SLX-635S Intrinsically Safe Laser
The SLX-635S is an intrinsically safe red laser system engineered for hazardous environments including mining, oil & gas, agriculture, and industrial applications. Based on the proven SLX-635P, used in underground mining for over 20 years, this model is rugged, reliable, and designed for demanding conditions.
With a visible 635nm red beam, long battery life, and enhanced optics, the SLX-635S ensures superior beam definition over distance. Its modulation capability makes it automation-ready, supporting sensing and guidance technologies. Compact, robust, and intrinsically safe, it is trusted for safety and performance in critical industries.

📦 Package Options:
🔹 SLX-635S 3AA (Class 2)
-Laser Power: < 1.0 mW
-Laser Class: Class 2 (IEC 60825-1)
-Beam Safety: Considered “eye-safe” for momentary exposure (like a standard laser pointer).
-Use Case: Ideal for general alignment in hazardous zones where safety is top priority.
🔹 SLX-635S 3AA3R (Class 3R)
-Laser Power: up to 5.0 mW
-Laser Class: Class 3R (IEC 60825-1)
-Beam Safety: Brighter and longer range, but requires stricter precautions — not considered eye-safe for direct exposure.
-Use Case: Preferred where longer distance visibility and stronger beam definition are needed (e.g., tunneling, large-scale underground operations).
