2 pieces high-quality spring hinge, torque: 12.3 N·m, made of solid stainless steel SUS304 (V2A or 1.4301), surface: natural (untreated), TH-61SUS-3, size: 38 mm (1-1/2″)

Application:

Robust spring hinge for equipment flaps, enclosure doors, covers, and much more.

The TH-61SUS-3 spring hinge supports the automatic opening of flaps and light doors via an integrated spring in the hinge pin.

The spring force acts in the opening direction, thereby assisting the swinging open of movable components.

The hinge's free position is at 90°, making it particularly suitable for equipment flaps, covers, and enclosure doors.

Constructed entirely from SUS304, it offers high corrosion resistance and is also suitable for more demanding operating conditions and long-lasting technical applications.

Four mounting holes allow for simple and secure screw-in installation.

With compact dimensions of 38 mm (1-1/2″) x 51 mm (2-1/64″), the spring hinge can be integrated into equipment, enclosure, and machine designs to save space.

The high-quality TH-61SUS-3 spring hinges are ideal for, among other things:

• Maintenance flaps, machine panels, office equipment, communication devices, measuring instruments
• Equipment flaps
• Enclosure doors
• Covers

Material:

• The TH-61SUS-3 spring hinges are made of solid stainless steel SUS304 (V2A or 1.4301)
• Stainless steel SUS304 is characterized by its high corrosion resistance and durability, making it ideal for use in demanding environments
• In addition, it offers an attractive surface that is both modern and easy to maintain

Surface:

• Natural (untreated)
• The material surface remains visible and is not covered by an additional coating

Installation:

• Fastening is performed using 4 x M3 pan-head or round-head screws, preferably made of stainless steel (not included in the scope of delivery)
• The TH-61SUS-3 spring hinge has 4 mounting holes
• First, the mounting points must be marked according to the hole pattern of 25 mm (63/64″) x 32 mm (1-17/64″) and the necessary mounting holes must be prepared
• The spring hinge is then attached with one hinge leaf to the fixed surface and the other hinge leaf to the movable flap or door
• The installation direction must be chosen so that the spring force acts in the desired opening direction
• Four M3 pan-head screws, or for wooden surfaces, screws with ⌀3 mm, are suitable for fastening
• The screws must be tightened evenly without deforming the hinge leaves
• Finally, the flap should be moved several times to check the desired opening effect of the spring hinge (for further details, see installation drawing)
