Products/Services

  • Programmable radio unit

    Programmable radio unit(0)

    Significantly reduce the development man-hours for hardware and greatly shorten the time from development to deployment. It has been designed for immediate use. This product is particularly suitable for prototyping in small lots. The software can be developed according to the application, allowing for customization down to the details of the specifications. There are two types: "Doko Demo Demu" and "Doko Demo Demu Mini," each equipped with a special small model featuring a LoRa wireless module and an LTE model equipped with LTE-M.

  • Serial data communication

    Serial data communication(0)

    We use a simple, proprietary command that allows for the communication of serial data.

  • Ultra-long-distance communication

    Ultra-long-distance communication(0)

    Semtech's LoRa technology enables communication over distances of 1 to several kilometers with low power consumption. Unique command control allows for the transmission and reception of customer data as well as device control. The SLR-429M has eight I/O ports, allowing for contact control. The MLR-429 is a wireless module that focuses on serial communication, is more compact, and is designed for easier integration.

  • MU Series (Serial Data Communication)

    MU Series (Serial Data Communication)(0)

    The MU series is a specific low-power wireless modem that enables stable serial data communication through our proprietary command control. The MU-3 is a high-performance wireless modem composed of discrete components, available in the 429 MHz and 1216 MHz bands. The MU-4 is a wireless modem based on a single-chip wireless IC (RFIC), achieving miniaturization and cost reduction compared to the MU-3. The MU series in the same frequency band has command and communication compatibility.

  • Contact communication

    Contact communication(0)

    You can transmit contact information wirelessly. The products include trigger-type products that notify you of ON/OFF switching and alarms, as well as types that allow for continuous (momentary) control while pressed. There are wireless remote control types housed in enclosures and embedded wireless module types.

  • Light Industry Remote Control

    Light Industry Remote Control(0)

    To ensure safe use in harsh environments such as outdoor work, we have enhanced the robustness and waterproofing of our wireless remote controls, enabling reliable long-distance communication developed through our wireless technology. Please utilize it as a highly reliable telecommunication system for various industrial applications, including civil engineering, construction, vehicles, welfare, and agriculture. There are options available in the 426 MHz band (ON/OFF switching) and the 2.4 GHz band (continuous control and momentary).

  • Switching ON/OFF of the contact(0)

    Among wireless remote controls, devices operating in the 315MHz and 426MHz bands can be used for switching ON/OFF. Since transmission occurs only during switch operation, even a small battery can be used for a long time.

  • Contact continuous operation

    Contact continuous operation(0)

    Among wireless remote controls, devices operating in the 2.4GHz band, 429MHz band, and 1216MHz band can be used for applications such as inching operations, where contacts are controlled continuously. Communication (link) occurs regardless of whether contact operation is present or not. Products in the 2.4GHz band can confirm the LINK status on both the input and output sides. Since it is continuous communication, the principle is that communication occurs between one input device and one control device.

  • Wireless Audio (Analog)(0)

    Analog audio wireless module compatible with B-type wireless microphones in the 800MHz band, supporting frequencies B11 to B61.

  • 315 MHz band

    315 MHz band(0)

    Wireless devices in the 315MHz band comply with ARIB STD-T93 and can perform ON/OFF operations for relatively short-range connections of about 50 meters. Multiple remote controls can operate a single control device, or one remote control can operate multiple control devices.

  • 426 MHz band

    426 MHz band(0)

    Radio equipment in the 426MHz band complies with ARIB STD-T67 and can perform ON/OFF operations at a distance of approximately 200 to 500 meters. Multiple remote controls can operate a single control device, or one remote control can operate multiple control devices. Broadly speaking, there are the KST426W/KSR426(W) light industrial remote controls and the CDT/WT/WR series.

  • 429MHz and 1216MHz bands(0)

    Radio equipment in the 429MHz and 1216MHz bands complies with ARIB STD-T67 and can perform serial communication or continuous contact control over distances of approximately 1,000 meters. The SLR-429M adopts Semtech's LoRa technology, allowing for serial communication over several kilometers despite being a specific low-power radio device.

  • 2.4GHz band

    2.4GHz band(0)

    Wireless devices in the 2.4GHz band comply with ARIB STD-T66 and can control serial data or continuous contacts. The KST/KSR series and NT/NR series can control continuous contacts in a 1:1 ratio, and frequency hopping allows multiple sets of products to be used in one area. STD-503 is a wireless module that uses the 2.4GHz band for serial data transmission, and by adopting DSSS and true diversity methods, it enables communication over approximately 300 meters in line of sight.

  • 4G(Cat.M1/LTE-M)(0)
