TC-CK1-VMS INTERSECTOR™ Microwave Vehicle Motion Sensor

The TC-CK1-VMS INTERSECTOR™ is a microwave-based radar motion sensor used for intersection control. The unit interfaces with a traffic-control cabinet, and outputs signals when vehicles are present in user-defined zones. Zones are created using an X-Y coordinate system, and operation is verified and optimized using a laptop and web browser as part of the installation process.
The TC-CK1-VMS allows users to create up to 8 detection zones and assign vehicle motion in these zones to up to 8 outputs to the control cabinet. Detection zones can be created to a maximum distance of 600 feet from the sensor itself.
Interface boards are available for the TC-CK1-VMS which are compatible with both NEMA, 170, 179, and 2070 cabinets. For each sensor, one interface board is required in order to communicate with the control cabinet. Three interface boards are available. The TCIB-2.1 provides 2 outputs and uses a single slot in the cabinet. The TCIB-4.1 provides 4 outputs and uses a single slot, and TCIB-4.2 provides 4 outputs and utilizes two slots in the cabinet.
