Wireless Inductive System 2 for Wireless Sensor Connection

New Generation with Greater Power and Longer Transmission Distances

Pepperl+Fuchs: The new WIS 2 (Wireless Inductive System 2) is the ideal way for Pepperl+Fuchs to round off its portfolio for the wireless connection of sensors to moving machine parts with a higher-performance system.

The WIS 2 is used both for signal transmission and for supplying power to the sensors connected to the secondary side, making wear-prone trailing cables and slip rings redundant. The WIS 2 supports ratings of up to 12 W over transmission distances of 0...7 mm compared to the WIS 1 with a maximum of 1.5 W and 0...5 mm, which has been available for years. In addition to the 8-channel design, a streamlined 2-channel variant is now also available for small applications with up to two sensors.

All system variants use a primary and a secondary transmitter, either for two or for eight channels. They come in size M30 in a cylindrical design and fitted with 30 cm cables and M12 connectors as standard. Since the transmitters are not paired, the secondary transmitters are freely interchangeable. As a result, for example, any number of different tool carriers can easily communicate via the same system. Inductive, capacitive, optical or ultrasound models with binary switching output and standard 3-wire connection technology are suitable as sensors. Whereas the 2-channel system uses a space-saving Y-splitter, the 8-channel system has an 8-way connector box with an IP67 degree of protection that can be installed up to 20 m away from the transmitter. Pepperl+Fuchs provides a wide selection of cable lengths and connectors for every application.

The WIS 2 has numerous potential applications in rotary tables, presses and change tools, for object detection on workpiece carriers, on rotation tools, robot gripper arms and all similar devices.

Pepperl+Fuchs is one of the world’s leading providers of industrial sensors and explosion protection. Based on an intense dialogue with our customers for more than 70 years we continue to develop new components and solutions, which support their applications the best way possible. For the landmark topic Industrie 4.0 (Industrial Internet of Things) we develop innovative technologies that pave the way to the digital networked production and to data transfer across all hierarchy levels – even beyond companies’ boundaries.

Industrial sensors: focus on the market
Market-specific solutions dominate an extensive portfolio of industrial sensors that covers all applications the market requires from today’s automation technology. From the inductive and capacitive to the photoelectrical and highly precise ultrasonic sensors, identification systems and many more Pepperl+Fuchs offers all current operating principles in a broad variety.
Sensorik4.0® provides sensor technology for Industrie 4.0. Our technologies enable sensors without difficulty to communicate horizontally within the production process and to exchange data vertically – even into higher-level information systems such as MES or ERP.

Process interfaces: secure applications
Components and technologies for use in hazardous areas are designed to fit the most specific requirements in the industries we serve. They guarantee maximum availability at maximum safety. Isolated barriers, signal isolators, remote I/O or fieldbus systems, HMIs and many other technologies offer solutions for a wide range of applications including certified packaged solutions and all types of explosion protection.
Ex-Protection4.0 brings digital networked Industrie 4.0-production structures to process industries. With concept studies like Ethernet for Process Automation integrated communication throughout all levels of an automation system via Ethernet becomes feasible – for the first time ever even down to the filed level.
