Rotary latch
The Rotary Latch is an industrial-grade door locking component that achieves automatic latching through the positive engagement of a rotating jaw with a striker. It is characterised by smooth, controlled closure, reliable locking retention, and outstanding resistance to vibration and loosening, and is equally suited to mobile and stationary applications.
The product is widely used in vehicle access hatches, construction machinery, battery cabinets, energy storage systems, industrial equipment enclosures, rail transit vehicles, and heavy-duty access doors.
This series supports both single-stage and dual-stage locking, and is fully compatible with mechanical cable actuation, electric actuators, external handles, and remote control systems, allowing flexible integration into manual, semi-automatic, and fully automated door systems.
Built for high-cycle operation in demanding and vibration-intensive environments, the Rotary Latch incorporates concealed panel mounting, waterproof and dustproof sealing, anti-misoperation protection, and multi-point interlocking capability, meeting the safety, sealing, and operational requirements of a wide range of industrial equipment.
