Easy continuity check with just a touch of your finger.

The finger touch sensor NMT64B is an optional product for harness testers that enables continuity testing by touching the conductor of a cable with your finger. It utilizes the induced current received by the human body to confirm the continuity of the conductor touched by the finger. It can be connected to all harness testers sold by Nack Corporation that feature a search function. Currently, in the inspection field of wire harnesses, testing of one-sided cut cables (one side unprocessed and untreated) is difficult with probes, posing challenges for continuity testing operations. This product allows for continuity testing simply by touching the end of a one-sided cut cable with your finger, significantly improving work efficiency and greatly reducing inspection time. In addition to one-sided cut cables, it can be utilized for various applications such as navigation during connector housing and wiring work in distribution boards.

Electrical inspections are invisible. Ensure the inspection results are clearly visualized with marks.

Marking provides further "assurance" and "trust" in inspections. The automatic dot marking machine, Smart Marker NMPEN05, can automatically mark inspected products such as harnesses, cables, circuit boards, and connectors. With flexible installation accuracy and a compact design, it helps in process management, preventing the mixing of defective products, and improving quality. It supports reliable product shipping with inspection marks made by pens or stamps. 【Preventing the outflow of defective products at a low cost】 Marking is highly effective for preventing mixing errors and managing products before and after shipping. In the unlikely event that a mixing error occurs, having a mark makes it easy to identify the issue. The NMPEN series allows for low-cost automatic marking without relying on human hands. 【Soft movements like those made by a person】 The dot marking action, powered by the latest compact motor, moves gently and firmly leaves a mark, resembling the action of a person marking. It features a mechanism that causes minimal damage to both the marking target and the pen tip, unlike traditional solenoid types. 【Flexible installation】 The main unit can be fixed at any angle with a powerful magnet.

Metal 3D printers can create complex shapes and integrated structures, three-dimensional freeform water channels, lattice and porous structures, and hybrid structures, which are extremely difficult to achieve with conventional processing methods and technologies. This enables the creation of innovative die-casting molds, cost reduction and quality enhancement, short-term prototyping and manufacturing, dramatic reductions in the number of parts, weight reduction, significant decreases in manufacturing processes and workforce, and prolonged mold life. In this seminar, advanced users J.3D and Castec, who boast top-level technology in die-casting mold production using metal 3D printers in Japan, will explain in an easy-to-understand manner the specific molding technologies and examples of high-functionality and high-quality die-casting molds, core pins and inserts for die-casting molds, and low-cost molds produced using EOS-manufactured metal 3D printers, while sharing success and failure stories that suppress and prevent various defects and troubles associated with traditional methods. Additionally, we will introduce the much-discussed Gigacast, which is gaining attention in the United States and China. Recently, the production of molds using metal 3D printers has surged due to the retirement of veteran skilled workers. [Currently, the course fee is half price.
