3-1-1 ZX-L Series Outline
The ZX-L Series consists of high-accuracy, advanced sensors designed to
use a laser light emitted onto the sensing object to measure the distance
between the sensing object and the Sensor Head, judge the sensing
object surface status, position, and obtain width measurements. A Sensor
Head and Amplifier Unit are used in combination.
3-1-2 Sensor Heads
A Reflective Sensor Head measures the distance between the Sensor
Head and the sensing object using emitter and receiver elements. The
value is converted to an electric signal and sent to the Amplifier Unit.
With a Through-beam Sensor Head, the emitter radiates the laser beam
as a collimated light beam, and the receiver senses the variation in inci-
dent level caused by the sensing object. The value is converted to an elec-
tric signal and sent to the Amplifier Unit.
3-1-3 Amplifier Units
The signal from the Sensor Head is received and the value is displayed
and output externally. Holding and timing controls are performed. In addi-
tion, two Amplifier Units can be connected to each other to perform calcu-
lations.
3-1-4 Calculating Unit
A Calculating Unit is required to connect two Amplifier Units.
Calculations of A
−
B and A+B can be performed when two Units are con-
nected.
Various settings of Amplifier Unit reset to the default status when
the Sensor Head is replaced with one with a different sensing dis-
tance.
