Icoms - Model TMA-122 -All-in-one Microwave Detector for Traffic light Management
he TMA-122 is an all-in-one microwave detector for traffic light management. It replaces the approach loop and the presence loop at the stop line. The TMA-122 detects approaching vehicles as well as stopped vehicles at the stop line. It also triggers the dry contact at each passing vehicle to enable vehcile counting.

A reduction in costs on:
- Civil engineering budget
- Security budget
- Personnel intervention budget
The TMA-122 detects vehicles approaching the stop line from a distance of up to 60 m. Two relays are activated: the first relay is activated when a vehicle is moving in an adjustable area 20 or 60 m in front of the stop line. The second relay is activated when a vehicle is moving or stopping in an (adjustable) area of 10 m in front of the stop line. The “stop line” relay is maintained, within a preset time limit, until the vehicle is restarted. This relay is triggered for each vehicle crossing the stop line. Therefore, the information transmitted to the controller can be easily converted into a vehicle count. If a vehicle does not start when the light turns green, the automatic control system is thus informed of a possible congestion of the intersection.
