12kg Payload 1304mm Reach IP68 Collaborative Robot Arm for Flexible Welding

CS612 Collaborative Robot Arm — 12 kg Payload, 1304 mm Reach, IP68 Sealed BodyIndustrial

The CS612 collaborative robot arm extends the CS platform to a 12 kg rated payload and a 1304 mm working radius, which is the size class where machine tending, pallet pattern building and long-reach inspection become practical without moving to a caged industrial cell. Repeat positioning accuracy is held at ±0.03 mm and maximum tool speed rises to 3.4 m/s, so the CS612 industrial robot arm keeps cycle time short even when the tool travels the full 1304 mm envelope. The body is sealed to IP68 across the whole series and rated for ISO Class 5 cleanroom work, and the 190 mm base still fits on a machine frame or a wall bracket because the arm can be mounted at any angle. A 34 kg body mass and a 435 W typical power draw mean the CS612 industrial robot arm can be redeployed between two machines on the same skid without a new electrical design. Programming follows the same task-tree graphical environment or native Python scripting, and every industrial robot arm in the CS series shares the ERB3C controller family, which simplifies spares strategy across a mixed fleet.

Technical Parameters of the CS612 Industrial Robot Arm

Advantages Built Into the CS612 Collaborative Robot Arm

• Long reach in a light body: 1304 mm of working radius from a 34 kg collaborative robot arm lets one unit serve two machine doors or a full pallet pattern without a linear track.
• High throughput: 3.4 m/s tool speed and 180 °/s wrist joints shorten handling cycles, which is the decisive figure when the CS612 industrial robot arm feeds a machine whose cutting time is under two minutes.
• IP68 from the factory: graphite dust, coolant, high humidity and washdown are tolerated, so the industrial robot arm can sit inside grinding or deburring enclosures.
• Single-family controller: the ERB3C1K0 AC controller shares I/O layout, bus options and spare parts with the rest of the CS series, so a plant running several industrial robot arms stocks one controller type.
• Safety engineering: Cat.3 PL d architecture, collision detection, a wrist without pinch points and an independent safety controller make fence-free operation realistic after a documented risk assessment.
• Digital twin workflow: the virtual controller reproduces the real controller one to one, so reach studies, cycle estimates and PLC handshakes for the CS612 industrial robot arm are finished before the crate is opened.

Typical Applications

• CNC lathe and machining centre tending with double gripper exchange
• Case packing, carton palletizing and depalletizing at end of line
• Arc welding, laser welding and press brake tending
• Grinding, deburring and polishing with force control
• Battery module handling and photovoltaic component transfer
• Long-reach inspection, metrology loading and warehouse picking

Frequently Asked Questions

Q: What separates the CS612 collaborative robot arm from a 12 kg caged robot?
A: The CS612 collaborative robot arm is built to ISO 13849-1 PL d Cat.3 with force-limited collision detection, so it can share space with people when the risk assessment supports it. It also runs on 435 W typical power and weighs 34 kg, which keeps installation and power infrastructure simple.

Q: How much payload remains after fitting a double gripper?
A: The 12 kg rating includes the tool. A typical double gripper weighs 3 to 4 kg, leaving about 8 kg for the part, so two 4 kg blanks can be exchanged in one move. For heavy tools we recommend the CS616 or CS620 industrial robot arm from the same family.

Q: Can the CS612 industrial robot arm be integrated with an existing PLC and MES?
A: Yes. The ERB3C1K0 controller offers 16 DI, 16 DO, configurable IO, 2 AI and 2 AO plus EtherNet/IP slave, PROFINET slave, Modbus TCP/RTU, FINS TCP and RS485, and real-time status data can be pushed to MES or SCADA over the same network.

Q: What is included in a standard delivery?
A: Each CS612 collaborative robot arm ships with the arm, the ERB3C1K0 control box, a 5.5 m standard cable set and the ERP500 teach pendant. The ERP500S safety pendant, the MINI control box and application grippers are quoted separately.
