VD-108B
Single Channel Vehicle Loop Detector
Industrial design, super anti-interference ability and stability;
Support automatic detection function if coil is fault;
Can cooperate with barrier to achieve automatic close function when car leave.
VD108B is used for wherever vehicles have to be detected, for example for monitoring and safe-guarding
access ways or for counting vehicles. The output signal can be used for controlling door and gate drive
mechanisms, operating barriers, controlling traffic light systems or activating card dispensers in parking lots.
VD108B only have one TTL - level output, which is unlimited.
