It is impossible now to imagine factory and process automation without electric drives. The benefits are clear: they are not only extremely cost-effective to operate, but also very easy to control and configure. Of course, this also applies to electric stoppers from Festo, which are used to stop conveyed goods and thus automate the flow of materials.
The electric stopper EFSD has an integrated motor controller and a combined interface to the power supply. This allows it to be connected directly to the digital I/O of a PLC, and it only has a single energy source, so it does not require compressed air. The power supply, communication and logic processing functions are all integrated in the device itself. The EFSD uses LEDs for status indication and for status and error messages, while the sensor and actuator signals are transmitted via M12 plugs.
The EFSD enables conveyed goods from 0.25 to 100 kg to be gently stopped. It is our attractive solution for quickly and easily equipping transfer systems, completely without compressed air, and is available in three different sizes.
The electric stopper EFSD has three positions. In position 1, the initial position, the stop of the stopper cylinder is extended and ready to stop the conveyed goods. In this position, the LED status message is "Closed" and the input signal is 0.
In position 2, the holding position, the conveyed goods have been cushioned and slowed down by the cushioning built into the electric stopper and are then held in position for a certain period of time. In this position, the LED status message is also "Closed" and the input signal is 0.
Only in position 3, the release position, does the LED status message change to "Open" and the input signal to 1. In this position, the stop of the electric stopper is retracted and the conveyed goods are released.
