Magnetic Decoupling Kinematics
Standard thumbturn cylinders maintain a mechanical connection between interior and exterior plugs. Magnetic Coupler Cylinders introduce a contactless magnetic clutch.
Kinetic Isolation
- Magnetic Drive: Rotational torque is transmitted across a magnetic gap via permanent Neodymium couplers.
- Zero Impact Propagation: When an external bump key is struck, the mechanical impact cannot propagate across the magnetic gap, completely neutralizing lock bumping.
Frequently Asked Engineering & Selection Questions
Q1: How does a magnetic coupler thumbturn stop lock bumping?
The interior thumbturn and exterior key are separated by a magnetic clutch that prevents hammer shock waves from traveling between them.
