The Ethernet/IP-enabled LE-200 from TR Electronic, Troy, MI, is a laser distance measurement sensor. The emitter/receiver is positioned opposite a target and, as the distance between the two is varied, the position is evaluated and a corresponding value is transmitted from the device to the control system. Either the laser device, or its reflector, is fixed and the other end will move relative to it. The sensor is also available with Profibus and CAN interfaces. Applications include loop control, coil diameter measurement, automated warehousing, level and material control in silos, crane positioning, and general material handling of parts or containers over large scanning distances.
