8kg Payload 820mm Reach IP68 Collaborative Robot Arm for Precision Pick and Place

CS68 Collaborative Robot Arm — 8 kg Payload, 820 mm Reach, IP68 Sealed Body

The CS68 industrial robot arm is a six-axis articulated manipulator engineered for production cells where floor space is tight but process precision cannot be traded away. With an 8 kg rated payload, an 820 mm working radius and ±0.02 mm repeatability, this industrial robot arm slots into screw driving stations, adhesive dispensing benches, small-part assembly nests and end-of-line inspection positions that sit inside narrow machine frames or directly beside a human operator. Each CS68 industrial robot arm leaves the factory with an IP68 sealed body, ISO Class 5 cleanroom compatibility and a base diameter of only 150 mm, so the mounting footprint stays smaller than a standard control cabinet. The joint module integrates harmonic reducer, servo motor and output feedback shaft into a single sealed unit, which removes roughly two thirds of the fasteners and cable joints found on conventional arms of the same class. Operators program the CS68 industrial robot arm either through a task-tree graphical interface or through native Python scripting, and the same program can be validated in the virtual controller before the arm is installed on site.

Technical Parameters of the CS68 Industrial Robot Arm

Advantages Built Into the CS68 Industrial Robot Arm

• Compact cell footprint: the 150 mm base and 22 kg body let the CS68 collaborative robot arm mount on a wall bracket or an inverted frame inside equipment that leaves no room for a pedestal.
• Repeatable to 0.02 mm: redundant encoders and an anti-interference feedback layout hold positioning accuracy through long shifts, which matters when the same industrial robot arm also performs press-fit and gauging moves.
• IP68 sealing as standard: coolant mist, metal dust, flour dust and washdown spray are handled without an add-on protective cover, cutting the owning cost of every deployed industrial robot arm.
• 100,000 hour MTBF design basis: the harmonic drive, motor and feedback shaft are integrated and life-tested as one assembly, with brake durability verified beyond 100,000 category-1 and 10,000 category-0 emergency stops.
• Open control: 24 DI and 24 DO on the controller, Modbus TCP/RTU, PROFINET slave, EtherNet/IP slave, FINS TCP and RS485 allow the CS68 industrial robot arm to talk to a small cell without an extra PLC.
• Fast service: short-lead cable joints and swappable joint modules shorten mean time to repair to minutes rather than a full day.

Typical Applications

• CNC machine tending, material handling, pick&place, controlled fastening in 3C electronics assembly
• Adhesive dispensing, potting and sealant bead tracing on small housings
• Precision pick and place between trays, magazines and indexing conveyors
• Visual inspection, laser marking and functional test loading
• Machine tending for compact CNC lathes, drill-tap centres and stamping dies
• Laboratory sample handling and cleanroom transfer tasks

Frequently Asked Questions

Q: Can the CS68 icollaborative robot arm work as a cobot beside operators without a fence?
A: Yes. The CS68 collaborative robot arm is certified to ISO 10218-1 and ISO 13849-1 PL d Cat.3 with multi-dimensional collision detection, a pinch-free wrist design and a status light band on the tool flange, so a risk assessment usually allows shared workspace operation.

Q: How is a true 8 kg payload confirmed on this industrial robot arm?
A: The 8 kg figure is the rated payload including the end effector and workpiece, measured at the flange with the arm at full extension. For offset grippers we recommend derating to about 6.5 kg and running a cycle test in the virtual controller before release.

Q: Which controller and teach pendant ship with the CS68 collaborative robot arm?
A: The CS68 collaborative robot arm is paired with the ERB1C600ME-Mini MINI control box, a 1.5 kg IP20 unit that accepts any mounting angle, and the ERP500 standard teach pendant with a 10.1 inch 1280 x 800 display. The ERP500S safety pendant with three-position enabling switch is available as an option.

Q: How long does commissioning take?
A: Because the CS68 collaborative robot arm ships with a virtual controller that mirrors the real one, programs written offline can be imported directly. Most single-station cells are productive within one working day of mechanical installation.
