Intrinsically Safe laser module


The SLM-635S is a laser module head which is Intrinsically safe. The laser head attaches to the 2 x AA, 2 x AA or 3 x C-cell removable battery modules which may be replaced in explosive atmosphere. This product is Certified under IECEx SIM 13.0005.

The module is identical in it's laser features to the SLX-635S laser which has an integrated battery module. It is rugged, simple to use, and provides a coaxially aligned beam for alignment applications in hazardous environments.

The benefits of the SLM-635S are that it may be clamped in place for permanent alignment, and the batteries replaced without disturbing the initial alignment. The module has a proprietary modulation feature that enables it to function with simple rotational laser detectors (in non-hazardous environments), or with the ART sensor modules. The sensor heads may be used for establishing laser barriers for detection of intrusion or entry to hazard zones, and also have features that enable them to be utilized in counting and speed functions for monitoring productivity and safety parameters.
