Keep the optical window of CRT 648-32.G/L44-M12 clean — even a thin dust film can reduce the operating range or trigger false outputs. / 保持 CRT 648-32.G/L44-M12 光学窗口清洁,薄薄一层灰尘也会降低有效检测距离或导致误触发。
Confirm the supply voltage (typically 10–30 V DC) and PNP/NPN logic match the PLC input card before wiring. / 接线前确认供电电压(通常 10–30 V DC)与 PNP/NPN 输出逻辑,与 PLC 输入卡匹配。
When replacing with an equivalent, double-check the connector pinout (M8 / M12) and mounting hole pattern. / 使用等效替代件时,务必核对连接器引脚定义(M8 / M12)与安装孔位。
