Inductive Sensor 921LC2-Z703 Pepperl-Fuchs
Switching function: Normally closed (NC), Output type: NAMUR, Installation: flush, Output type: 2-wire, Construction type: Cylindrical, flat, Series: Cylindrical type, Type of voltage: DC, Connection type: 0.5 m, PVC cable, Housing material: PA, Degree of protection: IP67
Working Principle
Oscillator: The sensor contains a high-frequency oscillator that produces a magnetic field.
Magnetic Field: When a metal object enters the sensor's detection area, a change occurs in this magnetic field.
Eddy Currents: The metal object creates eddy currents on its surface. These currents cause a weakening in the sensor's oscillator.
Trigger: This weakening is detected as a change in the sensor circuit and an output signal is produced.
Advantages
Since it performs non-contact detection, there is no mechanical wear and tear problem.
It has a fast response time.
It can work in harsh environmental conditions (such as dust, oil, water).
It is reliable and has a long service life.
Areas of Use
Automation and production lines.
Robotic systems.
Conveyor belts.
CNC machines.
Safety systems (for example, to detect whether covers are closed).
