Brief Product Description

EMG LID43.03 is a high-precision inductive linear displacement transmitter from EMG Automation GmbH, specially designed for web edge guiding and position feedback control systems. It adopts non-contact inductive measurement principle, converts plunger mechanical stroke into standard 4-20mA analog signal, provides real-time position feedback for EMG edge guiding controllers and hydraulic actuators. Aluminum alloy housing with IP65 protection grade, suitable for rolling mill, steel strip, paper and film harsh industrial environment. This legacy sensor has been phased out, only tested surplus and refurbished units available for existing guiding system maintenance and spare replacement.

Core Product Functions

• Non-contact inductive linear displacement sensor for EMG web guiding system
• Power supply: 24VDC (18~30VDC allowable range)
• Standard output: 4~20mA analog current signal
• Linear error: less than 0.5% full scale, high repeatability

• Hydraulic actuator displacement monitoring in heavy industry equipment
• Legacy EMG edge guiding system spare replacement and maintenance

FAQ (Frequently Asked Questions)

• Q: Abnormal 4-20mA output or no position feedback after installing LID43.03?
  A: Check 24VDC supply, M12 connector shielding and wiring, plunger mechanical jamming, sensor linearity drift, and cable damage.
• Q: What is difference between LID43.03 and ID43.03?
  A: LID43.03 is linear displacement sensor for hydraulic cylinder position feedback; ID43.03 is edge position inductive sensor detecting steel strip edge directly.
• Q: Can LID43.03 work with other brand deviation correction controllers?
  A: The 4-20mA signal can theoretically be read by general PLC/controller, but it is originally matched with EMG EVK series guiding controller for best performance.
• Q: Is EMG LID43.03 available for new projects?
  A: End-of-life product, no new original production. Recommend latest EMG displacement sensor series. Only surplus/refurbished tested spares for existing web guiding systems.
• Q: Common failure points?
  A: Internal coil aging, waterproof seal failure, M12 connector pin corrosion, plunger stuck by dust or metal debris.
