In the metalworking processes of production lines for automobiles and automotive parts, photoelectric switches come into contact with various oil-based coolants, breakdowns frequently occur mainly resulting from coolant penetrating the switch interior through cracks and cables, or other means. The Model H2B has been designed to reduce interruptions to production lines caused by switch breakdown, as well as increase factory operating efficiency.

The Model H2B features die-cast housing for shock resistance and a glass lens cover. By improving the sealing of cables and outlets, and filling cable interiors with epoxy resin, Azbil has enhanced the switches’ protection from coolants.


1 Robust construction and superior oil resistance

  • Die-cast housing and glass lens cover construction does not use resin, which prevents cracking.
  • Multiple sealing prevents coolant from seeping into gaps and other small openings.
  • Cable interior filled with epoxy resin to prevent coolant from seeping in.

2 Inclusion of a model that includes a slit

  • Increased detection performance of small objects due to a narrowed light beam, which is useful when detecting tools with a small diameter or differentiating irregularly-shaped parts.

3 Inclusion of a standard model with a 10-meter cable

  • Eliminating the need for an extension cable prevents coolant from seeping in where the cables connect.
