4. Product Introduction
The EMG LS43.0124 is a compact sensor module that detects and quantifies electrical signals generated by muscle activity. It delivers a 0-100 mV measurement range with ±1.5% accuracy and high input impedance for clean signal capture in laboratory and field setups.
Engineers select this unit for its small footprint, stable output impedance under 10 Ω, and straightforward integration into data-acquisition systems used in biomechanics testing, physical-therapy instrumentation, and sports-science measurement rigs. Verify exact signal conditioning and electrode compatibility against the application requirements before final installation.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No output signal | Electrode contact failure or open cable | ❌ Low | Measure continuity from sensor leads to electrodes with multimeter | Inspect and reseat electrode connections first |
| Unstable or noisy reading | High ambient electrical noise or poor grounding | ✅ Medium | Check ground continuity and shield integrity; observe signal with known muscle contraction | Improve shielding and verify clean ground path |
| Output saturates or clips | Input exceeds 100 mV or incorrect gain setting downstream | ✅ High | Apply known low-level test signal within 0-100 mV and monitor output | Confirm measurement range and any external amplification |
| Zero offset drifts | Temperature outside −10 °C to +50 °C or aging electronics | ✅ Medium | Record ambient temperature and compare against rated range | Bring unit into specified temperature band and retest |
| Intermittent signal drop | Loose connector or mechanical stress on leads | ❌ Low | Wiggle cables while monitoring output | Secure connectors and relieve cable strain |
If symptoms persist after these checks, capture photos of the installation, electrode placement, and any diagnostic waveforms, then contact technical support with the data.
6. Frequently Asked Questions (FAQ)
Q: Is the LS43.0124 a new original unit or refurbished?
A: This listing is New Original (New Surplus). It has not been previously installed or powered in the field. We perform visual inspection, basic functional verification of the measurement path, and package it in ESD-safe materials before shipment.
Q: What is the exact measurement range and accuracy?
A: The sensor covers 0-100 mV with ±1.5% accuracy. Input impedance exceeds 10 MΩ and output impedance stays under 10 Ω. Confirm these values against your signal-conditioning chain before integration.
Q: Can I use this sensor outside the −10 °C to +50 °C range?
A: No. Operation outside that window can shift offset, increase noise, or damage internal components. Keep the unit within the rated temperature band during both storage and use.
Q: Does the module include electrodes, cables, or calibration software?
A: The base unit ships as the sensor module only. Electrodes, interconnect cables, calibration data, and software are not included unless explicitly listed in the order. Order matching accessories separately if required.
Q: How do I verify the unit is working before field installation?
A: Apply a known low-level differential test signal within 0-100 mV across the input while monitoring the output with a scope or DAQ. Confirm the output tracks the input within the stated accuracy and that no excessive noise appears. Document the result for your records.
Q: What is the warranty and typical lead time?
A: Units ship with a 1-year warranty covering manufacturing defects under normal use. Stock items typically ship within 3-5 business days after payment confirmation.
