Testing the second prototype iteration of the ultra-quiet RZ32 tubular motor by Dendo Systems. The scraping sound mid-way is the bottom rail scraping against the window handle. It's normally a small sound, but even this is much more audible than the motor itself!
Seen here is the internal rechargeable battery version. DC also available. Compatible with the Smart Control Module for easy smart home integration via ZigBee or Matter over Thread.
