The CAS-4RF is the most advanced commercial grade sonar system on the market today.
The CAS-4RF is a heavy duty vehicle reversing system specifically designed for commercial vehicles. It is equipped with stainless steel sensors and a heavy duty weatherproof control box which can withstand harsh weather conditions without any problems. The system “WARNS” the driver or operator with a “beeping” sound indicating potential obstacles are at the rear of the vehicle and then a clear voice “TELLS” the operator the countdown of the remaining distance in feet as the vehicle reverses. The device is activated when the driver puts the vehicle into reverse. Acoustic sensors installed at the rear of the vehicle will transmit a modulated beam signal that is capable of seeing through fog, rain, smoke and snow in any kind of weather, day or night. When the signal strikes a solid object, it bounces back to the sensor and instantaneously sends a detecting signal to the microprocessor.
BLIND AREA ALERTING:
As with all sensing systems there are blind areas in the sensing patterns due to the cone or triangular nature in the way the sonar pulse is emitted. Whenever an object moves from a covered area and into one of these blind areas a special warning alert message and a very loud tone “OBJECT IN BLIND AREA” will be transmitted twice or until the operator takes the vehicle out of reverse. This is especially helpful for detecting moving objects such as a pedestrian, an animal, a forklift or other moving vehicles that may be behind your vehicle and in harm’s way.
The typical performance detecting pattern for the follow object types are:
OBJECT EFFECTIVE DISTANCE
Concrete Wall 9 to 12 feet
Vehicles 8 to 9 feet
Pedestrian 5 to 6 feet
Post - 3 ft tall, 3 in diameter 3 to 5 feet
