| Part number | Breaking torque adjustment range (N⋅m) | L (mm) | X (mm) | Ymax (mm) | (Z) (mm) |
|---|---|---|---|---|---|
| 4TF-007C | 0.3 to 0.7 | 21.2 | 1.1 | 2.2 | 0.7 |
| 4TF-010C | 0.4 to 1.0 | 21.4 | 1.3 | 2.4 | 0.5 |
| 4TF-030C | 1.0 to 3.0 | 21.2 | 1.1 | 2.5 | 0.7 |
| 4TF-045C | 1.5 to 4.5 | 21.4 | 1.3 | 3.3 | 0.5 |
- X: When an overload is applied, the overload detection panel moves X mm. Using this movement, use the detection switch to control the operation.
- (Z): This dimension is a reference value for the amount of projection of the torque adjustment nut when the spring is at its free height, so be careful not to interfere, etc., with peripheral equipment at the mounting area. The (Z) dimension may vary due to variations in spring free height.
* If the dimension is negative, the boss side will protrude. - Y: This dimension is the amount of spring deflection from the free height of the spring, so read the amount of spring deflection Y from the cutoff torque in the torque characteristics chart, and set the cutoff torque by tightening the torque adjustment nut by the Y amount read.
* Do not tighten beyond the Ymax value shown in the specifications table, as operation will be disabled.

Cautions and Prohibitions
1. If the selection and handling of fastening elements are not appropriate, the desired performance may not be obtained.
2. Determine the length of the mounting bolt after checking the depth of the mounting tap. If the bolt is too long, the flange and boss will be locked and unable to rotate.
* It is recommended to use a hook wrench when turning the torque adjustment nut.
