Avoiding influences from sporadic extraneous light from surrounding machines and preventing malfunction due to extraneous light such as light from other sensors passing close, spatter, AGV and patrol lights.
There is a possibility that a sensor cannot detect objects entering if a receiver receives other light for a long time around at the time it confirms incident light. Because of this, light curtain used to regard it as extraneous light and turn off output when light enters into light curtain at the closest time of incident light. However, it turns off against any kind of extraneous light regardless of dangerous light (that affects detection of object invasion) or non-dangerous light. This causes frequent machine stops due to extraneous light.

Scanning timing special processing
Retry processing
Less machine stops
Reduces malfunctions due to extraneous light with retry processing and scanning timing special processing.
This light curtain can avoid mutual interference by staggering the time of receiving light automatically in case that it receives light from light curtain next to it (extraneous light whose waveform and cycles are similar.)
This light curtain can avoid mutual interference by staggering the time of receiving light automatically in case that it receives light from light curtain next to it (extraneous light whose waveform and cycles are similar.)
It controls malfunction due to extraneous light to a minimum by not turning off output right away even when detecting sporadic extraneous light such as sensors equipped with AGV for preventing crushes and patrol lights and checking if it is dangerous or not within response time repeatedly (retry processing).

2. New method! Extraneous light prevention function
• The emitting method of light curtain
The emitter emits light from the beam channel 1, and the receiver 1 confirms incident light. Then, the beam channel 2 emits light. Thus, this is a method that they turn on the light in turns. • With conventional extraneous light check... If other light enters for a long time at the same time of the receiver receiving light, it regards the other light as abnormal extraneous light. Then, it turns off.
However, it turns off by any kind of incident light. It causes frequent machine stops.

Sensor A
If the sensor A and B emit light around at the same time, and light of the sensor A enters into the sensor B, it causes mutual interference.
The time of the sensor A’s emitting light and the sensor B’s receiving light can be staggered, which can avoid mutual interference.
* This is possible only with software without synchronization of the sensor A and B!
* Conventional sensors turn off here.

4. Reduction in total cost with series connections
Series connections are possible to a maximum of three sensors (192 beam channels), which reduces man-hours for wiring. In addition, we achieved a great reduction in cost because only one unit of safety relay unit is needed for a couple of sensors.

Simplified calculation of Simplified calculation of safety distancesafety distance
We achieved a high speed response time of 11ms regardless of numbers of beam channels. It simplifies calculation of safety distance. In addition, miniaturization of equipment is possible because it can shorten the distance between a dangerous part and light curtain by high speed response time.
