SLX-635P IS laser

The SLX-635P is a small Intrinsically Safe laser. It is rugged, simple to use, and provides a coaxially aligned beam for alignment applications in hazardous environments. This product is IECEx Certified under IECEx SIM 13.0005, previously under IECEx SIM 09.0005. Products are fully supported under our new Certification IECEx SIM 13.0005.

Manufactured in Australia for the past 23 years for the Coal Mining Industry, the SLX-635P has been constructed with solid Ni 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.
