Spot size and focal distance are adjustable, so there is no need to change the distance between the sensor and the target. This narrow beam helps avoid deflection and is suitable for detecting objects at. Photoelectric sensors come with a variety of light emission types (infrared, visible red, laser Class 1 and 2), sensing technologies (diffuse, background suppression, reflective, through-beam), and housing configurations (photo eye or fiber optic). A longer fiber unit can be installed at a location farther from the fiberoptic amplifier. To use a fiber unit at high ambient. How to Transforms a Collimated Laser Beam with Elliptical Cross-section into a Circular Beam or Vice Versa. Figure 1: Key. Because the fibre does not house any of the electronic components, there are very few limitations on size and shape. The following is a classification example of KEYENCE's fibre units (FU Series). Other considerations include cable material, emitted beam, modes of operation, body type and various features.
