Locator for revolving door, has permanent magnet firmly connected to housing of ferromagnetic cam plate, and magneto resistive component arranged at specific distance to axis of drives of door
摘要
<p>The locator has a magneto resistive component (2) arranged at a specific distance to an axis of drives of a revolving door. An output signal of the component indicates a gap or a gap variation between a peripheral edge of a ferromagnetic cam plate (3) and the component. A permanent magnet (1) is arranged at a specific distance to a side of the component. The magnet is firmly connected to a housing of the drives.</p>
