The Demag DGS-G4-142 is a maintenance-free, enclosed geared limit switch (part of the DGS-4 series, part number 87520133) designed for precise end-position shutoff of hoist motors. It offers infinitely variable switching point adjustment via screwdriver with a cut-out accuracy of ≤ ±2° maintained over the entire switch lifetime. The built-in counting mechanism records operating hours for maintenance scheduling, and provision for an electronic pulse generator allows additional monitoring. The "G" variant includes phase protection. Weighing 1.14 kg and manufactured in Germany, it is used in DH hoist units, roller doors, lifting platforms, rail-mounted travel units, distribution carriages, and telescoping mechanisms in crane and material handling applications.
**Q: What does the "G" in DGS-G4 mean?**
A: The "G" stands for closed design (enclosed housing), which provides better protection in industrial environments compared to the open DGS variant.
**Q: Is the DGS-G4-142 compatible with all Demag hoists?**
A: It is primarily designed for DH hoist units and can be retrofitted to many existing Demag hoist installations. Verify mounting compatibility with your specific hoist model.
