DOM ix Teco® (7TE) double cylinder

System ix Teco® (7TE) "Easy access to superior security"

The new ix Teco® reversible key (commercial profile ix 7TE) is particularly well protected against unauthorized copying by an innovative additional stamped recess in the key, based on a patented technology. A special high-low (HT) milling technology in the horizontal base profile increases security during profile control and is difficult to copy. With the innovative and sophisticated design, you acquire a locking system with efficient key copy protection, which is predestined for use in the locking system, but also for individual locks.

Patent protection until 2038

Reversible keys with special high-low milling (HT)

The DOM System ix Teco® (7TE) has a patented high-low milling in the key and thus offers a high technical key copy protection and high manipulation protection against opening techniques.

Impact protection

The cylinder contains impact protection pins and other safety elements that prevent access by impact keys to turn the inner pins.

Unlocking protection

The cylinder contains specially shaped unlocking security pins that prevent opening with the help of a lock pick.

Pulling protection

The cylinder contains a special cylinder core which prevents the cylinder from being pulled out by drilling into the core.

How to measure the cylinder length correctly?

You can also find help in determining the correct length in our Help Center for "Cylinder Gauge.

Increased drilling and core pulling protection (on request)

The cylinder is provided with increased drilling and core pulling protection by means of carbide pins arranged in several planes in the cylinder body and cylinder core.

Cylinder finishes (on request):

  • finishes (polished brass, oxidized bronze, matt black chrome)
  • standard finish: dull nickel
  • for individual design requirements
  • if desired, homogeneous appearance of door cylinder and fitting
Please note:
If a different cylinder colouring, different from the standard colouring, is ordered, extended production times may occur.

Modular design

The modular cylinder is a profile cylinder in which the different cylinder lengths can be adjusted without great time expenditure using suitable intermediate parts of the respective locking system. This also protects against violent "tearing" and "pulling" on the cylinder (modular technology with increased tear-off protection).

Emergency and danger function

This function enables the locking cylinder to be blocked even if a key with blocking authorisation is inserted on the opposite side.

emergency and danger function

Seawater resistance (on request):

  • for use in marine climate or salty atmosphere
  • fixing screw pure brass, cam sintered steel (chemically nickel plated)
  • cylinder finish: matt chrome
  • restrictions possible in combination with other optional equipment
  • possible from cylinder length 30,5 / 30,5 mm
  • in combination with freewheel: clutch not protected against seawater

Freewheel (on request)

The profile cylinders which have a freely rotating cam are designated as freewheel cylinders.
The cam can be moved freely through 360° when no key is inserted. DOM freewheel cylinders comply with DIN EN 18252:2006-12.
When the key is inserted, the spring-loaded clutch engages in the cam. This then allows the cylinder to be closed in the conventional way with the key.

  • from cylinder length: 35,5/35,5 mm
  • Usually only necessary for special panic or automatic locks. If in doubt, please check with the door manufacturer.
  • for multi-point locks with panic function: latch and bolt must be moved into the lock body when the door is closed with the handle. To ensure this, the cam must be able to turn freely.
  • in motor-driven locks and special escape door locks
  • restrictions possible in combination with other optional equipment
  • this option cannot be combined with the emergency and danger function
  • freewheel function is tested according to FZG (test guideline for profile cylinders with freewheel function for gear locks in escape door locks)
