Attention:
The actuating range may vary depending on the substrate material and installation situation.
Typical actuating range
(Only in combination with actuator CES-A-BBA, CES-A-BCA)
![<p>Typical actuating range<br>(Only in combination with actuator CES-A-BBA, CES-A-BCA)</p>](https://assets2.euchner.de/files/22/19/ast_632219.png)
For a side approach direction for the actuator and safety switch, a minimum distance of s = 4 mm must be maintained so that the actuating range of the side lobes is not entered.
Typical actuating range
(Only in combination with actuator CES-A-BPA)
![<p>Typical actuating range<br>(Only in combination with actuator CES-A-BPA)</p>](https://assets2.euchner.de/files/23/78/ast_632378.png)
For a side approach direction for the actuator and safety switch, a minimum distance of s = 6 mm must be maintained so that the actuating range of the side lobes is not entered.
