快门选择反射光电开关时，两侧门柱安装感应范围为0-5米（适用于超过5米范围），高度为30-40厘米。当门扇运行自动下降时，有人或物体阻挡传感器，门感觉立即停止下降，自动上升到顶部。当物体被移动时，门体会自动降低到底部。它在自动手动时是有效的。

When selecting the reflective photoelectric switch for the shutter, the sensing range of the two door pillars installed on both sides is 0-5 meters (applicable to a range exceeding 5 meters), and the height is 30-40 centimeters. When the door leaf automatically descends and someone or an object obstructs the sensor, the door immediately stops descending and automatically rises to the top. When an object is moved, the door will automatically lower to the bottom. It is effective in automatic and manual mode.

快门的安全光幕设备适用于使用频率较高的公司，因为该装置的接触面会比安全光电大得多。门套两侧的光幕照射感应光源，只要触发到明显一个，快门就会立即停止运行，立即上升，安全性相对较高。

The safety light curtain device of the shutter is suitable for companies with higher usage frequency, as the contact surface of the device will be much larger than the safety photoelectric. The light curtains on both sides of the door frame illuminate the induction light source.
