LZ-25: The Next Revolution in LVIT Technology


H. G. Schaevitz LLC, Alliance Sensors Group has expanded its sensor product offering using LVIT Technology by adding the LZ-25 Series linear position sensors. These are contactless devices designed for use in factory automation or assembly machinery applications where space is a premium, as well as for external mounting on hydraulic cylinders to sense rod position. These LVITs are offered in nominal full scale ranges from 50 to 900 mm (2 to 36 inches) with an excellent stroke-to-length ratio so that the sensor’s overall length is only about 38 mm (1.5 inches) longer than the linear range of the unit. The sensor has a 25.4 mm (1 inch) outside diameter aluminum or optional stainless steel body with a 1-m long radial exit cable for I/O connections. The 7.5 mm (0.295 inch) diameter through-bore of an LZ-25 provides clearance for its 6.35 mm (0.25 inch) diameter moving rod, which is made of the same material as its housing. This through-bore feature also means that the sensor is not subject to damage from typical mechanical overstroking.
