JY-1370 Limit Switch Non contact limit switches belong to proximity sensors and are classified into inductive, magnetic, optical, ultrasonic, and capacitive based on measurement principles. Limit switch lift is a position sensor made using advanced technology and electromagnetic working principles. It can convert non electrical or electromagnetic quantities into desired electrical signals by measuring the positional relationship between sensors and objects, thereby achieving the purpose of control or measurement. Proximity switch is a type of switch type sensor (i.e. contactless switch) that has the characteristics of travel switch and micro switch. It also has sensing performance, reliable operation, stable performance, fast frequency response, long application life, strong anti-interference ability, and waterproof, shockproof, and corrosion-resistant characteristics Limit switch is a commonly used small current main control device. In electrical control systems, the function of position switches is to achieve sequential control, positioning control, and detection of position status.
In short, the elevator limit switch achieves elevator position control through mechanical triggering and electrical switches
Monitor and transmit status information to the elevator control system to ensure safety and smoothness during elevator operation.
