For more than 40 years, WAGO terminal blocks and connectors
have incorporated the company's unique spring pressure clamping
technology have been used in electrical and electronic install-
ations worldwide. They have performed successfully under all
types of operating conditions in a wide variety of industrial
and other applications including processing, petro-chemical,
automotive, shipbuilding, railways, environmental technology,
lighting and building services.
Although WAGO's spring clamping system reduces wiring time
substantially compared to screw-type methods, the most important
benefit it offers is that because the clamping force adjusts
automatically to wire size, it provides a reliable contact virtually
independent of operator skill. The end result is a secure, vibration-
proof, maintenance-free clamping connection - every time.
This overriding concern with safety has always been central to
WAGO's thinking. It led in 1951 to the introduction of the PUSHWIRE
SPRING CLAMPING (A) concept - a major breakthrough in
termination technology - and in 1977 to the launch of the
CAGE CLAMP (B) connection.

Two Clamping Systems
WAGO's pioneering technique of clamping wires by spring pressure instead of
by screws provides users with a number of outstandting benefits. To begin
with, it cuts wiring time dramatically - typically, by up to 50 % compared
to screw type systems. Independent data shows clearly the time savings
which WAGO's PUSHWIRE and CAGE CLAMP connections can provide (see
diagrams A & B). In the case of CAGE CLAMP, even when power screwdrivers
are used, it still offers a significant advantage (KLOCKNER-MOELLER
study VER 21-668).
WAGO terminal blocks and connectors are designed to adjust automatically
to the individual wire size being inserted, thus providing the optimum
clamping force required in each case. This ensures a safe, reliable connection
every time - virtually regardless of the skills of the installer. WAGO
products also provide high resistance to corrosion, vibration and thermal
stress, even under the most rigorous operating conditions.
PUSHWIRE connections are suitable for
applications where solid wire is used
exclusively - for example in lighting,
building installations, telecommunications
and security. PUSHWIRE is capable of
handling solid copper conductors from
0.5 mm2/AWG 20 to 4 mm2/AWG 10.
CAGE CLAMP is suitable for direct connection of solid,
stranded or fine stranded machine tool wire, as well as,
with crimped ferrules, pin terminals or tip bonded wire
from 0.08 mm2/AWG 30 to 35 mm2/AWG 2. It is used
extensively in electrical and electronic applications
in a wide range of industries.
In summary, the easy to use, maintenance-free and gas-tight clamping
systems incorporated in WAGO's unique range of terminal blocks and
connectors, provide a combination of reliability and cost effectiveness
which other manufacturers cannot match. It is precisely these qualities
which give WAGO its major competitive advantage now and for the future.
WAGO I/O System
Fieldbus Independent BUS Terminal Blocks
Complex production equipment, such as that used in the automated
manufacturing industries uses large numbers of sensors and actuators.
Use of a fieldbus system and distributed control can considerably
reduce costs.
Fieldbus nodes (the fieldbus connection + 1/0 points) are of a special
importance in this context. If these are properly designed much of
the cost can be minimized.
Optimum design of a Fieldbus Node
The following requirements must be met in order
to design an economic fieldbus node:
Best possible modularity-
.......... - 2 Channel for standard l/Os.
.......... - Single channel for special functions.
Combination of digital and analog l/Os including various
...... voltage, power and instrumentation signal requirements
...... within a node.
Sensors and actuators may be wired independently
...... of the fieldbus.
Fast coupling to the chosen fieldbus.
Quick and clear marking facility .
Easy handling with few additional accessories.
Fast and easy wiring with high operational reliability.
Using the WAGO l/O-SYSTEM it is now possible:
To proceed with external wiring of the 1/0 modules without knowledge of
the fieldbus system to be used simple snap-fit mounting of the respective
fieldbus coupler to the wired modules when fieldbus system is known.
This gives:
Inventory reduction and greater availability of modules for many different
fieldbus systems, by adaptation of all modules with a single bus coupler
chosen for that system.
