Fiber optic linear position and displacement sensor fod description The fod is a fiber optic linear position and displacement sensor that provides high accuracy, absolute measurements of position and displacement. The fod is well suited for difficult to reach locations and hazardous environments such as those containing explosive materials. Fiber optic linear position and displacement sensor fod specifications 1) linear stroke : 20 mm (0.8 in) 2) resolution: 0.002 mm (0.00008 in) 3) accuracy: â±0.02 mm (0.0008 in) 4) connector type: st connector 5) operating temperature : -20'c to 170'c ( -4'f to 338'f) Fiber optic linear position and displacement sensor fod features: Intrinsically safe Immune to emi/rfi Up to 170'c (338'f) Resolution of up to 0.002 mm 20 mm linear stroke Aluminum or composite material housing Fiber optic linear position and displacement sensor fod applications: Microwave and rf environments In-situ process monitoring Harsh and hazardous environments High-temperature environments
