Sugatsune America's stainless steel torque hinge SFTH-02-5 provides controlled movement and position holding for lightweight equipment covers, inspection flaps, and access panels. The friction-generating mechanism resists rotation in both directions. This ensures an appropriately sized panel holds in place at any desired angle.
Its compact, polished stainless steel construction supports integration into sheet-metal assemblies, and with a torque of 5 kgf·cm (4.3 lb·in) per hinge, the SFTH-02-5 is intended for smaller-sized lids.

- Compliance: RoHS Compliant
How to Evaluate Torque and Mounting Requirements
For a panel rotating around a horizontal axis, the gravitational moment changes with the panel angle. Engineers should account for panel mass and the distance from the hinge axis to its center of gravity, and the orientations in which the panel must remain stationary.
The simplest way to calculate torque is to multiply the weight of the lid by the distance of the panel measured from the hinge side and divide by 2, or:
Torque = 1/2 x (Weight of the Panel) x (Distance of Panel measured from the hinge side)
Compare that moment with the total usable friction torque of the specified hinges, allowing for friction torque hinge SFTH-02-5's ±1 kgf·cm tolerance. Consider additional operating forces including the weight of any handles or the shape of the panel.

Industrial Uses and Related Models
Potential applications include instrument housing lids, compact maintenance panels, electrical enclosure flaps, and other lightweight industrial access components, subject to engineering review.
For greater holding resistance, consider the SFTH-03-9 stainless steel torque hinge, rated at 7.8 lb·in (9 kgf·cm), but it has a larger footprint.

Stainless Steel Torque Hinge - SFTH-02-5 FAQs
What torque does the SFTH-02-5 provide?
The hinge provides 4.3 lb·in (5 kgf·cm) nominal friction torque per piece, with a ±1 kgf·cm tolerance.
Can the SFTH-02-5 friction torque hinge be adjusted?
No. It has a non-adjustable friction setting. Specify the appropriate hinge based on calculated panel loads and operating requirements.
What fasteners are needed for installation?
The SFTH-02-5 has five mounting holes and requires 3.5 mm or #6 screws. Fasteners are not included; verify screw suitability for the mounting material.
