Product Description
The inductive linear position sensors of the Li-Q25L series with an analog output consist of a
sensor and a positioning element. The two components form a measuring system for measur-
ing and converting the measured variable for Length and 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 steps, in the 1000...2000 mm range, variants are avail-
able in 250 mm steps. The maximum measuring range of the sensor is defined by its length.
However, the measuring range can be individually adapted with a teach operation.
The sensor is housed in a rectangular aluminum profile.
The positioning element is available in different designs 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
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 recalibra-
tion. All position values are determined as absolute values. Homing movements after a voltage
failure are unnecessary.
