EtherCAT 高精度激光测距传感器确立了新标准

PNBC 系列的精确测距传感器树立了一个新的里程碑：位移测量传感器能够精确测量极小的差异，即使从很远的距离测量也是如此。激光传感器的光学系统能够实现可重现的测量结果。它们可以进行非接触测量，不受物体表面特性、形状和颜色的影响。因此，测量值不受影响。除了经过验证的 TCP/IP 接口外，现在还提供 EtherCAT 工业以太网接口，用于实时采集和进一步处理测量数据。无论是测量厚度、测量位移量还是测量距离，PNBC 激光位移传感器都是同类产品中的最佳产品。

PNBC 系列激光测距传感器在测量时使用高分辨率的 CMOS 阵列。使用非常先进的角度测量分析技术可以计算出与测量物体的距离，精度达到微米级。激光测距传感器基于三角测量原理，非常适合距离达 1,000 mm 的高精度测量。

Real-Time Data Communication down to the Fieldbus Level

There are various options for industrial data communication. With our range of innovative industrial Ethernet products, we were the first sensor manufacturer to make it possible to send process and parameter data from sensors and actuators directly to the controller. This guarantees continuous data communication in real-time right on up to the fieldbus level. With the PNBC series, the data is transmitted via communication channels and connections via Ethernet. Laser triangulation sensors offer advantages with the EtherCAT industrial Ethernet interface. Especially in fast processes and when networking multiple devices.

EtherCAT for Precise and Fast Applications

Thanks to the direct data output, the measured values are available in real time. The web server integrated in the sensors enables worldwide access to the device’s own website for the respective product. Process and parameter data can be accessed quickly and easily without additional software.

High-Precision Triangulation Sensors for All Challenges

Measuring the Unwinding and Winding of Films on Rollers

Coated, high-gloss films are used to manufacture batteries. In order to detect their level on winding devices, high-precision laser distance sensors measure the exact distance – regardless of shape, color or surface. In this way, it is precisely determined on the unwinder how much material can still be unwound; on the rewinder, it is determined how much space there is available for material on the roller. The film is wound or unwound at a speed of up to 10 m/s for coating. The measured values are output via Ethernet interface and further processed.

Tilt Protection for Maintenance Vehicles for Overhead Lines

Overhead lines of rail networks require regular maintenance. Special maintenance vehicles with lifting platforms are used for this purpose. To prevent excessive tilting or unintentional tipping of the vehicle when the work platform is extended, four high-precision laser distance sensors per carriage measure the exact distance from the vehicle to the rail head with precision in the low micrometer range. Equipped with laser class 2, the sensors detect the distance to the track from a protective housing. If a defined tolerance value is exceeded, it is no longer possible to extend the lifting platform.
