Adjustable Torque Position Control POM Hinge MH200-4001

The Adjustable Friction Hinge features a free-stop positioning mechanism that allows doors, lids, and panels to remain at the desired opening angle. An integrated adjustment screw enables the holding resistance to be adjusted according to application requirements.

With a 160° opening angle, compact construction, and four-hole surface mounting, this hinge is suitable for industrial equipment covers, access panels, electrical enclosures, and other applications requiring controlled positioning.

Max Torque（small one)：0.7 N·m
Max Torque(big one)：2.5 N·m

This hinge is widely used across industrial equipment and everyday hardware where controlled opening and arbitrary positioning are required:
• Electrical Cabinets & Enclosures: Perfect for the access doors, control panels, and transparent viewing windows of electrical boxes and automation equipment.
• Medical & Laboratory Instruments: Used on protective covers and flip-up lids for testing devices, allowing technicians to keep the guard open hands-free during operations.
• Industrial Machinery Shells: Ideal for maintenance hatches, safety guards, and operation panels that need to remain securely propped open during servicing.
• Marine & Outdoor Equipment: Due to its superior rust and weather resistance, it is highly suitable for boat storage hatches, marine electronics boxes, and outdoor telecommunication enclosures.
• Specialty Storage & Toolboxes: Applied to heavy-duty plastic cases, equipment transport boxes, and automotive storage consoles to provide a premium, dampened opening experience.

How to Evaluate Your Torque Requirements？
You can preliminarily calculate the total torque required for your lid, door, or panel using the following simple formula:
(text{Required Total Torque (N·m)}=text{Panel Weight (kg)}times 9.8times text{Distance from the Hinge Axis to the Center of Gravity (m)})
Example:
For a horizontally opening lid weighing 1 kg, with a distance of 0.15 m from its center of gravity to the hinge axis, the resulting gravitational torque is approximately (1 times 9.8 times 0.15 approx 1.47text{ N·m}).
In this scenario, choosing the Large Size hinge (with a maximum torque of 2.5 N·m) will perfectly allow you to hold the lid stable at any angle by tightening the adjustment screw
