Reliably gripping and turning small parts

Compact rotary gripper module EHMD from Festo

The extremely compact rotary gripper module EHMD is the ideal choice in many applications where small objects need to be gripped and turned in confined spaces. For example, it can be used in laboratory automation to open small sample vials with ease. The Z module automatically adjusts to the thread pitches of the caps, eliminating the need for head/adapter changeover times.

Whether for in-vitro diagnostics, cell or genome research or quality inspections in the biotech and pharmaceutical industries, the rotary gripper module EHMD is completely reliable. This holds true for preparing and analysing samples, loading centrifuges, gripping, rotating and placing microwell plates or even opening and closing sample vials of different sizes.

Combined with a 3D gantry and a camera, it can support quality inspections with cameras, recognise bar codes, or print labels with a label printer. It is also perfect for use in light assembly or in the electronics industry.

Pneumatic or electric
The EHMD comes in two versions: fully electric or with a pneumatic gripper. Both permit infinite rotation. The optional assembly module with Z compensation automatically adjusts to the thread pitch of the caps without moving the Z-axis. When powered by the motor controller CMMO-ST from Festo, it allows sample containers of unknown size to be gripped with varying levels of force.
