Product description
The inductive linear position sensors of the Li-Q25L product series consist of a sensor and a po-
sitioning element. The two components form a measuring system for measuring for converting
the measured variable, 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
increments. The maximum measuring range of the sensor is determined by its length. How-
ever, the start point of the measuring range can be individually adapted using a teach-in
process.
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). The sensor and posi-
tioning element fulfill the requirements of protection class IP67 and can withstand vibrations of
moving machine parts as well as a range of other aggressive ambient conditions for long peri-
ods of time. The sensor and positioning element together enable contactless and wear-free
measuring. The sensors operate in absolute mode. Power outages do not require renewed zero
offset adjustment or recalibration. All position values are determined as absolute values.
Homing movements after a voltage drop are unnecessary.
