Slot-type photoelectric sensors are designed to detect the presence of slots. These precision instruments have many functions including counting, detection of parts and position control, in a variety of industrial and commercial situations. Technological features of this sensor are as follows. It emits a focused beam of light that is interrupted by the passing of an object, triggering an output signal. Intelligent circuitry has been incorporated to ensure trouble-free operation under virtually all environmental conditions. Uses are widespread for the slot type photoelectric sensor. They can be found in anything from production lines or assembly facilities, where they ensure which components have been assembled in what order, right on up through to logistics support points and automation systems which keep up-to-the-minute control of processes.razorback
