DOM ix 6HT


"simple to use - difficult to outsmart"

The DOM ix 6HT system is the entry into the world of reversible keys. It is a system with a multi-stage security concept that offers a high level of protection through the interaction of many technical details. A special high-low milling (HT) in the horizontal basic profile provides additional security during profile control and is extremely difficult to copy. This quality product from DOM achieves protection against mechanical manipulation by using high-strength materials.

This system is available for reorders only.

For new systems we recommend the series DOM ix Teco® (7TE).

DOM ix 6HT

Technical characteristics:

  • high protection against manipulation by 19-fold locking authorisation query
  • anti bumping (impact key protection) & anti picking pins (picking protection)
  • up to 12 horizontal and vertical profile control pins: control points for the authorization query of a key
  • 6 spring-loaded pin locking elements on each locking side, axially arranged, made of special brass/hardened steel offer protection against manipulation
  • 12 core and body pins
  • narrowed core and body pins for safety during scanning and unlocking
  • drilling protection (standard): 2 hardened steel pins in the body, 1 hardened steel pin in the cylinder core
  • 13 mm core diameter
  • one-piece cam made of sintered steel
  • concave core head as key insertion aid
  • according to DIN EN 1303:2015-08, certified according to ISO 9001:2015
  • locking security class 6, attack resistance class B (locking system class C) according to DIN EN 1303
  • patent protection until 2026

DOM ix 6HT key

Operational area:

  • larger residential areas
  • apartment buildings
  • small and medium-sized commercial properties

Options / Special equipment:

  • different cylinder finishes (polished brass, oxidized bronze, matt black chrome)
  • increased drilling protection
  • emergency and danger function
  • weather protection
  • modular design
  • freewheel (on request)

Explanations on the optional extras:

Increased drilling and core pulling protection:

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:

  • 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.

Seawater resistance:

  • 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


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)

Modular design:

The modular cylinder is a profile cylinder in which the different cylinder lengths can be adjusted without great time expenditure by means of 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).
