lockbereik

Lockbereik is a compound term found in some German- and Dutch-language technical writings to denote the range or reach of a locking system. Because the term is not standardized, its precise meaning varies by domain, and it is often used as a shorthand rather than a formal specification.

In physical locking, lockbereik commonly refers to the actuation range—the spatial region within which a key, card, or mechanical actuation can reliably operate the lock. This can depend on the design of the mechanism, tolerances in the keyway, and the presence of auxiliary components such as levers or sensors. For example, a door lock with an extended actuator may have a larger actuation range than a compact lock, affecting how and where a credential must be presented.

In digital or electronic locks, lockbereik frequently describes the wireless or contactless unlocking range. This encompasses the distance at which a credential (such as a key fob, mobile device, or RFID tag) can initiate an unlock signal. Factors influencing this range include transmitter power, antenna quality, shielding, interference, and battery state. The concept is closely related to the effective range or operating range used in access-control documentation.

In security engineering, addressing lockbereik involves balancing convenience and risk: a longer range improves usability but may increase exposure to opportunistic attacks. Therefore, practitioners often prefer explicit terms such as actuation range, unlocking range, or effective range in formal specifications.

Overall, lockbereik is a contextual shorthand rather than a universally defined term, best replaced with precise measurements or domain-appropriate terminology in technical documents.
