If you know the operation principle of the detection light curtain, you should know that the detection light curtain is induced by emitting infrared rays through the transmitter and receiving infrared rays through the receiver. When our hands or other parts pass through infrared rays, the detection light curtain can give signals to make corresponding detection and measurement calculations. Since one emits infrared rays and the other receives infrared rays, Our detection light curtain needs to be aligned when it is installed. In addition, our aiming distance is generally required. We know that the light of the flashlight is straight at the beginning, but it is scattered later. The same is true for the detection light curtain. If the distance is too far, it will be scattered. Therefore, we generally need to tell our manufacturer the aiming distance we require before purchasing the detection light curtain. Others shall be determined with our measurement grating manufacturer.

At this time, our consumers have to ask whether our detection light curtain must be very accurate. There is a certain deviation between the detection light curtain illuminator and the light receiver, as long as they are roughly aligned. For example, the detection light curtain of our xaroi has an indicator light. When we install the detection light curtain, we look at the light receiver or controller. After the light is turned on (that is, you say it is aimed), the indicator light turns green. In the light blocking state (that is, it is not aimed or something blocks the infrared ray), the indicator light shows a red light. In this way, we can ensure that our detection light curtain is aimed.
