User-friendly Design for Faster Deployment

The CR20A adopts an industry-first dual-channel end effector design, which can directly connect to multiple end tools. It also features a visual status indicator at the base for intuitive recognition of operating status.

More Possibilities with High Payload and Wide Radius

The CR20A has a working radius of 1,700 mm and a maximum payload of 20 kg. With advanced motion control algorithm, the CR20A operates more stably, with residual vibrations reduced by 50% during high-speed emergency stops.

24 Interface Ports for Greater Flexibility

The CR20A supports Profinet and Ethernet/IP communication protocols and connects seamlessly with PLC. It has 24 digital IO ports with industry leading support for PNP and NPN switching to expand applications with ease.

High Protection Level for Safer Collaboration

The robot body and control box both achieve a high protection level of IP54. When overloaded, the robot will automatically sound an alarm. The CR20A also features an innovative electromagnetic brake protection, which reduces the end tool drop distance at power failure.
