A detent hinge is a positioning hinge that incorporates predefined stop positions using mechanical indexing. Unlike continuous-motion hinges, a detent hinge provides distinct “click” or “stop” points that hold a panel, lid, or display at specific angles.
This page explains what detent hinges are, how they work, key design considerations, typical applications, and how to determine whether a detent hinge is the right solution for your product.
What Is a Detent Hinge?
A detent hinge is a hinge mechanism designed to hold an assembly at fixed, repeatable angles using mechanical detents. These detents create tactile stop points that prevent the hinge from moving freely between positions.
How a Detent Hinge Works
A detent hinge works by combining rotational motion with mechanical indexing features inside the hinge assembly. As the hinge rotates, internal components engage at predetermined positions, creating a holding force that resists further movement until sufficient force is applied.
Detent Hinge vs Friction Hinge
A detent hinge provides discrete stop positions, holding the assembly only at specific angles. Movement between positions is intentional and often accompanied by tactile feedback.
A friction hinge, by contrast, provides continuous resistance throughout its rotation range and can hold position at virtually any angle without defined stops.
In General Selection Guide
- Choose a detent hinge when fixed positions and repeatability are required
- Choose a friction hinge when smooth, infinite positioning is preferred
Key Design Considerations for Detent Hinges
Detent Position and Angle Definition
Determine the exact stop angles required for product usability and functional positioning.
Detent Torque and Holding Force
Ensure sufficient holding torque to maintain stable positioning without excessive operating force.
Wear and Lifecycle Performance
Evaluate durability, material wear resistance, and lifecycle expectations for repeated engagement.
Typical Applications of Detent Hinges
Consumer Electronics
Used in adjustable stands, foldable devices, and display positioning mechanisms requiring repeatable angles.
Automotive Interiors
Applied in console lids, armrests, and display modules requiring fixed open positions.
Industrial Equipment
Control panels, access doors, and testing equipment where defined stop points improve usability.
Furniture and Appliances
Used in adjustable shelves, foldable components, and appliance lids with fixed open positions.
