Inductive System for Wireless Sensors Extends Transmission Distances

The Wireless Inductive System 2 (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 to 7 mm compared to the WIS 1 with a maximum of 1.5 W and 0 to 5 mm. 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.
