InquiryAs Japan moves toward Society 5.0—the fusion of cyber and physical spaces—the industrial sector is undergoing a massive Digital Transformation (DX). Despite the rise of Ethernet-APL and Industrial Ethernet, the HART (Highway Addressable Remote Transducer) protocol remains the backbone of Japan's process industries, including oil refineries in Chiba, chemical plants in Kawasaki, and water treatment facilities in Hokkaido.
Japanese manufacturers are renowned for their pursuit of "Monozukuri" (excellence in manufacturing). However, many established plants still rely on 4-20mA analog loops. The challenge lies in extracting the hidden digital data from these loops without a complete infrastructure overhaul. This is where our high-performance HART Modems and Converters provide "Information Gain" by enabling:
Our commitment to the Japan market extends beyond manufacturing. We are developing the next generation of HART gateways that incorporate Edge Computing and Enhanced Cybersecurity. In the Japanese context, where "Trust" and "Zero Failure" are the standards, our products undergo rigorous stress testing to ensure compatibility with major Japanese PLC brands like Mitsubishi Electric (MELSEC), Yokogawa, and Omron.
Our roadmap includes the integration of:
Jiaxing Songmao Electronics Co., Ltd., established in 2007, operates at the heart of the global electronics supply chain. For our Japanese clients, we offer a unique blend of Supply Chain Resilience and Cost Efficiency. Our proximity to major shipping ports ensures rapid lead times to Kobe, Tokyo, and Fukuoka.
Every HART modem undergoes a 48-hour burn-in test and full protocol compliance verification before dispatch.
We provide OEM/ODM services tailored to specific Japanese industrial standards and branding requirements.
Stable supply chains even during global disruptions, ensuring your factory modernization projects stay on schedule.
Using SM100-M series collectors to monitor pressure and temperature transmitters at liquefied natural gas terminals in Nagoya.
Retrofitting legacy sensors with RS485 HART converters to feed data into digital twin models for process optimization.
Deploying GPRS/4G All-Netcom data collectors (SM626H-D) for remote leakage detection across municipal water networks.
Our modems utilize proprietary filtering circuits and optoelectronic isolation (up to 1500VDC) to ensure that the Bell 202 FSK signal remains pure even in the presence of large VFDs and heavy machinery common in Japanese manufacturing.
Yes, our SM100-C (III) and other USB interfaces use standard FTDI chipsets, ensuring plug-and-play compatibility with Windows 10/11 and full integration with PACTware, FieldCare, and Yokogawa PRM systems.
Absolutely. Our HART-to-Modbus collectors (like the 8-channel SM100-W) support up to 15 devices in a single loop, allowing for significant savings on cabling and I/O modules.
We strictly adhere to CE, FCC, and RoHS standards. For the Japan market, we can provide technical documentation to assist with local TELEC or MIC certification requirements for wireless-enabled devices.

A staple for field service engineers in the Japanese energy sector.
