The safety door switch with key SG-B2 series locks and unlocks doors with keys.
When an operator takes a key into a hazardous area, the safety door switch will not lock, and the equipment will stop, ensuring operator safety by preventing personnel from being closed inside the hazardous area and preventing equipment from starting to operate.

Safety worker

Hazards of the system and robot are isolated by the safety guard. The worker uses the key to unlock the door and disables the system from starting unexpectedly, then removes the key and brings it into the hazardous area. The system remains off until the worker walks out the door and locks the door with the key. This enables the worker carrying the key to work safely in the hazardous area.

Energy-saving design, no power supply required

Since doors are locked and unlocked with a key, there is no need to supply power to the safety door switch.

Head removal detection function

Head removal detection function is employed in the SG-B2. With this innovative function, the monitor circuit (41-42) turns off when the head is removed from the switch, such as when removing the head to change the head direction.
With the head installed on the switch, monitor circuits 41-42 and 51-52 operate in synchronization while the key locks / unlocks the actuator.
When the head is removed, 41-42 turns off and 51-52 turns on.
This disagreement is detected by the head removal detection function.
