Denso HS-035A1 vs Epson G10-651

Two scara arms a buyer shopping for pick and place would honestly weigh against each other, with the manufacturer-published figures in one table and a plain reading of what the differences mean on a floor. We sell across brands, so we have no reason to tilt it.

Every figure is a manufacturer-published claim, checked on the date shown against the maker's own material, and not one of them survives contact with your part, your rate and your floor without an applications review. Prices are deliberately absent: quotes are prepared by our team and confirmed with the manufacturer.

What the numbers mean on the floor

Payload is effectively a tie at 5 kg and 5 kg. The gripper and the part decide it, not the arm: rated payload is measured at the wrist with no tool on it.
The Epson G10-651 reaches 300 mm farther than the Denso HS-035A1. That matters for pallet height, bin depth and machine door clearance more than it matters at a bench.
Neither is sold as collaborative. Both need guarding and an integrator's risk assessment before a person shares the floor with them.
Both are listed for pick and place. The Denso HS-035A1 is also listed for assembly and screwdriving, inspection. The Epson G10-651 is also listed for machine tending, material movement.

What a spec sheet cannot tell you

The gripper, the fixture and the integrator decide more of the outcome than the arm. Cycle time on your part is a test, not a datasheet figure. Service footprint, spare parts and who answers the phone at 2 AM differ by brand and by state. And the price difference between two arms in the same class is usually smaller than the difference between two integrators' quotes for the same cell. A model number is not a specification, and the gripper is the project.
