Area Light Curtain Sensor Photoelectric Proximity Switch LG20 series LG20-T2405TNA-F2 20Axis
The area sensor is composed by optical emitter and receiver, all in a housing, with high quality aluminum alloy as the basic framework. The object will block a part of light emitted from the emitters to the receivers when it was to be placed between emitters and receivers. Area sensor can identify the area which is blocked by synchronous scanning. At first, a emitter send the light beam, and the corresponding receiver look for this pulse in the same time. It finishes a scan for a passage when the receiver get this pulse, and moves to the next passage untill it finished all scan.
