Hettich Sensys 8657i Hinge - TH52 for 15-32 mm thick doors; Opening angle 165 Degree (Zero Protrusion Hinge)_Corner Soft Close Hinges

The Hettich Sensys 8657i represents the top tier of wide-angle concealed hinge engineering. Designed specifically for high-end modular kitchens and specialized wardrobe installations, this hinge combines an extraordinary 165^\circ swing range with a crucial Zero Protrusion design.
For modern cabinetry equipped with internal pull-out drawers or wire pantries, standard 105^\circ or 110^\circ hinges pose a common problem: the door overhangs into the carcase opening, blocking internal drawers from sliding outward. The Sensys 8657i eliminates this completely by pushing the shutter entirely outside the cabinet frame as it opens.
Accommodating door thicknesses from 15 mm up to 32 mm, the 8657i handles thick wooden shutters, profiled doors, and heavy corner units effortlessly. Hettich's Silent System hydraulic dampening is built directly into the hinge body, catching the door mid-flight for a smooth, whisper-quiet close. Built with award-winning German precision and finished in corrosion-resistant nickel-plated steel (or Obsidian Black variants), the Sensys 8657i ensures reliable, smooth operation over thousands of cycles.

1. What does "Zero Protrusion" mean, and why is it required?
Zero Protrusion means that when the cabinet door is swung open to 90^\circ or more, no part of the hinge arm or door protrudes into the interior width of the cabinet opening. This feature is essential when installing internal pull-out drawers, wire baskets, or tall pantry pull-out systems, as it prevents the pull-out hardware from colliding with the open door.
2. Can the Sensys 8657i be used for corner cabinet installations?
Yes. Due to its wide 165^\circ opening angle, the 8657i is frequently used as a primary corner hinge for bi-fold doors, corner L-shaped cabinets, and corner base units where maximum access is necessary.
3. Does the 165^\circ opening angle mean the door might hit an adjacent wall?
If the cabinet sits flush against an adjacent wall or nearby furniture, opening the door all the way to 165^\circ could cause contact. If clearance is limited, Hettich offers an optional opening angle limiter clip that restricts the swing angle (e.g., down to 120^\circ or 90^\circ) to prevent collisions while retaining the soft-close feature.
4. What is the difference between Sensys TH52 and TB / TS drilling patterns?
* TH52 (This Hinge): Features standard 35 mm cup cutout with 52 mm screw hole spacing designed for direct screw-on installation.
* TB / TS Patterns: Designed for automated insertion or alternative expansion-socket fixing with different screw-center dimensions (such as 45 mm or 48 mm).
5. What door thicknesses can this hinge accommodate?
The Sensys 8657i accommodates door thicknesses from 15 mm to 32 mm. Standard 110^\circ hinges generally top out at 22–24 mm thickness before edge-rubbing occurs, making the 8657i the ideal choice for extra-thick, lacquered, or profiled cabinet doors.
