三木プーリのツースクラッチ 546モデル製品画像（かみ合い式電磁クラッチ・高トルク伝達・産業用駆動制御）

This is an electromagnetically operated clutch that activates when an electric current is applied to the coil. Because power is transmitted through tooth engagement, it is compact yet capable of transmitting very high torque. There are two types: "full-position," which engages at any point around the circumference, and "single-position," which engages at only one specific point during a full rotation.

The armature pickup and release times are reference values measured under no-load, stationary conditions. These times generally increase depending on the magnitude of the load and the operating conditions during connection.
The permissible rotational speeds NF and NS represent the full-position and single-position configurations for parallel-toothed gears, respectively.
