Capacitive proximity sensors from Carlo Gavazzi offer an adjustable sensing distance of 2-10 mm flush or 3-15 mm non-flush, and are available in 12 mm (about 0.47 inch), 18 mm (about 0.71 inch), and 30 mm (about 1.18 inch) diameters with AC and DC outputs. These patented Tripleshield sensors are tested to withstand electrostatic discharges up to 40 KV, line transients up to 4 KV, and airborne noise up to 15 V/m.
