Import Analog Linear Coupling — Buy in wholesale FOB from Supplier in China

The Analog Linear Optical Coupling from Nanyang Senba Optical & Electronic Co., Ltd. is a photoelectric component that uses a CdS photoresistor and LED semiconductor to convert input current into variable resistance. The device delivers pure resistor, non-polarity output with a wide analog linear resistance range, low on resistance, and high off resistance. Its input-to-output isolation minimizes distortion, making it suitable for both DC and AC applications. The coupling is encapsulated in PPO, a high-temperature resistant material, ensuring durability in demanding environments.

This component is designed for applications requiring precise control, including volume adjustment, motor speed regulation, and acoustic protection. It supports light adjustment and communication transmission, with typical use cases in automation and control systems. The LCR-0203 model features a cylindrical diameter of 6.0 mm and a length of 13.5 mm, with output lead length of 27.5 mm and input lead length of 25.0 mm. Lead diameter is 0.45 mm with a gap of 2.8 mm, and the input polarity is marked by an LED anode lead. PVC is used as the optional external material for additional protection.

Industries such as electronics manufacturing, automation, and telecommunications rely on this coupling for stable, isolated signal transmission. The product holds a manufacturing patent (ZL02225334.3), underscoring its technical originality. Buyers typically source this in bulk, with a minimum order of 1000 pieces, packaged in small boxes of 100 units. Delivery is confirmed within 3 working days from China. Payment terms include TT and Western Union, with the supplier based in Shenzhen, Guangdong.

Nanyang Senba Optical & Electronic Co., Ltd. is based in Building No.4, Huawan Industrial Zone, Gushu, Xixiang Street, Bao'an District, Shenzhen, Guangdong, China. The company specializes in the development and production of photoelectric components, including analog linear couplings, with a focus on precision and reliability. Its product line is backed by patents, such as ZL02225334.3 for this coupling, demonstrating a commitment to innovation in optical and electronic solutions.

The supplier operates with an imported tier classification and holds a harbor trust tier, indicating a baseline level of verification for international trade. While the listed response rate and average response hours are currently at zero, the company’s physical address and patented products suggest a tangible presence in the Shenzhen electronics manufacturing hub. Buyers are advised to confirm response times and technical support capabilities directly with the supplier before placing orders.
