Description
The EMG LID43.03 is a high-precision inductive sensor used for linear displacement measurement in strip guiding systems. It converts the mechanical position of a plunger into a standardized electrical signal, providing the reliable feedback necessary for accurate center-line or edge control in metal processing and rolling mills.

Application Areas
- Metal strip guiding systems (SMI, SPC)
- Steel and aluminum rolling mill positioning
- Coil winding and unwinding tension control
- Hydraulic cylinder position feedback
- Heavy-duty industrial linear motion monitoring
Product Q&A
- Q: Is the LID43.03 compatible with older EMG electronics?
- A: Yes, it is designed to interface with EMG’s standard evaluation units like the MCU or SPC series.
- Q: Does the sensor require regular calibration?
- A: Due to its inductive non-contact design, it is virtually wear-free, though periodic zero-point checks are recommended during maintenance.
- Q: Can it operate in oily or humid environments?
- A: The IP65 rating and sealed construction make it suitable for environments with oil mist and moisture common in metal processing.
