photoelectric limit switch
It uses light to sense the presence or absence of an object: an advanced sensor called photoelectric limit switch. In industrial automation systems, it mainly includes positioning detection, counting and safety guarding. Technological features of this switch incorporate non-contact detection, which lowers failure rates; it works on any kind of material regardless color, reflective index or surface condition--which gives the switch great adaptability for use in different situations. It is most widely used in packaging, materials handling and robotics applications, offering reliable control under various conditions.
