DW-01 Hitachi Elevator Eddy Current Load Sensor

Description

The Hitachi DW-01 is a high-precision eddy current sensor engineered for non-contact load detection and car bottom weighing in elevator systems. Utilizing electromagnetic induction to measure distance variations between the sensor and the elevator car frame, it provides real-time feedback for overload protection and floor leveling accuracy. This industrial-grade component features a robust housing designed to withstand the high-vibration environment of elevator shafts while maintaining a stable output signal for the lift controller.
