SMA Magnetic Sensor Board
SMA Magnetic Sensor Board
The 1 channel SMA sensor is a vehicle detector using electromagnetic loops. It is fitted with a microprocessor and has been designed for access and traffic flow controls. The operating principle involves measuring the inductance variation in the magnetic loop caused when a vehicle passes over it. The SMA sensor comes complete with an 11 pin support/terminal block for connection to the loops and the 12 or 14V ac/dc power supply.
