Photoelectric Sensors for Harsh Environments Model H2B

Azbil Photoelectric Switches for Harsh Environments Model H2B are designed for long term use in harsh environments such as those in the metalworking processes of automotive manufacturing equipment.

For automating manufacturing equipment such as machine tools, the metalworking processes of production lines for automobiles and automotive parts require many photoelectric switches. Most switches currently employ resin housing due to their intended use in clean environments. However, breakdowns frequently result when used in metalworking processes that encounter various oil-based coolants due to coolant penetrating the switch interior through cracks, cables, or other pathways.

Azbil offers an environment-resistant model that has dramatically improved robustness and oil resistance over standard models and contributes to the stable and reliable operation of production lines in harsh environments. The Model H2B features die-cast housing for shock resistance and a glass lens cover. Azbil has enhanced the switches’ protection from coolants by improving the sealing of cables and outlets and filling cable interiors with epoxy resin. Model H2B is designed to reduce interruptions to production lines caused by switch breakdown and increase factory operating efficiency.
