This special version provides a 0-10V sourcing analog output proportional to the sensing distance. This device is enclosed by a plastic face and a nickel-plated brass housing which meets NEMA 1, 2, 3, 4, 12, 13 and IP67 (IEC 529) enclosure standards. The electronic circuitry is potted for protection against shock, vibration and contamination. This sensor is available in 12, 18 and 30mm diameters with a 2m (6.5ft.) PVC cable connection.
