KWD-CZS-A six-wire sensor , electronic weighing switch for elevator , elevator sensor , elevator weighing sensor
Decription:
This product is suitable for all movable car-bottom elevators that require overload signals and escalators that run in an energy-saving manner. It has a very high cost performance. Since the Hall sensor is used to achieve non-contact (induction) working mode, it does not directly bear the effect of elevator load, so it has a long working life and good stability. Overcome the defect that the mechanical overload switch is easily damaged.
In addition, this product has the characteristics of simple structure, small size, high precision, convenient installation and debugging, and low price, so as to realize the detection of elevator car overload.
Working principle:
This system is based on the principle of the elastic change of the movable car bottom when the elevator is loaded. The Hall sensor detects the displacement change, so as to realize the overload detection of the elevator car.
Red and black: power supply, AC/DC24V(±10%) 100mA, do not distinguish between positive and negative poles during DC output
Yellow and brown wires: relay moving and closing contacts
White and green wires: relay break contacts
Contact capacity: DC/AC48V/500mA
Note: Do not directly connect the output line of this product to an external power supply, so as not to cause a short circuit and damage the product
