Technical Description: Koganei AFDPG-12-JB
The Koganei AFDPG-12-JB is a premium 12mm flat-type parallel air hand designed for applications requiring high gripping force and delicate part protection. The «-JB» designation identifies the closed-side stroke adjustment mechanism. This feature allows technicians to set a mechanical end-stop for the finger closing movement, which is essential when handling fragile workpieces that could be crushed or damaged if the fingers were allowed to close fully under full pressure.
Advanced Mechanical Rigidity
The AFDPG-12-JB utilizes a high-accuracy linear guide to support its parallel fingers. This guide provides the necessary rigidity to prevent finger deflection under lateral loads, ensuring a consistent grip during high-speed robotic transfers. The 12mm double-piston design ensures a powerful 48 N gripping force at 0.5 MPa, while the thin profile (just 21mm high) makes it perfect for mounting on compact robotic wrists or multi-gripper manifolds.

Operational Efficiency and Reliability
Designed for millions of cycles, the AFDPG-12-JB includes integrated sensor slots on both sides of the body, allowing for the installation of J-series proximity switches. This enables the control system to confirm part acquisition and release cycles accurately. Its lightweight construction (approx. 165g) minimizes the robotic arm’s payload, allowing for faster acceleration and shorter overall cycle times in high-speed manufacturing lines.

Maintenance Insights
To ensure the longevity of the AFDPG-12-JB, always use a 5-micron air filter and properly regulated air. In high-vibration applications, it is advisable to periodically check the stroke adjustment locking nuts. The unit is designed for reliable operation in cleanroom-standard environments with minimal particulate generation.
