We have released materials with test data. "Mercury-Free Rotary Connector"

Exclusive to direct sales, therefore low price. Achieving top-class low torque in the industry. Materials with test data provided.

The "GRC-1-250" is a one-pole type rotary connector that uses liquid gallium alloy instead of mercury and is suitable for high-temperature environments (up to 80°C). It can be installed in both vertical and horizontal orientations, making it a viable replacement for existing rotary connectors. With low torque, low noise, and stable resistance values, it is effective for various applications. It complies with the RoHS2 directive and can be disposed of as regular industrial waste, contributing to reduced disposal costs. 【Features】 ■ Made in Japan ■ Compliant with RoHS2 directive ■ Low torque ■ High current ■ Low noise and low contact resistance (below 1mΩ) due to no contact points used ■ Usable in high-temperature environments compared to mercury (4-80°C) ■ Can be processed as regular industrial waste *We are currently providing materials that include test data on electrical characteristics. You can view them via PDF download. Please feel free to contact us for inquiries.

Essential for powering rotating bodies: that is the slip ring system (collecting device). In recent years, the advancement of various industrial machines has been truly remarkable, following a path of increasing complexity and sophistication. The slip ring system plays a crucial role in alleviating these complex functions. Based on years of experience and technology, our company continues to make unceasing progress to establish greater trust in response to the needs of our users. <Case Studies for Problem Solving> - Unable to use mercury due to environmental considerations - Want to stabilize the reading of thermocouple signals - High voltage, but want to minimize the size of the housing as much as possible - Want to use a servo motor through a slip ring, etc.

The "Hotron Non-Contact Switch" allows you to open and close doors without directly touching door knobs or switches, making it hygienic! You can choose from two types: the "Hand Wave Sensor," which only requires you to wave your hand, and the "Foot Switch," which only requires you to place your foot in front of it. It reduces the risk of virus and bacteria transmission in places where hygiene is a concern, such as food factories, restaurants, hospitals, and nursing facilities. 【Features】 ○ Reduces the risk of virus transmission by allowing door operation without contact ○ A wide variety of options to choose from based on application and location ○ Ideal for places where hygiene is a priority, such as food factories and medical facilities ○ Prevents unnecessary detection due to the switch mechanism 【Product Lineup】 ■ Hand Wave Sensor Series ○ Exposed waterproof type, front, down, and side-facing types "PF-R5" ○ Exposed type, front-facing type "PF-R1" ○ Embedded type, front-facing type "PF-U2" ○ Exposed type, downward wide type "PF-R4" ■ Foot Switch Series ○ Slim type with wide opening, vertical beam type "PF-01S" ○ Slim type with wide opening, horizontal beam type "PF-03S" ○ Standard type, horizontal beam type "PF-05" ◎ For more details, please download the catalog or contact us.

Do you have any concerns or requests regarding wired bed exit sensors? × Tangling and tripping of wired cables × Cable disconnection or damage × Worry about forgetting to turn on the switch after temporarily stopping the sensor. × Want to be notified of bed exit even from a location away from the nurse call outlet. Such concerns can be resolved simply by connecting to a wireless set linked to the nurse call system! Our nurse call linked wireless set allows you to connect bed exit sensors like "Ugo-kun," "Foldable Thin Matta-kun," "Ayumi-chan," and "Just Place Pole-kun" to transmitters and receivers, reducing wiring around the bed, alleviating concerns about tripping and falling due to cables, and contributing to a tidier work environment. Furthermore, it enables the use of bed exit sensors even from locations away from the nurse call outlet, allowing for more flexible equipment placement.

Hotron's vehicle detection sensors allow you to search for products that meet your needs in three categories: "Purpose of Use," "Location of Use," and "Product List." The sensors detect the passage of vehicles, alerting you with rotating lights or switching the display of parking availability. They manage vehicle presence, full parking, and exit warnings in parking lots, contributing to safe driving and smooth operational management within the parking area. They are used in various settings, from coin-operated parking to large-scale parking lots.

Various greases are used for the lubrication of molds and machine parts, but in high-temperature environments, the performance of standard lithium greases significantly decreases, leading to issues such as seizure and galling. So, how should one choose "high-temperature greases"? First, the heat resistance temperature should be noted. Typical lithium-based greases have a limit of around 200°C, but in mold environments, conditions can reach 400°C to 800°C. In such cases, high-temperature greases that use heat-resistant additives or special base oils are essential. Second, oxidation stability is also important. When the oil oxidizes due to rising temperatures, the lubricating film is lost, and component wear progresses rapidly. Third, the initial break-in performance should not be overlooked. The ability to form a smooth film during startup at high temperatures can greatly affect the lifespan. For example, the "Golden Grease Series" can handle mold environments up to 800°C due to its hybrid design of inorganic and organic components. It allows for lubrication, release, and rust prevention all at once, leading to more efficient mold maintenance. In workplaces struggling with high-temperature environments, choosing such specialized greases can achieve both increased production efficiency and cost reduction.

The 2025 Osaka-Kansai Expo will feature the theme "Designing a Future Society Where Life Shines," showcasing numerous cutting-edge visual productions and experiential exhibits. Central to creating immersive video experiences that strongly engage visitors is projector technology. Supporting this performance at its core are optical thin films (optical filters) applied to lenses and optical components. As brightness and resolution increase, the quality of optical thin films directly impacts the clarity, color reproduction, and durability of the images. The "amazingness" of the video technology at this Kansai Expo has evolved beyond merely providing visual information to becoming a means of reconstructing the space itself. In particular, in the field known as "immersive video," stimulating multiple senses such as sight, hearing, and touch allows viewers to be drawn into the narrative, blurring the boundaries between reality and the virtual experience. 【1】The Power of Video Supporting Immersive Experiences 【2】What is a Three-Sided Screen? - The Key to Video Production Supported by Projectors 【3】What are the Representative Pavilions Where You Can Actually See a Three-Sided Screen at the Expo? 【4】What Optical Thin Films are Necessary for Projectors to Achieve a Three-Sided Screen? 【5】What is the Future Where Three-Sided Screens and Projectors are Introduced into Homes?
