On September 11, 2025, AC Tasarim, a cable blade manufacturer, and our company signed a sales agency agreement for Japan. This was also announced in the company's press release and on social media. Founded in Turkey in 2003, AC Tasarim manufactures flexible EMI cable shields (copper braid), polyester braid, meta-aramid braid (Nomex cable sleeves), flat copper braid busbars/ground braids, all AA59569-coded copper braids, and released AeroBraid in 2025, the world's lightest EMI braid. All manufactured copper braids are certified to military standards. AC Tasarim products hold key certifications including VDE/VG certification, German Federal Armed Forces certification, NATO NSN coding, AS9100 quality certification, and JOSCAR certification. Cable braids and EMI shielding products, essential for wire harnesses in the aerospace and defense industries, are becoming increasingly difficult to source as demand rises. TC Tasarim products are stocked by manufacturers and distributors to ensure quick response times.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

The "HM-S6" is an embedded park sensor that detects vehicles through changes in magnetic flux and can respond to various situations from passing to stationary. It can be used for the opening and closing of the input doors at waste treatment plants, as well as for gates where vehicles pass and in outdoor parking applications. It can also be installed on rebar and steel plates. 【Features】 - Resistant to the effects of natural environments such as rain, snow, temperature changes, and geomagnetism. - Protection rating IP68 reduces the risk of water ingress. - Ten times the load capacity compared to conventional embedded park sensors (according to our comparison). - Can distinguish between vehicles even when they pass continuously, one by one. - Can be installed on rebar and steel plates. *For more details, please refer to the PDF document or feel free to contact us.

The "CCS2" is a ceiling-mounted vehicle counting sensor that employs an infrared reflection method. It can detect vehicles in both directions with just one unit, accurately counting vehicles even during traffic jams or when vehicles pass each other. Additionally, this product can be used not only for vehicle counting but also as a sensor for departure warnings. Furthermore, by using a separately sold dedicated remote control, it is easy to reset the sensor alone, switch the counting direction, and change the patterns of the departure warning timer. 【Features】 ■ Angle adjustment is possible up to ±5° ■ Can be installed in locations with high ceilings up to 4m ■ Detection area consists of 40 spots, allowing for wide-range detection ■ The display LEDs are color-coded by direction, making operation confirmation easy.
