- Large 70 mm total stroke The combined 70 mm stroke accommodates a wider range of object sizes than many comparably compact grippers, so one tool can handle both small parts and larger fixtures without tooling changes.
- Integrated controller, all-in-one design The controller is built into the gripper assembly, reducing external drive requirements and simplifying wiring in small robotic wrists and cobot toolheads for quick deployment.
- Closed-loop force and position control Gripping force is tunable across 0–20 N in ±1 N steps with ±0.50 mm repeat positioning accuracy, letting you adapt grasp behavior for rigid parts or more delicate surfaces.
- Built-in pressure sensing An integrated pressure sensor supports threshold-based control — set different pressure thresholds to grip objects of different hardness, reducing crushing risk and improving consistency.
- Power-off self-locking The gripper is designed to maintain its grasp during a power interruption (subject to load, friction, and application conditions), helping prevent accidental drops.
- RS485 with MODBUS RTU The RS485 interface supports MODBUS RTU for straightforward PLC and robot-controller integration, with MODBUS and CAN protocol supplements, software utilities, and 3D models available from the manufacturer.
Description
The Inspire EG2-4C is a two-jaw electric gripper from Inspire Robots — often referenced as the EG2-4C2 within the series — that combines a large stroke, integrated control electronics, and closed-loop force and position control in a self-contained 231 g package. Its total stroke of 70 mm (both sides combined) is a standout for the size class, allowing a single tool to grasp both small parts and larger fixtures without changing tooling. Gripping force is adjustable across 0–20 N in ±1 N steps with ±0.50 mm repeat positioning accuracy, and a built-in pressure sensor enables threshold-based gripping, letting users set different pressure thresholds for objects of different hardness to reduce crushing risk and improve handling consistency. Power-off self-locking helps the gripper maintain its grasp during a loss of power (subject to load, friction, and application conditions).
Because the controller is integrated into the gripper assembly, external drive hardware is minimized and wiring into small robotic wrists and cobot toolheads stays simple — the unit runs from DC 24 V and communicates over RS485 with MODBUS RTU support, with supplementary MODBUS and CAN protocol documentation, software utilities, and 3D models available through the manufacturer's support resources. Typical applications include pick-and-place of components and subassemblies, machine tending for small parts, packaging and kitting, and fixture loading in bench-scale automation, as well as university and lab projects such as mobile manipulators and grasping research where repeatable force and position control is useful. As an electric gripper it also suits service robots and field prototypes, since it needs no compressors, valves, or air lines.

Frequently Asked Questions
Some storefronts describe it that way, but the EG2-4C is most accurately characterized as a two-jaw electric gripper. It emphasizes a large 70 mm stroke, integrated control electronics, closed-loop force and position control, and power-off self-locking rather than multi-finger dexterity.
It is commonly deployed for pick-and-place of components and subassemblies, machine tending for small parts, packaging and kitting workflows, and fixture loading in bench-scale automation. It is also popular in university and research settings for mobile manipulators and grasping experiments, and in service robots and field prototypes where pneumatic infrastructure is unavailable.
The gripper communicates over RS485 with MODBUS RTU support and runs from DC 24 V, with the drive controller integrated into the body. Force thresholds can be set via its built-in pressure sensor for contact-aware gripping, and the manufacturer provides MODBUS and CAN protocol supplements, software utilities, and 3D model resources.
The Inspire Robots RH56F1 is a multi-fingered dexterous hand designed for humanoid-style manipulation, while the EG2-4C is a two-jaw parallel gripper optimized for repeatable pinch grips across its 70 mm stroke with tunable 0–20 N force. For standard part handling, tending, and kitting tasks, the EG2-4C is the simpler, purpose-built choice.
The EG2-4C is covered by the manufacturer's warranty as provided by Inspire Robots. To order or request pricing, contact the Robotix Market team through the website's quote or inquiry form and we will confirm pricing, availability, and worldwide shipping.
