Compact and lightweight (50g) for outdoor use with long-range detection (10m). It reliably detects people and vehicles as an obstacle sensor, and does not detect rain or snow.
Compared to existing ultrasonic sensors, the features of our sensor are: (1) It can be used outdoors and is not affected by rain or snow. (2) It is compact and lightweight (50g for the main unit) while also capable of long-distance detection (10m). (3) It has high sensitivity, resulting in good angular characteristics, making it less prone to malfunctions such as fluctuations in output values due to wind. (4) It is overwhelmingly low-cost (about half the price) compared to existing products with equivalent performance.

basic information
The principle of ultrasonic sensors involves applying a high voltage to a transducer to make it vibrate and generate sound waves (like a speaker). When the sound waves bounce back from an object and hit the transducer, a voltage is generated (like a microphone), allowing for time measurement. This time can be converted into voltage and current, enabling distance measurement, as the speed of sound is approximately 330 m/s. Each series includes two types: an analog output type for distance measurement and a digital (switching) output type for detecting the presence of an object within a set distance range. The analog output type is typically used for distance measurement, with a current output usually in the range of 4-20 mA. A common application is measuring the liquid level in tanks, and it is also referred to as a level sensor. Recently, there have been increasing examples of using analog output as an obstacle sensor. The digital output (ON/OFF) is mainly used as an obstacle sensor, particularly mounted on unmanned transport vehicles to prevent collisions with people or vehicles. It performs control functions such as deceleration and stopping.

Applications/Examples of results
For example, golf carts are now electric, and unlike the old engine types, they move silently (with a maximum speed of 20 km/h?). Moreover, during tee shots, they can drive automatically via remote control. Although they run on a designated path (using electromagnetic induction), if there are players on the path, it could lead to collisions and accidents. The OM5 series supplied by our company can detect up to 5 meters with two open collector outputs for both near and far detection. When it detects something at 5 meters, the cart slows down, and if it detects something within about 2.5 meters, it stops. In another example, two sensors can be placed a certain distance apart along the roadside to measure the speed of passing vehicles or the size of the vehicles. In the railway sector, there are applications where sensors detect when a train is entering a station, automatically turning on the monitor's display. There are countless applications for measurement, and I believe that unlike light, it is particularly advantageous because it is not affected by colors and can detect over a wide angle.
Company information
Sixteen years ago, we were established in Koriyama City, Fukushima Prefecture, as the general agent for a light sensor manufacturer located in Kyoto. We are primarily involved in the promotion of control light sensors used in factories in Fukushima, Yamagata, and Miyagi Prefectures. Due to certain circumstances, we began manufacturing ultrasonic sensors, which piqued our interest with their unique features not found in light sensors, leading us to attempt the import and sale of ultrasonic sensors from Europe and the United States. Eventually, we started our own development, and the first product we worked on was an ultrasonic sensor for measuring height. Throughout the development process, we increasingly recognized both the excitement and challenges, becoming more deeply engaged. As a result of developing sensors for long-distance detection that can be used outdoors, we are now confident that we have outstanding achievements in obstacle sensors, particularly for golf carts. Regardless of the quantity purchased, we quickly supply ultrasonic sensors that match our customers' requests (including prototypes), and in the event of any issues, we take responsibility until they are resolved. This is what defines us as ultrasonic artisans.
