Prevention of minor accidents

Someone is behind the door and collides with him/her the moment you open the door ... it's a minor accident in everyday life, but we want to avoid it as much as possible. So, an office supplies company King Jim has released a wireless type of light with a motion sensor that lets you know when someone is on the other side of the door and prevents collisions. The price is 15,400 yen (tax included).

It's a set of two, and when you mount the door with these, the sensors detect people in front of the door and let you know by flashing lights and a buzzer. The ranges covered by the sensors are about 120 degrees horizontally and about 110 degrees vertically. You can choose the buzzer volume from three levels.


Originally King Jim has been selling this wired version since June 2017, and has now released this wireless type. You can fix these to the door with the magnets on the main body, screws, and double-sided tape. Also, you can use them in single mode instead of in pairs. For example, if you fix them at dangerous places, you can alert people passing nearby. Each of these size is 140mm x 75mm x 105mm and weighs about 300g (excluding batteries). They work on four AA alkaline batteries for about two years. (When the sensor detects 30 times a day)
