SANKO Ultrasonic Sensors to Prevent Contact with Heavy Machinery such as Trucks and Forklifts New, unused. Opened for inspection, no issues found. I bought this to install on my truck, but the 6m rear cable wasn't long enough, so I'm selling it. It should reach on medium-sized vehicles. SANKO's website sells 6m extension cables separately, so you can buy two to make it 12m and install it. I will ship it in the original box, which has some crushed corners. Purchase price was 24,800 yen. This heavy machinery contact prevention device uses four sensors to monitor the vehicle's surroundings, supporting the prevention of backing accidents and overhead contact accidents. No matter how carefully you drive, unexpected accidents can happen. The rear, which is difficult to see, is particularly prone to accidents. The safety sensor comes standard with four sensors, displaying the distance to the object on the monitor. An alarm sounds when you get too close. It supports 24V for large trucks and forklifts.
