The product catalog has been updated. The latest version is from October 2025.

We have started selling the 'KSR426W-A' as the successor to the waterproof remote control receiver KST426W's KSR426W and KSR426. The 'KSR426W-A' is a waterproof output unit equipped with four control outputs and four selectable output modes depending on the application. It supports the highly requested DC 24V, which is new for the successor to the KSR426W. Compared to the conventional receiver, the power supply voltage now accommodates DC 7-24V, and the antenna connector has been changed to the more common SMA-J. The 426MHz band waterproof remote control series for light industries has been enhanced for robustness and waterproofing, ensuring reliable long-distance communication through our developed wireless technology, making it safe for use in harsh outdoor environments. It can be utilized as a highly reliable telecommunication system for various industrial applications such as civil engineering, construction, vehicles, welfare, and agriculture. For details such as the selling price, please refer to the product page for KSR426W-A. *Please note that KSR426W and KSR426 have different antenna connector shapes, so the cables and antennas that can be used will differ. When ordering, please be sure to refer to the combination examples and make your purchase accordingly.

Significantly reduce the development man-hours for hardware and greatly shorten the time from development to deployment. It is designed to be ready for immediate use. This product is particularly suitable for prototyping in small lots. The software can be developed to match specific applications, allowing for detailed customization to specifications. There are two types: Dokodemo Demu and Dokodemo Demu Mini, each equipped with a compact model featuring a LoRa wireless module and an LTE model with LTE-M. Product names: DM-100, DM-200, DM-300, DM-400. For details such as sales prices, please refer to each product page.

The MLR-429 is a wireless module that focuses on serial communication, aiming for miniaturization and ease of integration. In addition to conventional FSK mode communication, it features a LoRa mode that enables ultra-long-range communication at a low bit rate. In LoRa mode, it achieves a communication distance of over 10 km in line of sight, despite having a low transmission power due to its excellent reception sensitivity. It connects to external microcontrollers or PCs via a UART interface, allowing for data transmission and device control using our unique command system developed in the industrial sector. It can be used for data transmission and telemetry applications. Product name: MLR-429 For details such as sales price, please refer to the MLR-429 product page.

We will start selling the UART interface communication module "LTM-1," which supports LTE Cat.M1, a cellular LPWA, from August 2024. The LTM-1 is compatible with LTE Cat.M1 and is equipped with the nRF9160 from Nordic Semiconductor. LTE-M supports best-effort communication using carrier lines.
