The BJ type motor is designed for roller shutter motorisation.
It has an overload mechanism, thanks to which the motor stops, as it recognises resistance.
The motor has a thee-level overload sensitivity adjustment scale.
The motor does not have limit switches, so the components blocking the roller shutter in its upper and lower limit positions are required. That is how the motor will stop by using its overload mechanism.
The motors can be connected in parallel, which allows you to control a few motors with one switch, with no need to use any additional systems.
