FR19 Fiber Optic Rotary Joint

Product Introduction

The FR19 fiber optic rotary joint is currently one of the smallest multi-channel fiber optic rotary joints, with a main body diameter of only 19mm, capable of accommodating up to 7 channels. It offers the option of single-mode, multi-mode, or a combination of both, and products with environmental resistance (shock, vibration, high and low temperatures) are also available.
