Welcome to our store! 1. MAIN PURPOSE: The fiber optic sensor uses light sensing to convert the state of the measured object into a measurable optical signal. 2. SPECIFICATIONS: The outer diameter of the optical fiber is 1.2mm, and the inner diameter is 0.5mm. The wire is soft, lightweight, and durable. 3. ADVANTAGES: This sensor offers good insulation, non-inductive electrical performance, and resistance to high temperatures and corrosion. 4. DIFFUSE REFLECTION: Uses a diffuse reflective digital fiber optic probe to ensure higher detection performance, good reliability, and stability. 5. 1 METER CABLE: The fiber optic sensor has a wire length of 1 meter, which is convenient for connecting circuits and less limited by space. Item Type: Fiber Optic Sensor Model: FRS 310 S Sensing Method: Light Sensing Fiber Optic Outer Diameter: 1.2 mm Fiber Optic Inner Diameter: 0.5 mm Cable Length: Approx. 1 meter / 3.3ft 1 x Sensor 2 x Nuts 2 x Accessories Customers are our top priority.
