IFM Electronic E20161 Fiber Optic Through-Beam Sensor is a fiber optic through-beam sensing device designed for non-contact object detection across a defined gap in industrial environments. The E20161 model identifies this specific IFM part within its fiber optic through-beam family. In a typical through-beam configuration, an optical emitter and receiver establish a beam path; when the beam is interrupted by a target, the sensor signals presence or absence. This setup is commonly used on automation lines, conveyors, and material handling tasks where contact-free sensing is advantageous.
