Safety first with the emergency solenoid arrestor from Kendrion
In production and intralogistics, intelligent systems that meet the demand for flexibility and automation are becoming increasingly important. In particular, Automated Guided Vehicles (AGVs) that can transport loads from A to B entirely independently are conquering the industry. Besides, collaborative lightweight robots are in demand which automate simple tasks in feeding and assembly.
For such transport handling robots that operate in close contact with humans, reliant arrestor systems are needed that stop the movement immediately in an emergency and guarantee a high degree of fail-safety.
The Kendrion emergency solenoid arrestor is a combination of a specially designed linear solenoid and e.g. a gear wheel or a star wheel, which is mounted by the customer. In the energised state, the pin of the magnetic solenoid arrestor is retracted. In the event of an emergency, the robotic joint locking is switched off and falls into the gear wheel, thus stopping the movement. The solenoid arrestor system guarantees a high level of safety in an emergency and when the system is at a standstill. The travel distance until the application stops is mainly determined by the distance between the points of entry in the rotating counterpart. For low current consumption in the open state, the retracted position is reached once using overexcitation. Afterwards, the position is maintained with a lower holding voltage to save energy.
Frequent areas of application are:
- Robotic joint locking in collaborative robots (cobots)
- Emergency solenoid arrestor in Automated Guided Vehicles (AGVs) such as driverless forklifts
Emergency solenoid arrestor and safety I/O solution from a single source
In addition to the emergency solenoid arrestor, Kendrion offers a CODESYS controller with integrated safety functionalities (FSoE) for use in automated guided vehicles, for example. The safety I/O solution from Kendrion impresses with a compact system that can be used to safely record all digital and analogue signals.

Safe stopping of handling robots and AGVs
The electromagnetic emergency locking system is ideal for stopping the wheels of automated guided vehicles. A reliable linear solenoid acts as a locking bolt, which engages in the gear wheel of the drive shaft in an emergency or when the vehicle is stationary. The robot joint lock - installed in collaborative robots (cobots) - works on the same principle.
The electromagnetic emergency locking system from Kendrion is particularly impressive due to its compact design, low power consumption and high functional reliability.
