When controlling from a PC, relay functionality can also be utilized, allowing control of contact information from locations several kilometers away. The relay station of the MU-3-1216 operates solely with initial device setup and power supply. To operate, pairing settings between the MU3-IN8-1216 and MU3-OUT8-1216 are required initially. This radio device allows the antenna to be installed in a location with good radio wave conditions using an extension cable. 【Features】 ■ Continuous communication of 8 contact information ■ Easy embedded wiring via terminal block ■ High isolation with photo MOS relays

The "SLR-429M" is an embedded wireless module designed for ease of use. In addition to the LoRa mode, which enables ultra-long-range communication at low bit rates, it also features a conventional FSK mode. It achieves LPWA via LoRa with a completely proprietary protocol in the 429MHz band, which is designed solely for circuit applications. The 429MHz band has superior diffraction characteristics compared to the 920MHz band, allowing for stable communication in various environments such as indoors, mountainous areas, along rivers, and underground. It connects to external microcontrollers or PCs via a UART interface. This is a specific low-power wireless module that requires no license and incurs no communication fees. 【Features】 ■ Communication distance: over 10km line of sight ■ Communication speed: 245bps ■ Capable of communication with up to 8 contact points ■ Superior diffraction characteristics compared to the 920MHz band *You can purchase directly from the related links. Orders starting from one unit are also welcome!

The KST2.4W and KSR2.4/KSR2.4RY are wireless remote controls developed in response to customer requests. Our customers often use them for industrial applications, so we have enhanced their waterproofing and robustness to suit industrial use, while ensuring they are easy to hold and maintain a communication reliability with a Hamming distance of 6. 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, with a communication range of approximately 100 meters in line of sight. The product has obtained the Technical Conformity 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.
