Sensor technology specialist Pepperl+Fuchs is breaking new ground with ultrasonic sensor technology for CAN-based applications in mobile machines: For the first time, manufacturers of construction machinery and off-road vehicles can use E1-approved ultrasonic sensors with an integrated CAN interface in their mobile machines. The costly and time-consuming integration of additional CAN interfaces is now a thing of the past.

The extension of the proven L2 product family from Pepperl+Fuchs allows configuration of all sensor functions via CAN on a PLC, a PC or via a USB-CAN converter. Interference target suppression and adjustable sound lobe width enable optimal adaptation to the application. Protruding machine parts that could cause interference can be easily masked out, while the sound lobe can be adjusted without loss of scanning range. Autonomous synchronization also makes it possible to operate multiple ultrasonic sensors in close proximity to each other.

Once parameterized, the new L2-CAN sensors demonstrate the strength of industrial ultrasonic technology: regardless of material, surface structure and color, distances are measured reliably – even under the most difficult environmental conditions. Protection class IP68, high EMC resistance and an extended temperature range from -40 °C to +85 °C testify to the robustness of the sensors. To simplify wiring of the devices on mobile machines, connections such as AMP and DEUTSCH are available in addition to variants with the round connectors commonly used in industrial automation.
