TUYA 400mm Electric Chain Window Actuator - Automatic Sliding Opener Switch

400mm electric chain actuator for home sliding windows with TUYA compatibility. The chain bends in a single direction: it extends outward to open the window and retracts back into the unit when closing. A double-layer chain construction improves durability and makes it difficult to break. Integrated overload protection supports reliable operation for 20000 open/close cycles. Smart, robust design provides powerful performance — locking force reaches 2000N and push/pull force is 450N.
