Came SMA Single-channel induction loop detector

CAME SMA 1-channel induction loop detector

FUNCTIONS

• vehicle detection for gates, barriers
• parking and traffic control
  

SMA is a single-channel vehicle detector operating at 24 V AC-DC. Recommended where there is a need for access control and traffic supervision vehicles.

The principle of operation is based on measuring changes in the magnetic loop induction; the vehicle passing over the magnetic loop leads to a lower value induction which is read and measured by the sensor. Change detection induction leads to activation of the relay connected to the devices external.

The detector is equipped with an LCD display and two buttons, thanks to which we can program detector functions and parameters.
Faults and error codes will be shown on the display.
LED signaling ensures continuous monitoring of the detector.
