Waterproof wireless remote control for industrial applications born from customer requests, with 2 to 4 contacts (continuous control).

The KST2.4W and KSR2.4/KSR2.4RY are products born from customer requests. Our customers often use them for industrial applications, so we have enhanced their waterproofing and robustness to suit industrial use, and ensured reliability in communication by supporting a Hamming distance of 6. Additionally, a buzzer sounds according to the button pressed, and the link status can be confirmed via an LED. To allow multiple systems to operate in the same area, we have adopted our unique frequency hopping technology, enabling simultaneous operation of over 10 sets. The control units are compatible with 9V, 12V, and 24V systems, and the communication range is approximately 100 meters in line of sight. The product has obtained the Technical Compliance Mark and can be used without any licensing procedures. The term "light industry" is named with the assumption that it can be used in somewhat harsh environments as a general-purpose industrial product, targeting civil engineering, construction, vehicles, welfare, agriculture, and more. It is intended for applications requiring continuous control, such as operating a motor while a button is pressed. Wireless remote controls: KST2.4W-2 (2 buttons), KST2.4W-3 (3 buttons), KST2.4W-4 (4 buttons) Input unit: KST2.4S Control units (receivers): KSR2.4, KSR2.4RY (relay type)

As thinking of wireless technology, major solutions are remote controls, celler, bluetooth and WiFi. But there are so other solutions that, while fewer in number, are still necessary. Our one of the challenge is exploring them one by one. We forcase in the design, development, and quality control of wireless devices, including our main product, engine starters, as well as wireless control devices for security, medical, and industrial applications (industrial remote controls, telecontrols). We also have a local subsidiary in Munich, Germany, to serve as our sales base, where we design and develop wireless devices in compliance with the radio laws of various countries, such as Europe (CE maring), and introduce our products to markets around the world.
