Task:
The speed and direction of rotation of the two separate power heads in the drive axle of a three-phase forklift truck are to be measured by the control system. The same sensor type is to be used for the fine control of the lift drive. A stable, high-precision sensor is required to operate the forklift truck precisely even under extreme conditions.

Solution:
The differential hall-effect sensor puts out two frequency signals with a phase shift of exactly 90° with low jitter.

As a result, high accuracy can be achieved and the vehicle can be controlled precisely in any situation. The sensor is media and temperature resistant (-40 to +160°C) and waterproof (IP69). It is ideally suited for hydrostatic drives due to its resistance to pressures of up to 220 psi. Sensors for higher pressure to 7250 psi are available.
