WAGO, the Global Leader in Spring Pressure Termination Technology
As the innovators of the world renowned CAGE CLAMP®concept, WAGO has been the world market leader for more than a half century in the design and manufacture of termination systems incorporating screw-less, spring pressure, wire termination technology. Today, WAGO offers an unrivalled range of advanced products including PCB mount terminal blocks and connectors, chassis mount terminal blocks, DIN rail mount terminal blocks, relay modules, signal conditioners, controller interface modules, power supplies, outlet boxes, push-wire connectors, and the WAGO I/O System - a complete line of programmable controllers (IEC 61131-3 compliant) and fieldbus couplers for over 16 networks (including Ethernet, DeviceNet, and Profibus) with over 100+ modular (1,2,4, or 8 channel) I/O signal interfaces to meet all your application requirements.

CAGE CLAMP®- an Industry Changing Concept
1951 marked the beginning of WAGO's success story. In this year, the first terminal block with spring pressure termination technology was born. This innovation led to the first push-wire connection in 1968, and then in 1977 to the industry changing termination technology known as CAGE CLAMP®.

In contrast to traditional screw-type termination technologies, WAGO's screw-less, spring pressure termination technologies can reduce wiring by up to 75%. Even more important is the fact that, because the clamping force automatically adjusts to the wire size, it provides a highly reliable, maintenance-free contact that is virtually independent of operator skill. The end result is a secure, vibration proof, temperature cycling resistant, and cost saving connection - every time.

10 Years of the WAGO-I/O-SYSTEM
In 1995, at the ISA Expo, WAGO Corporation introduced a revolutionary concept in fieldbus I/O technology - the WAGO-I/O-SYSTEM. As the first granular (as little as 1 channel per module), micro-modular (12 mm wide package), and fieldbus independent (supporting DeviceNet, Profibus, and Modbus) I/O system in the market, WAGO set the standard for all others to follow. And, although very little has changed in it's form factor over the last 10 years, the WAGO-I/O-SYSTEM has grown in networks supported, signal types supported, and programmability. Today, it supports over 16 network protocols (including the latest trends such as EtherNet/IP and FireWire), over 200 different I/O modules (analog, digital, and special functions), full PLC programmability and embedded PC technology, highest granularity (8 channels of digital in or out in just 12 mm), pluggable connectors, and more.

Proven Technology Over Time
The underlying concepts of WAGO's products, services, and technologies are safety and reliability. Couple over 8 billion CAGE CLAMP® installed in the field today with a high awareness for quality control, and you get the safety and reliability their customers have come to expect from us. As an ISO 9001:2000 certified company, they stand ready to support your applications with the highest quality products at the lowest installed cost.

The Result of WAGO's Experience
As the inventor of CAGE CLAMP®, WAGO offers more than 25 years of experience with this technology. This results in the most extensive line of spring pressure termination technology products, more than 12,000 parts numbers, and the right spring pressure technology for the task at hand.
