SLX-635S : Sensor enabled laser

The SLX-635S laser is identical in features and appearance to the well-known SLX-635P laser, with the only differing characteristic being that it has a proprietary modulation on the laser beam to enable sensors to lock into the laser itself. The SLX-635S is another of our small Intrinsically Safe lasers. It is rugged, simple to use, and provides a coaxially aligned beam for alignment applications in hazardous environments. This product is IECEx Certified .

Manufactured in Australia for the past 15 years the 'Pencil Laser' as it is often referred to in the Coal Mining Industry, has been constructed with solid Zn plated Brass enabling permanent safety information labeling. These lasers have been the standard alignment tool used in underground coal mines in Australia since their initial approvals.
