MX50 – Powerful SafeBond® MAX unit for larger cable connections
The MX50 is a battery-powered SafeBond® MAX unit developed for fast, reliable connections of larger cable dimensions – with zero metallurgical impact on the base material. With an automated process and silver-based technology, you achieve consistently low contact resistance and high quality in every connection.
- Zero impact – No metallurgical impact (no HAZ) on rail or base material
- Efficiency – 15–40 SafeBond connections per charge depending on cable size
- Automation – Patented self-adjusting gun for a fault-free process
- Flexibility – Handles up to 150 mm² with T-connection
- Mobility – Battery-powered Li-Ion technology, only 9.8 kg
The MX50 is designed to meet the demands of railway, grounding and cathodic protection applications where larger cable cross-sections require high performance without compromising safety or lifespan.
The SafeBond® MAX technology is based on an indirect arc brazing process using a silver-based material at approximately 650°C, resulting in an extremely strong and conductive bond without affecting the structure of the base material. The result is a long-term, corrosion-resistant connection with very low contact resistance.
The fully automated process simplifies installation: the operator activates the equipment and the system ensures the correct energy level and a perfect result every time. This minimizes handling errors and ensures repeatable quality in the field.
