LZ-25 Series
LVIT Linear Position Sensor
Through-bore LVIT Linear Position Sensor with Superior Stroke-to-Length Ratio

The LZ-25 Series of LVIT (Linear Variable Inductance Transducer) position sensors are contactless devices designed for frictionless measurement 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.

This sensor is offered in nominal full scale ranges from 2 to 36 inches (50 to 900 mm) with an excellent stroke-to-length ratio, so that the sensor's overall length is only 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 radial 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.

For more information see the technical datasheet below.
