原理及特点发光器发出的光直射到受光器，形成保护光幕。当光幕被遮挡时，受光器产生一遮光信号，通过信号电缆传输到控制器，控制器将此信号进行处理，产生一控制信号，控制机床的制动控制回路或其他设备的报警装置，实现机床停车或安全报警。保护高度因规格而不同，从100mm到1240mm均为常规产品。光轴间距分为20mm，30mm，40mm三种，分辨力分别为30mm，40mm，50mm。采用对射式设计，小巧美观，安装方便。规格型号光束数光距间距20mm保护高度光距间距30mm保护高度光距间距40mm保护高度6KS02A/B0620100mmKS02A/B0630150mmKS02A/B0640200mm8KS02A/B0820140mmKS02A/B0820210mmKS02A/B0840280mm10KS02A/B1020180mmKS02A/B1030270mmKS02A/B1040360mm12KS02A/B1220220mmKS02A/B1230330mmKS02A/B1240440mm14KS02A/B1420260mmKS02A/B1430390mmKS02A/B1440520mm16KS02A/B1620300mmKS02A/B1630450mmKS02A/B1640600mm18KS02A/B1820340mmKS02A/B1830510mmKS02A/B1840680mm20KS02A/B2020380mmKS02A/B2030570mmKS02A/B2040760mm22KS02A/B2220420mmKS02A/B2230630mmKS02A/B2240840mm24KS02A/B2420460mmKS02A/B2430690mmKS02A/B2440920mm26KS02A/B2620500mmKS02A/B2630750mmKS02A/B26401000mm28KS02A/B2820540mmKS02A/B2830810mmKS02A/B28401080mm30KS02A/B3020580mmKS02A/B3030870mmKS02A/B30401160mm32KS02A/B3220620mmKS02A/B3230930mmKS02A/B32401240mm
