Stopper Bolt Switch

Stopper Bolt Switch

Dual functions in one: Stopper bolt with a built-in touch switch sensor.

Stopper bolt simultaneously stops the workpiece and outputs confirmation signal from the touch switch sensor.
The conventional dogging and intermediary mechanism for activating the sensor is unnecessary, resulting in downsizing of the machine.
