Sliding Gates

Sommer SP 900

A beautifully aesthetic, post integrated sliding gate motor


The complete operator of the SP 900 is integrated into the post of the sliding gate. This makes the operator invisible and provides for an uncluttered appearance. The SP900 is flexible, rugged and suitable for industrial door systems.

For sliding gates with a travel length of up to 8 m and a gate weight of 400 kg.


Protection for you and your loved ones
The operator learns on its own and runs in the currently optimal way thanks to the DPS (Dynamic Power System). It adapts to the environment and always moves at the same speed. For the operator, obstacles mean that it suddenly needs more force. In this case, it stops or reverses. This prevents injury and damage to property. SOMMER also offers additional safety accessories. (Photo eyes, safety contact strips, etc.)

Safety due to automatic locking
The integrated electric lock ensures effective self-locking and break-in protection. If there is an attempt to slide the operator, it counteracts the force with automatic locking.

Safety due to dead-man function
A pre-warning system and an adjustable dead-man function are integrated for higher safety.

Long lifetime thanks to gentle soft running
The gate and the operator are preserved thanks to the “Open” and “Close” soft running. Shortly before the gate end positions, the speed decreases, which preserves the mechanics and increases the lifetime. No annoying closing noises.

Adjustable door opening direction
The door opening direction can be set to the left or the right using selection switches. That means that no rewiring of motor and end switch is necessary. The carriage can be flexibly adjusted by simply setting a DIP switch.

Battery pack for power failures
During a power failure, the operator can be run in emergency mode with our battery pack.

Environmental and cost efficiency
Consumption of electricity and environmental impact are low thanks to the efficient ring core transformer.

Functions which make daily life easier
The partial opening function can be used to open a part of a gate and reach the property by bike, for example.
With the automatic closing function, you can be sure that the gate is always locked behind you. After the photo eye is passed, the gate automatically closes after a set time.
