• Slim 7 mm profile with a large 50 mm touch surface

• Dual M12 connectors (5-pin and 8-pin, 6 poles used)
• Easy V-mount installation (Ø50–58 mm, 3 screws)

The SC31 is ideal for manufacturers and system integrators seeking a certified, intuitive, and maintenance-free two-hand control solution for safety-critical environments.
