The optical axis diameter is the beam size that the Through-beam Fiber Unit uses for detection. If you are detecting objects larger than the optical axis diameter, you can expect stable detection performance because the object will block all of the beams of light that are used for detection. The incident level may fluctuate, however, if the workpiece passes the beam at high speed. In this case, it is best to select a Fiber Unit with a smaller optical axis diameter, or change the response time of the Fiber Amplifier Unit to High-speed mode or to Super-high-speed mode setting.
Beam spread of 60° Optical axis diameter Are there any differences between the Fiber Units that are used for emitter and receiver? With Through-beam Fiber Units, there is no difference between emitter fibers and receiver fibers. With Reflective Fiber Units, the emitter fibers and receiver fibers are different on Coaxial Reflective Models. Emitter fiber cables have identification marks. Refer to the individual dimensions diagrams of Fiber Units for details. What size must the hole be to mount a Threaded or Cylindrical Fiber Unit? Refer to the recommended mounting hole dimensions given on pages 58 to 61. Are Fiber Cables available in different lengths?
Some models are available with either 5-m or 10-m cable. Ask your OMRON representative for details. What is the aperture angle? The aperture angle is the angle at which the emitter beam spreads out. Aperture angle Are these Fiber Units CE certified? Fiber Units do not have any electrical components and therefore are exempt from CE certification. Can these Fiber Units be used in explosionproof areas? Explosion-proof certification has not been obtained. Depending on the country in which the Fiber Units are used and how they are used, certification may be required. Check the relevant laws and regulations before use. What the Fiber Units with built-in lenses?
These highly recommended Fiber Units have built-in lenses that achieve stable detection with high-power beams. Fiber Amplifier Units Can the Fiber Amplifier Unit be operated from a mobile console? Mobile consoles cannot be used with either the E3NX-FA Series or the E3X-ZV Series. Can a Sensor Communications Unit be used? If you use E3NX-FA0 Amplifier Units, you can use the E3NW-ECT(EtherCAT), E3NW-CRT(CompoNet) or E3NW-CCL (CC-Link).
