Core CAME Loop Detector Models

Key Features

• Precision Tuning: Both models feature multi-level sensitivity adjustments (typically 9 levels), allowing you to fine-tune detection so the system ignores small metal objects while reliably catching cars, trucks, or trailers.

• Frequency Selection: Multiple selectable operating frequencies allow you to install adjacent loops without signal interference (cross-talk).

• Advanced Logic: Includes features like:

  • Automatic Sensitivity Boost (ASB): Helps detect high-bed vehicles or those with drawbars.

  • Time Functions: Supports switch-on/off delays and “presence” modes where the signal stays active as long as the vehicle is over the loop.

• Ease of Installation: DIN rail mounting makes them standard for control cabinet integration. They feature clear LCD displays and configuration buttons for quick setup.

• Fail-Safe/Fail-Secure: Options available to ensure your gate remains secure or opens automatically in the event of a power failure or loop fault.

How They Work

1. Inductive Loop: A copper wire is installed beneath the road surface (usually in a rectangular “saw-cut” or buried in a pipe/duct).

2. Magnetic Field: The CAME controller sends electricity through the loop, creating a localized magnetic field.

3. Detection: When a large metal object (your vehicle) enters this field, it changes the inductance (the “resonant frequency”) of the loop.

4. Signal: The controller senses this change and triggers a relay, sending a signal to your gate’s control board to either open the gate or hold it open for safety.
