Wireless Sensor Interface Goes The Distance

The second-generation Wireless Inductive System 2 (WIS 2) for wireless connection of sensors to moving machine parts 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 up to 12W 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 eight-channel design, a streamlined two-channel variant is 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 eight-way connector box with an IP67 degree of protection that can be installed up to 20m away from the transmitter.
