Pictures for Sigma Elevator Magnetic Leveling Sensor Photoelectric Switch MPS-1600-OTIS

The sensor mainly gives the hoistway signal, the acquisition is collected by the main board, and the position is identified by the encoder. The signal given by the main board is used to determine how much voltage the inverter outputs and how fast the host responds to control the position of the car! During digital control, the leveling accuracy of the elevator can be adjusted by adjusting the crawling speed of the inverter!
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.
