International Standards
Selection considerations
 |
(1) The standard specification home position is set on the opposite side to the motor. Check the home position in the dimension drawing. (2) Do not use the product with a thrust from a conveyor or other device that is greater than the allowable load of 200N. (3) A floating mechanism is provided between the rod end bracket and the front bracket to absorb shock. Therefore, the rod end bracket has play in the axial and rotational directions. This product is designed exclusively for stopper use, so if you are using it for positioning purposes, please consider EC-SRG9. |
Dimensions
ST: Stroke
ME: Mechanical end
SE: Stroke end
(Note) When performing a return to origin, the rod moves to the ME, so be careful not to let it interfere with surrounding objects.
(Note) Please note that if you select the brake option with a stroke of 30 mm, the motor unit will protrude beyond the front bracket.
Stroke dimensions
| stroke | 30 | 50 |
|---|---|---|
| L | 135 | 155 |
| B | 110 | 130 |
| C | twenty four | 44 |
| K | 29 | 39 |
Mass by stroke
| stroke | 30 | 50 | |
|---|---|---|---|
| Mass (kg) |
No brakes | 1.8 | 2.0 |
| With brake | 2.1 | 2.3 | |
Correlation diagram between workpiece mass and workpiece collision speed
(※1) Please use within L dimension 50mm.
(※2) The thrust from conveyors, etc. should not exceed the allowable load of 200N.
(*3) The actuator cannot withstand loads from the side.
