Time, space and a high safety category are essential factors for many machines today. This is why Jokab Safety has developed a new small and robust E-stop. The size and the centered mounting holes make it easy to install, especially on aluminium extrusions which are today frequently used for machine building and safe guarding. The 'Smile' E-stop unit has one or two M12 connectors enabling quick installation and easy replacement. The outputs provided are either two dual ' braking' contacts or a Tina interface which makes it possible to connect several E-stop devices in a dynamic safety circuit according to category 4. LED indication of E-stop status is also provided.
