field conditions. This
paper studies corrosion resistance of wire terminal connections made from
a variety of materials and protective platings and coatings. Accelerated test
methods using both salt spray and corrosive gas mixtures were applied. The
results show that each base metal and protective coating has it's strengths
and weaknesses. Steel with zinc-trivalent chromate protective coatings
performed well but vary significantly depending on the thickness of
zinc, type of chromate, and use of sealers. Nickel-plated brass performed
well except in environments with high concentrations of
ammonia. Stainless steel provided the best and most
universal corrosion resistance. The information
presented in this paper can be applied to make more knowledgeable
product selection decisions that will help ensure long term reliability
of electrical connections used in industrial control applications - From

A
Systems Approach to Functional Terminal Block Design - Consider where
signals are processed in measurement, conversion and regulation systems -
Carsten Luckheide - Ideally, functional terminal blocks should be easy to use,
provide secure connections and make it simple to bridge terminals, whether or
not they are adjacent. By taking a systems approach to functional terminal block
design, though, a single block can be adapted to different connection
requirements - from plantservices.com
