Safe Machine Door Actuator (SMDA)
Safe, Fast and Efficient Automation for Horizontal Machine Doors
Automating machine door operation is important for the protection of workers and expensive equipment. The SMDA line offers a complete end-to-end solution with a maintenance-free direct drive motor, a compact controller and intelligent operating software. The drive, which is based on proven technology for pedestrian passages, is fitted with a protective function that triggers an immediate change of direction if an obstacle is encountered. SMDA ensures that the force and permissible kinetic energy are compliant with EN 12453, and EN 14120 is safely maintained.

Key Advantages:

  • Immediately changes direction when the door encounters an obstacle
  • Integrated safety: Safe force and speed limits for horizontal doors weighing up to 1,650 lbs (750 kg)
  • TÜV certified (N-13849-1 PLD) iMotion® technology for personnel access
  • Tested Safety: Compliant with EU Machine Directive 2006/42/EC
  • Space-saving design and low voltage operation
  • Easy commissioning with SMDTuner Intelligent Operating Software
  • Maximize tact time with rapid opening and closing
  • Maintenance free

Typical areas of application:

Automating machine door operation can make your machines more efficient and easier to use, but they can also bear some risk. The system helps to minimize risk for operator and machine and prevent irreversible damage.

  • Machine tools (lathing, milling, grinding etc.)
  • Die casting machines
  • General production machines

Why Automate Horizontal Machine Doors?

The use of automatic door drives in modern machines has increased in recent years. The trend towards automating every possible machine function also includes opening and closing the doors of protective machine hoods. Loading and unloading machines represents a particular source of danger for both the operating personnel and expensive loading robots.

These protective machine door actuators include the technology for implementing a safe force and speed limit for horizontal doors with door weights up to 750 kg and more. This enables safe compliance with the approved forces without requiring additional safety elements such as light barriers or two-handed operation. The drive is fitted with a protective function which triggers an immediate change of direction to prevent irreversible damage if an obstacle is encountered.

The intelligent operating software – SMDTuner – assures efficient commissioning of the drive. Thanks to the integrated AutoTuning, there is virtually no need to perform settings during commissioning.  The system is powered by 115/230VAC, features galvanically isolated 24VDC I/O, and has an opto-isolated interface to the machine PLC.  The SMDA drives continue to offer valuable support for implementing safe and reliable automated protective doors.
