What is the function of elevator code reader?

Magnetoresistive sensor: According to the principle of electric field and magnetic field, when a current is applied in the length direction of the ferromagnetic alloy strip, if a magnetic field is applied in the direction perpendicular to the current, there will be an inhomogeneity of magnetoresistance in the ferromagnetic material. appears, thereby causing the resistance of the alloy strip itself to change. Magnetoresistive sensors are made based on this principle.

Elevator Sensor – FAQs

Q1: What types of sensors are commonly used in elevator systems?
Elevators use sensors for position detection, leveling, door monitoring, and other control functions. Common sensing technologies include magnetic, inductive, and photoelectric types, depending on the application.

Q2: Can elevator sensors with the same appearance be interchangeable?
Not necessarily. Similar-looking sensors may differ in sensing principles, supply voltages, output logic, detection distances, or connector arrangements.

Q3: What is the difference between NPN and PNP sensor outputs?
NPN and PNP sensors use different transistor output configurations. The correct type depends on the input circuit and wiring requirements of the elevator controller.

Q4: What can cause an elevator sensor to provide an incorrect signal?
Possible causes include incorrect alignment, damaged wiring, unstable power supply, contamination, electrical interference, or sensor failure. The connected controller and sensing target should also be checked.

Q5: What information is required to identify a replacement elevator sensor?
Please provide the original part number, sensing type, supply voltage, output signal, sensing distance, mounting dimensions, and connector details.
