To order a replacement Hettich concealed hinge, note which hinge it is, how the door sits on the cabinet and which mounting plate holds it. This guide shows where Hettich prints them for Sensys and Intermat 9930 hinges, and what Hettich lists for its Optimat face frame hinges.
Sources: Hettich's US brochures The design hinge with integrated Silent System: Sensys and Hinge technology for face frame cabinetry: Optimat (page numbers are PDF pages, not printed page numbers, of the Sensys brochure unless Optimat is named). Overlay, inset and plate terms are explained in our concealed cabinet hinges guide and our Richelieu replacement hinge guide. Hettich prints order numbers with spaces: 9 071 223 is our 9071223.
Which Hettich Sensys or Intermat hinge do you have
A selection from the Sensys brochure hinge pages (8-11 and 15):

Hettich mounting plates: what to read on the old plate
Hinge and plate are separate articles; our 9071223 page (Sensys 8645i, full overlay, for screwing on) says "Plates sold separately". Pages 28-30 and 32-35 are headed "For Sensys and Intermat", page 31 "For Sensys".
- Distance D. "Distance D is embossed on the top of each mounting plate" (page 67). Cross mounting plates are listed in 0, 1.5, 3, 5 and 8 mm (not every plate in every distance), face frame mounting plates in 0 and 4.5 mm, the System 8099 plates in 3 mm.
- Plate type. Among them: cross mounting plate (hole line distance LR 37 mm), face frame mounting plate (LR 9.5 mm) and Inset Face Frame mounting plate System 8099 "For inset doors on Face Frame cabinets".
- Fixing. Options include: for screwing on, for pressing in, with expanding sockets, with premounted Euro or chipboard screws, and the "Hettich Direkt" plate.

Examples on our site: 9071577 (3 mm, for screwing on) and 9084930, which page 31 marks "Can only be used with Sensys hinges".
Plate distance, overlay and cup distance
Page 67: "A larger distance D reduces overlay for full and half overlay applications. On inset doors, a larger distance D increases the door reveal." Its worked example for a full overlay hinge: an overlay of 14 mm and a cup distance C of 4.5 mm give a distance D of 3.0 mm. Minimum reveal and distance tables for the four Sensys hinges above are on pages 16-20; for the Intermat 9930, page 26 gives distance D 0 mm at cup distance 4.5 mm and 1.5 mm at 3.0 mm.
Opening angle limiters, soft opening and cover caps
- Opening angle limiters (pages 39-40): 9072540 limits the Sensys 110 degree hinge from 110 to 85 degrees, 9 090 756 the wide angle hinges from 165 to 105 or 120 degrees. Other limiters are listed, including for the thick door and thin door hinges.
- Soft opening for Sensys wide angle hinge (page 38): for wide angle hinges with integrated Silent System, and it "Cannot be combined with opening angle limiter". 9 100 116 is the half overlay version.
- Cover caps (pages 37-38): the hinge arm cap "Can be used with all Sensys hinges apart from Sensys wide angle hinge", which has its own cap.
Hettich face frame hinges: Optimat
The Optimat pages (4-7) list door thickness up to 3/4" (19 mm), cup diameter 1-3/8" (35 mm), cup depth (minimum drilling depth) 7/16" (11 mm), cup distance 1/8" (3 mm) and a 105 degree opening angle. The angle reduction clip 9 299 081 "Reduces opening angle to 85 degrees".
Optimat clip on with integrated Silent System (page 4):
| Overlay | Screw-on TB 42 | Press-in TB 43 |

Optimat 3D (pages 6-7) adds 1" and 1-1/2" overlays. Our 929476400 and 929476500 pages (3/4" and 1/2" overlay, screw-on) match 9 294 764 and 9 294 765, and 9285006 is the 3/4" press-in hinge above.
For the number of hinges per door, both brochures give a diagram that "must be understood as a guide only" (Sensys page 66, Optimat page 9).
