We develop power and signal transmission systems that enable simultaneous transmission of a contactless power supply and signal transmission.

We develop sensors for various kinds of FA and mechatronics equipment, including contactless (wireless) power supplies for FA. We have developed a remote system that enables simultaneous transmission of a contactless power supply and signal transmission, and we support various related products. There is no restriction in the sensor selection and usage because of their adaptability to data signals of analog/digital signal sensors, CC-Link, and so on.

Sales Pitch

Wireless power supply system for automatic guided vehicles (AGV)
Overview of the system
Charging stations built at certain locations along driving lines allows for the recharging of batteries during operation. This greatly contributes to the automation of battery charging, improvement of factory productivity, and the saving of labor. We have added to our lineup a new specification of an unprecedented charging range of 600 W. You can choose the most optimal charging system from a wide range of variations. To give you enough time to consider the benefits of the wireless power supply system prior to its implementation, we provide charging simulations that show results in a specific numerical manner.
Very safe.
Since our wireless power supply system has no electrical contacts, no electric shock will occur even when touched by a person.

Very simple.
You do not need to link any connector. Just place the charging system and AGV face to face. Then charging will automatically start.

Very economical.
Our wireless power supply system will reduce the costs of operation and spare supplies.
For companies that have the following problems
- Electrode breakage caused by the start of AGV
- Heavy burden on workers caused by battery replacement
Starting up prototyping
Lean start-up
We provide various services, including the production of samples to examine the image of movement, prototype development for structure investigation, and final design for mass production, to meet the requests of customers who are interested in wireless power supply. We provide customers with a prototype of the wireless power supply in a short time based on the “lean start-up” action program that is focused on the improvement of efficiency. From a very early stage, we offer function confirmation and structure investigation of the wireless power supply system that you can use as the basis for market research.
Service characteristics
Since no one can imagine how an expanded world with a wireless power supply will look like, we will provide a staged startup to enable you to realize its effect immediately.

(1) Start-up prototyping: We make start-up prototypes with the minimum of requested functions in a short delivery time and at a low cost.

(2) Simulation: Before the prototyping, we perform simulations to confirm more detailed implementation effects and determine final shapes.

(3) Functional prototype: We make a new substrate and fabricate a sample wireless power supply assuming a state in which a wireless power supply has already been installed.

(4)  Mass production prototype: Based on the problems in functional prototyping, we make revised versions one by one towards mass production.
Application example
Bicycles for sharing
Carts for medical purposes
Electronic locks
and many others 










Other presentation

[Company strength]
1. Abundant experience with contactless power supplies: We have carried out research in the contactless (wireless) field and mass production technology for more than 20 years. We have realized many applications mainly regarding the automation of manufacturing processes and machine tools. (We have acquired patents, and have also applied for many other patents.)
2. OEM development and manufacturing technology: We have conducted consigned development and manufacturing regarding various control technologies, including the construction of contactless power supply technology.
3. R&D and manufacturing systems: We have facilities such as a radio-wave darkroom (for experiments with various signals and noise), mounters, laser processors, vending machines, ferrite core manufacturing devices, and automatic coil winders. We carry out integrated in-house planning, development, experiments, processing, and manufacturing. 

[Business description]
We develop, manufacture, and sell sensors for various kinds of FA and mechatronics equipment, including contactless power supplies for FA. We particularly support customers in automobile and machine tool related industries with various kinds of next-generation processing and mechanical automation.


[Strength of products/technologies]
1. Engineering and products that realize simultaneous transmission of a contactless power supply and signal transmission.
There are many products in the world that the realize one of these two functions. However, our remote system is the only product that realizes both functions.
2. Any types of sensors can be connected.
Our products can handle the sensors of analog/digital signals and data signals such as CC-Link. Our remote systems can be connected to the products of any manufacturer, so there are no restrictions on the selection and use of sensors.

[Representative's message]
We develop, manufacture, and sell remote systems. Our products are epoch-making transmission systems for power and signals that realize both a contactless power supply and signal transmission. The fact that there are no other products comparable to ours in this area is widely recognized by our customers. We have been providing innovative products to the market to support future automation technology, including sensors for FA, system equipment for FA, and FA-related components. Our corporate philosophy is “With Tomorrow Automation.” We hope to provide products that can make a deep impression on customers in a wide range of fields in addition to the FA-related market. 

[Company structure for market development/overseas expansion]
1. Organization for technical support 
We have established divisions in charge of product planning and technical support. This is to support customers with their technical issues and in cultivating new businesses. 
2. Organization for overseas expansion 
We have been a group company of the German sensor manufacturer Balluff, so we have abundant experience in global transactions and technical support to overseas entities. We work hard to support overseas customers and to participate in exhibitions overseas. This is done by making use of our staff who can support overseas business. 

[Market share/Ranking]
