Application report - Forklifts

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 truckprecisely even under extreme conditions.

Solution:

The used differential hall-effect sensors of the FC series send 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 (IP67 / IP69K).
