Now all new: the garage door operator of the next generation

Faster. More secure. More intelligent. Brighter.

The all new SOMMER base+ is a class of its own. The garage door operator was re-developed from scratch. The intelligent carriage provides plenty of room for installing sophisticated accessories.

Traveling motor

  • gear-spearing technology

    for long-lasting life-time and little wearout
  • galvanized, nickel plated chain

    no friction loss by revolving track, no need for retightening or oiling the track
  • energy saving: < 1 watt in standby mode

    only 0,8W in standby mode, that's round about 1,80€ energy cost per year
  • high self-locking force, active closing function and counter pressure on burglary attempt

  • Flexible installation as requested

    There are three alternatives for installation of the separate control unit housing
  • Existing sockets can be used

    Other sockets and elaborate electrical work is not necessary
  • One operator for all uses

    Can be used for sectional doors, overhead doors, swing doors, canopy doors, side hinged doors, side-sectional doors and sliding doors

All in one.

One box fits all.

With the SOMMER base+ you get a universal, ready-to-use complete package. The pre-assembled operator can easily be mounted on the ceiling or to the wall and is compatible with all sorts of garage doors.

Plug and Play

The modular construction system allows you to upgrade your SOMMER base+ with a versatile collection of accessories. All accessories can be easily installed in the appropriate sockets, which are colored and labled.


Magnetic locking, that locks the engine in every position for attacking forces of up to 300 kg. The lock is blocking mechanically and improves the existing burglary protection.


For measuring temperature and humidity of the garage. The carriage will automatically open the door as much as it is needed and provides perfect air circulation. Once the ideal value is reached, the door will be closed again and the risk of molding decreases.


The Memo provides additional memory extension for up to 450 radio commands. If needed, saved data can be transferred to a new carriage.


Additional LED-lighting for the ceiling control. The additional lighting will be connected in parallel to the lighting of the carriage and can be switched on and off via radio control.

Alarm buzzer / warn buzzer

The buzzer offers two options alternatively in one product: If the sound sensor, which is integrated in the motor carriage, detects a burglary attempt the alarm buzzer plays a loud warning sound. The warn buzzer however makes a sound while closing. 

Park position laser

The park position laser gives you an optical assistance to park your vehicle in the garage perfectly. The laser is active while the door is opening and stays active as long as defined in the duration settings.


Additional relay for additional switching of a garage or courtyard light.


Uses a passive infrared sensor to detect the invisible thermal radiation of moving bodies (humans/animals, etc.) and reacts to them. The operator lighting (additional lighting/relay) switches on automatically for safe movement when the garage is entered.


Assumes the power supply of the operator for > 5 door cycles in the event of a power failure.
