KVG-20S Ultra-Compact Parallel Electric Gripper-20 mm Stroke, 8–20 N

The KVG-20S Ultra is an ultra-compact two-finger parallel electric gripper for automation tasks where space is limited and cycle time matters. Measuring just 43 × 24 × 93.9 mm and weighing 350 g, it delivers 20 mm total stroke, 8–20 N adjustable gripping force and ±0.02 mm repeatability. The drive controller is built into the gripper body — no external cabinet, no compressed air supply required.

Key Features of the KVG-20S Ultra Electric Gripper

Ultra-Compact Footprint

Only 43 × 24 × 93.9 mm and 350 g — fits where standard grippers cannot. Ideal for dense workcells and small collaborative robots.

Fastest Closing in Class

0.15 s for a full one-way stroke (0.3 s round trip) — shortens cycle time on high-speed pick-and-place lines.

4-Level Adjustable Gripping Force

Gripping force adjustable across 4 levels from 8 to 20 N — switch between delicate and firm parts without changing hardware.

Built-In Controller

Drive and controller integrated in the gripper body. No external cabinet, no extra cost, minimal wiring.

Replaceable Fingertips

The fingertip section is interchangeable — machine your own to match specific workpiece geometry.

No Compressed Air Required

Fully electric — replaces air compressor, filter, solenoid valve and pneumatic gripper. Ideal for labs, hospitals and clean environments.

Frequently Asked Questions

Is the stroke adjustable?

No. The KVG-20S Ultra has a fixed 20 mm total stroke (10 mm per jaw). If you need adjustable stroke, see our KVG-20S Pro series.

How is the gripping force adjusted?

Force is set across 4 discrete levels from 8 to 20 N.

Does it support Modbus communication?

The KVG-20S Ultra uses digital I/O control. For Modbus RTU (RS-485), see our KVG-20S Pro model.

Is the controller included?

Yes, the drive controller is built into the gripper. No extra charge.

Can I use custom fingertips?

Yes. The fingertip section is replaceable and can be machined to your workpiece.

What maintenance is required?

Replenish grease on moving components every 6 months or 1 million cycles.
