Excellent quality: reliability, good stability, wear resistance, corrosion resistance;
Good transparency: transparent plastic optical fiber inner core, stable signal transmission, low loss, and toughness that is not easy to break;
Durable and resistant: The head is made of stainless steel material with high strength, which is sturdy and resistant to corrosion and rust in humid environments.

Non coaxial fibers: 2 fiber cores, one of which is the transmitting fiber and the other is the receiving fiber.
Coaxial optical fiber: There is a transmitting optical fiber in the middle and a receiving optical fiber around it, making detection more accurate. The fiber cores that receive light are arranged around them, and even if the detection object is detected from different directions, the error is very small.
