Reliable speed monitoring AGV
Reliable speed control is essential for Automated Guided Vehicles (AGVs). Depending on the speed, the protective fields of the AGV are extended. In the event of a fault inside the protective field, the AGV must safely reduce speed. The speed can be reliably determined using an incremental encoder. The encoder is mounted directly on the wheel and the values determined are compared with the controller. Compact designs, such as the 36 mm housing, allow installation in confined spaces. Wachendorff also offers redundant incremental encoders with independent optical and magnetic sensor systems.

Exact positioning of the fork
Accurate positioning of the system is essential. An example of this is the accurate determination of the height of a forklift truck for racking operation. By using a customised, high-precision draw wire system SZG140, the measurement can be seamlessly integrated into the rail We offer draw-wire systems with a cable length of up to 40 m. It is possible to choose between incremental or absolute encoders.
Important features:
- Measuring lengths up to 5.0 m
- Compact housing
- High resolution
- Incremental and absolute versions
- Quick mounting
- High precision mechanics with high linearity

Detection of the steering angle of an AGV
Accurate measurement of the steering angle is important for precise steering of the AGV. For this purpose, the WDGA 36E CANopen absolute encoder is mounted directly on the steering drive and can therefore measure and monitor the steering angle of the vehicle. The ability to monitor the steering angle can increase the safety of the vehicles. The encoders are also available with various absolute interfaces for optimum compatibility.
