We will be exhibiting at the "Mechanical Components Technology Exhibition" held at Intex Osaka from October 7 (Wednesday) to October 9 (Friday), 2026. This year, with the theme "NEXT STAGE - Challenges of 100-Year-Old Companies," we will showcase various components that are active in multiple fields, including transportation robots, semiconductor manufacturing equipment, retail, kitchen-related, construction machinery, and the delivery industry. The highlight of our exhibition will be the "Motor Lock." The "Motor Lock" possesses overwhelming power that electric locks do not have, while being an energy-saving product with low electricity consumption. Thanks to its energy-saving features, it not only contributes to CO2 reduction from an eco-friendly perspective but also helps in suppressing heat generation by optimizing the power-on time. If you have any concerns regarding component selection, please feel free to consult us at the exhibition venue. Additionally, our comprehensive catalog has been renewed for the first time in six years and is now available for shipping. It covers all catalog products, including new items, and consists of a substantial 1,264 pages. We invite you to visit our booth to check the actual operation and usability of our products. We will implement an exhibition method that allows for smooth loading and unloading. Please make use of it.

One-push locking & automatic pop-up unlocking with electric power The door is securely locked just by pushing it in (passive locking). When powered, the lock jumps up in the direction of the door opening, incorporating a "kick-out (push-out) function" that allows the door to be slightly pushed open by itself. There is no need to design or place separate springs or push-out pins. "Door rattling prevention" through holder effect Equipped with a standard holder mechanism that suppresses rattling (play) when closed. This contributes to maintaining airtightness, vibration resistance, quietness, and enhancing the overall premium feel of the product. Built-in micro switch (signal detection of open/close and locking state) Without needing to install separate detection sensors, the electric lock can output signals for open/close and locking states on its own. This prevents the hassle of sensor position adjustments and the complexity of wiring design. Significant reduction in the number of parts and design man-hours through unitization Consolidating five functions—"solenoid unlocking," "latch holding," "door pushing," "rattling absorption," and "state detection switch"—into one unit. This simultaneously simplifies mechanical design and saves space.

Ultra-thin design with a thickness of only 10mm (space-saving) Design advantage: It can be easily placed in confined spaces with limited clearance around the internal casing and doors. This minimizes dead space and maximizes the effective volume inside the storage box. Electric lock with automatic pop-out function Design advantage: The latch engages mechanically just by pushing the door, and when power (DC24V) is applied, the lock mechanism simultaneously pushes the door open (pop-out function). This pop-out action eliminates the need for handles or knobs on the surface of the casing, achieving a flat and stylish exterior design. Incorporation of a wobble prevention mechanism Design advantage: A dedicated holding holder is standardly equipped at the fitting part of the receiving seat (keeper). This suppresses unpleasant wobbling and misalignment of gaps in the door when locked, enhancing the overall rigidity and quality feel of the product.

■Labor-saving (One-touch installation) The push-in type allows for simplified and efficient installation work. ■SEMI standard compliance It complies with SEMI S8-0218 (Section 6.8.1) "Hook grip type handle." With a large opening, it excels in safety and operability, making it suitable for introduction into semiconductor manufacturing equipment. ■High flame retardancy It uses flame-retardant synthetic resin equivalent to UL94V-0, ensuring safety. ■User-friendly design The gripping area is rounded (R shape) and designed to be deeper, making it easy to grip firmly and reducing hand strain during work.

This is a flat hinge made entirely of SUS316. Since all parts from the wing to the shaft are made of SUS316, it excels in "corrosion resistance" and "chemical resistance" compared to SUS304. Additionally, the "R shape" of the wing part makes it difficult for dirt and cleaning solutions to accumulate in the corners, and even if they do adhere, the properties of SUS316 prevent rust from forming. It is ideal for use in ships, marine structures, and food and pharmaceutical factories.

■Reliable locking and prevention of rattling Due to the long stroke, even if there is some deviation in the door's closure or misalignment due to aging, it can reach the keeper deeply and securely, ensuring reliable locking. ■Holding power at the stroke end The long operating distance allows the locking pin to enter deeply, increasing the physical holding power against prying and vibrations. ■Improved design flexibility Due to the structure of the housing, it allows for flexible design when the locking mechanism needs to be placed deep within the door or when a wider range of motion is desired. ■Residual magnetism countermeasures When the power is turned off, the latch can return instantly to its original position without getting stuck. This prevents malfunctions and ensures stable operation.
