Product Description
The inductive linear position sensors of the Li-Q25L series consist of a sensor and a positioning
element. The two components form a measuring system for measuring and converting the
measured variable for length or position.
The sensors are supplied with a measuring length of 100…2000 mm: In the 100…1000 mm
range, variants are available in 100 mm increments, in the 1000…2000 mm range in 250 mm in-
crements. The maximum measuring range of the sensor is determined by its length. However,
the start point of the measuring range can be individually adapted with a teach operation. The
gradient of the output characteristic also stays the same after the start point has been changed.
The sensor is housed in a rectangular aluminum profile. The positioning element is available in
different variants in a plastic housing (cf. Accessories list in chapter 4.5). Sensor and positioning
element comply with degree of protection IP67 and can withstand the vibrations of moving
machine parts as well as being resistant to a number of aggressive environmental media.
Sensor and positioning element together enable contactless and wear-free measuring. The
sensors operate in absolute mode. Voltage failures do not require renewed homing or recalib-
ration. All position values are determined as absolute values. Homing movements after a
voltage drop are unnecessary.
