Overview

The EG2-4B2 is a compact electric gripper built on an innovative linear mechanical linkage design — delivering precise force and position control, a large 70mm full stroke, and power-off self-locking in a 223g package. Unlike pneumatic grippers, the EG2-4B2 requires no compressor or air supply: a single RS485 connection handles all motion and feedback.

Grip force is continuously controllable from 0 to 15N with ±1N repeatability, allowing the same gripper to handle fragile items at low force and firm parts at full force without hardware changes. Power-off self-locking holds the grip position when power is cut — no energy draw, no part drop. IP40 rated for standard industrial and laboratory environments.

Key Features

• 0–15N grip force — continuously controllable across the full range with ±1N force repeatability
• 70mm full stroke (both sides) — large opening range accommodates varied part sizes
• Power-off self-locking — holds grip position without power; no energy draw, no part drop on power loss
• Linear mechanical linkage design — integrated controller, force and position control in a single compact unit
• ±0.5mm positioning repeatability — consistent, reliable part placement across cycles
• 0.85s full stroke closing time — fast enough for high-throughput pick-and-place cycles
• Maximum speed 97mm/s — fastest in the EG2 lineup
• 223g — lightweight for minimal impact on robot arm payload budget
• RS485 control — simple single-cable integration with any RS485-compatible robot arm or controller
• IP40 protection — rated for standard industrial and laboratory environments

Specifications
