An alternative solution is to place a angular sensor in the joint between the front and rear, this is practical in vehicle-trailer combinations where there are no hydraulic cylinders connecting the two. In such case can an angular sensor with separate sensor housing and magnet be a suitable option, for example ACW4. The magnet can be mounted on the trailer and sensor housing on the vehicle, and as the sensor housing and magnet are not mechanically connected can the trailer be disconnected without additional steps to disconnect the sensor. Angular sensors can also be used as feedback-sensor on the trailer bogie, to ensure that the trailer co-tracks the vehicle.
Angular sensors offer a compact, low-cost and flexible solution, the downside is that it’s not as robust as cylinder sensors. Mounting and enclosures of the sensor need to be well designed to protect the sensor from external environmental and mechanical stresses.
