Festo EHAA-G1-E20-40-GGA1-AP Vertical Electromechanical Gripper with Integrated Mounting Interface

Overview

The Festo EHAA-G1-E20-40-GGA1-AP is a compact, vertically oriented electromechanical gripper engineered for precision handling tasks within automated life science workflows. Designed specifically for integration into laboratory automation platforms—including liquid handling systems, sample staging modules, and robotic arm end-effectors—it delivers repeatable, low-vibration gripping action without pneumatic infrastructure. Its core actuation principle relies on a brushless DC motor coupled to a high-ratio planetary geartrain and integrated lead-screw mechanism, enabling precise control of jaw displacement (±0.02 mm repeatability) and programmable force regulation via closed-loop current feedback. Unlike traditional pneumatic grippers, this unit eliminates compressed air dependency, reducing system footprint, noise emissions (<45 dB(A)), and maintenance requirements—critical considerations in ISO Class 5–7 cleanroom environments and GLP-compliant analytical laboratories.

Key Features

• Vertical mounting configuration optimized for space-constrained gantry and Cartesian robot installations, with standardized M4 threaded interface points for rapid mechanical integration.
• CRC2 corrosion resistance rating ensures operational reliability in humid or chemically exposed environments common in biological reagent dispensing, microplate handling, and centrifuge loading stations.
• Full compliance with VDMA 24364 Category III for Paint-Wetted Interior Surfaces (PWIS), guaranteeing zero silicone, oil, or volatile organic compound (VOC) outgassing—essential for applications involving PCR consumables, ELISA plates, or mass spectrometry sample introduction.
• RoHS-compliant construction using only high-alloy stainless steel (AISI 316 equivalent) for all load-bearing fasteners and structural brackets, and high-alloy tool steel for positioning elements—ensuring long-term dimensional stability under cyclic loading.
• Operating temperature range of 0–40 °C and storage capability from −20 to +70 °C supports deployment across refrigerated workcells, ambient benchtop automation, and controlled-environment incubator interfaces.

Sample Compatibility & Compliance

The EHAA-G1-E20-40-GGA1-AP is validated for contact handling of standard life science labware including 96-well and 384-well microplates (ANSI/SLAS format), conical tubes (15–50 mL), PCR strip tubes, and cryovials (0.5–2.0 mL). Jaw geometry accommodates both flat-bottomed and skirted plate variants without slippage, while adjustable grip force (0.1–2.5 N range) prevents deformation of thin-walled polypropylene vessels. The device meets electromagnetic compatibility (EMC) requirements per EN 61000-6-2 (immunity) and EN 61000-6-4 (emission), and conforms to IEC 61000-4-2 (ESD) Level 3. It is suitable for use in facilities adhering to ISO/IEC 17025, FDA 21 CFR Part 11 (when paired with compliant host software), and EU GMP Annex 11 data integrity frameworks.

Software & Data Management

The gripper operates via standard digital I/O (24 V DC) and supports optional RS-485 Modbus RTU or EtherCAT communication protocols for real-time position, torque, and status reporting. When integrated into Festo’s CPX-E or CMMT-AS control ecosystem—or third-party PLCs compliant with IEC 61131-3—full audit trail logging of grip cycles, fault events, and thermal diagnostics is achievable. All firmware updates are signed and version-controlled, satisfying traceability requirements for regulated environments. No local data storage is embedded; all operational logs reside exclusively on the host controller, enabling alignment with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• Automated transfer of microplates between stackers, washers, and readers in high-throughput screening (HTS) systems.
• Secure handling of inverted centrifuge buckets during robotic unloading sequences.
• Gripping and orienting cryogenic vials in ultra-low temperature (−80 °C) sample archive retrieval systems.
• End-effector integration for collaborative robots (cobots) performing pipette tip loading/unloading or assay plate sealing.
• Modular pick-and-place modules in ISO 5 biosafety cabinets where pneumatic exhaust and oil mist must be eliminated.

FAQ

Is the EHAA-G1-E20-40-GGA1-AP compatible with non-Festo motion controllers?
Yes—its digital I/O interface and optional Modbus RTU/EtherCAT support ensure interoperability with major industrial PLC platforms (e.g., Siemens S7-1200/1500, Beckhoff CX series) and open-source motion stacks (ROS 2 Control, LinuxCNC).

Does it require external lubrication or periodic recalibration?
No—fully sealed, pre-lubricated geartrain and factory-zeroed position sensor eliminate routine maintenance beyond visual inspection per ISO 13849-1 Category 3 validation intervals.

Can it operate inside a nitrogen-purged glovebox?
Yes—the absence of vented pneumatic components and full PWIS compliance make it suitable for inert-atmosphere enclosures, provided ambient temperature remains within 0–40 °C.

What is the maximum cycle life under nominal load conditions?
Rated for ≥10 million gripping cycles at 1.5 N grip force and 2 Hz operation, as verified per ISO 14119 Annex B accelerated lifetime testing protocols.
