Adopting gold plating to achieve high-reliability contacts and improved corrosion resistance.
AquaS Co., Ltd. is the official domestic distributor of Fischer Elektronik, a leading manufacturer of heat sinks and PCB connectors in Europe. 1. High reliability and low contact resistance - Utilizes gold plating (Ni + 0.75µm Au) on internal springs - Resistant to oxidation, maintaining stable contact resistance even with long-term use - Suitable for microcurrent and signal applications 2. Excellent mechanical durability - Ensures high elasticity and resilience with CuBe (copper beryllium) alloy springs - Contact pressure does not easily decrease even with repeated insertion and removal - Insertion force / extraction force is appropriate (1.8 N / 1.4 N), providing good workability 3. Wide pin compatibility - Compatible with both square and round pins Square pins: □0.22×0.25 to □0.40×0.55 mm Round pins: Ø0.4 to 0.56 mm

Company information
Our company has celebrated its 70th anniversary as a paper trading company. In addition to paper, we also handle packaging materials based on flexible packaging. We have also focused on the sale of LED lighting and have started selling several original products. We offer not only standard LED lighting but also high color rendering LED lighting, LED base lighting for hospitals, and high ceiling LED lighting that can be used in harsh environments such as factories and warehouses. In recent years, we became the first distributor in Japan for ICWUSA, an American monitor arm manufacturer. Known for its robust construction designed for professional use, it stands out in terms of originality compared to other products. We have actual units on display in our showroom on the first floor of our headquarters. We invite you to visit us and experience them firsthand.
