大多数玻璃纤维光缆具有圆形传感头，玻璃纤维以圆形配置排列。其他电缆，如43GT-FIS40SL，为玻璃纤维提供带有矩形开口的传感头，称为“开槽”电缆（见下图）。控制接口端头传感端头使用这些等效直径来确定开槽电缆的大致性能。槽尺寸[mm（in.）]圆形传感头等效直径[mm（英寸）]2.5 x 0.5（0.1 x 0.02）1.2（0.046）0.5 x 2.5（0.02 x 0.1）1.2（.046）5.1 x 0.25（2.0 x 0.01）1.2（0.04）9.7 x 0.8（0.382 x 0.032）3.1（0.125）公式：近似直径=1.128 x长度x宽度注意：不建议将光纤电缆用于危险环境中的防爆应用。光纤电缆可以为爆炸性烟雾提供从危险区域到安全区域的路径。玻璃光纤电缆简介PHOTOSwitcher光电传感器请访问我们的网站：www.ab.com/catalogs。1--235首选可用性类别。编号以粗体打印。用于大孔径传感器的玻璃光纤电缆第1-236…1-250页上的光纤电缆用于下面所示的大孔径传感器。42GxF---900x大孔径传感器：42SRF--60xx 42SRF--65xx 42GTGF-100x0 42GTGF-103x0 42xRx---5x00FO 42GxF---900x 42EF--G1xxA 42KL--G1xxx注：标称传感距离•由于光纤电缆之间的差异，传感距离可能变化很大•分叉电缆的传感距离用白纸测量（90%反射率）。其他表面可能反射性较低，因此传感距离较短。•公布的数字基于广泛的测试，并且是保守的•传输光束电缆的传感距离是从尖端到尖端测量的•影响距离的应用考虑因素•选择的传感器•目标的反射率•环境•附件，如增程透镜•电缆的长度•咨询产品支持以了解更多信息信息
Most glass fiber optic cables have round sensing tips with the glass fibers arranged in a circular configuration. Other cables such as 43GT--FIS40SL offer sensing tips with a rectangular shaped opening for the glass fibers, referred to as “slotted” cables (see illustration below). Control Interface End Tip Sensing End Tip Use these equivalent diameters to determine the approximate performance of slotted cables.

The fiber optic cable can provide a path for explosive fumes to travel from the hazardous area to the safe area.

Glass Fiber Optic Cables for use with Large Aperture Sensors The fiber optic cables on pages 1--236…1--250 are for use with the large aperture sensors shown below. 42GxF--900x Large Aperture Sensors: 42SRF--60xx 42SRF--65xx 42GTGF--100x0 42GTGF--103x0 42xRx--5x00FO 42GxF--900x 42EF--G1xxA 42KL--G1xxx Note: Nominal Sensing Distance • Due to the variation between fiber optic cables, sensing distance can vary widely • The sensing distance of bifurcated cables is measured with white paper (90% reflectivity). Other surfaces may be less reflective and therefore would have shorter sensing distances. • The published numbers are based on extensive testing and are conservative • The sensing distance of transmitted beam cables is measured from tip to tip • Application considerations that effect distance • Sensor selected • Reflectivity of target • Environment • Accessories such as range extending lenses • Length of the cable • Consult with product support for additional information.
