"Rotary Connector: Customer Feedback" from the industrial machinery manufacturing industry/trading company.

There are no products with a large current and hollow structure that meet the company's requirements. We have ideas for new products, but there is no place to manufacture them. Please consult us first about what cannot be done!

We would like to share feedback from our customers regarding the rotary connectors developed and manufactured by Hisawa Giken. Company D, in the industrial machinery manufacturing sector, was struggling because there were no products that met their requirements for high current and hollow structure. After placing an order, they expressed, "The response to our requirements was quick, and the proposals were good." Our company starts with development. If there is something we cannot do, please consult with us first. 【Customer Feedback Summary】 ■ Company D, Industrial Machinery Manufacturing ■ Challenge: There were no products with high current and hollow structure. ■ Company C, Trading Company ■ Challenge: They had ideas for new products and consulted various places but were struggling to find a manufacturer. *For more details, please refer to the PDF document or feel free to contact us.

4-pole rotary connector

4-pole rotary connector

Mercury-free, this is our company's unique structure of a 10A x 4-pole rotary connector.

This is a mercury-free rotary connector (slip ring) with a new structure. Unlike conventional slip rings that conduct electricity through sliding, this product features a structure similar to roller bearings, allowing for rotational electrical connection through planetary motion. As a result, it generates less wear debris and achieves a long-lasting product with minimal noise.

Mercury-Free Rotary Connector 'GRC-1-250'

Mercury-Free Rotary Connector 'GRC-1-250'

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.

[Application-Specific Problem Solving Case] Hoop Plating Processing Equipment

[Application-Specific Problem Solving Case] Hoop Plating Processing Equipment

Long lifespan and maintenance-free! A case study proposing the mercury-free single-pole rotary connector GRC-1-250.

We would like to introduce our application-specific problem-solving case study: "Hoop Plating Processing Equipment." We faced the challenge of having used rotary connector products containing mercury, but due to environmental measures, we could no longer use products that contained mercury. In response, we proposed the mercury-free single-pole rotary connector GRC-1-250. Not only did we satisfy environmental concerns, but we also met performance and cost expectations, allowing for a replacement of the mercury-containing products. 【Case Overview】 ■Challenge - Due to environmental measures, products containing mercury could no longer be used. ■Result - By utilizing the expertise of a slip ring specialist manufacturer and employing a unique structure different from other companies, we were able to achieve performance equivalent to that of mercury products. Additionally, by offering a direct sales-only specification to users, we were able to keep product costs down, providing cost benefits as well. *For more details, please refer to the PDF document or feel free to contact us.
