zui多可有8对对射型安全光电传感器可连接到一个安全开关放大器上。SLA对射型光电传感器与SLVA放大器共同构成了一个保护模块系统，感应范围可达65 m。还有附加的Muting传感器和急停开关等安全设备可供使用者选择。不同型号的对射型安全光电传感器可以与放大器搭配使用，只要保证每对传感器的发射器和接收器是同一型号即可。

放大器包括了安全光电传感器的供电电源。对射型安全光电传感器的发射控制和接收器的信号分析（如光束被阻断）同样被放大器所代替。反射镜可以实现多边的保护。

p+f传感器应用：

基本应用于不断增加的危险区域。比如货盘系统，机器人，木工机械，包装机械，自动仓库和其它机器设备的入口保护。

倍加福SLA系列的对射型安全光电传感器是满足EN 954-1和EN 61496的等级2或等级4的，有自监控功能的光电安全设备。它必须与SLVA或SC4-8安全放大器配合使用。
