Material Handling Applications

Task: The speeds and directions of rotation of the two separated power heads in the driving axle of a three-phase forklift truck are to be measured and transferred to the control system. Furthermore the same sensor type is to be used for the fine control of the lifting drive. A stable, high-precision sensor is required to operate the forklift truck precisely even under extreme conditions. Solution: The differential hall-effect sensor in use sends signals to two frequency outputs with a phase shift of exactly 90° at the lowest jitter. As a result high evaluation accuracy can be achieved and the vehicle can be controlled precisely in any situation. The sensor is media-resistant, temperature-resistant (40°C...+160°C) and waterproof (IP69). It is ideally suited for hydrostatic drives due to its resistance to pressures of up to 15 bar. An ideal sensor for Linde, Still and OM Pimespo within the Linde division of “ Material-Handling”.
