Contactless LVIT Position Sensors have through-bore design.

Press Release Summary:

Designed for use in factory automation or assembly machinery applications and external mounting on hydraulic cylinders to sense rod position, LZ-25 Series uses LVIT Technology™ and comes in nominal FS ranges from 2–36 in. Overall length is ~1.5 in. longer than linear range of unit, and 1 in. OD aluminum or stainless steel body has 1 m long radial exit cable. In addition to negating damage from mechanical overstroking, 0.295 in. dia through-bore provides clearance for 0.25 in. dia moving rod.

LZ-25 Series LVIT Inductive Linear Position Sensors

Through-bore Sensors for Applications Needing SUPERIOR Stroke-to-Body-Length

Moorestown, New Jersey – 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.


• LVIT Technology™ (Linear Variable Inductance Transducer)

• Contactless operation prevents internal wearout from dithering or rapid cycling

• Excellent stroke-to-body-length ratio

• Full Scale ranges from 50 to 900 mm (2 to 36 inches)

• Through-bore design eliminates mechanical overstroking damage

• DC in / DC out operation with built-in electronics

• Proprietary SenSet™ field adjustable range scaling
