Photoelectric Sensors for Harsh Environments Model H2B

Model H2B Photoelectric Switches for Harsh Environments

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

Automating machine tools and other equipment on automobile and automotive parts production lines requires many photoelectric switches. Most switches use resin housings because they are intended for clean environments, so breakdowns are frequent in metalworking processes, where oil-based coolants penetrate the switch interior through cracks, cables, or other pathways.

The Model H2B dramatically improves robustness and oil resistance over standard models. It features a die-cast housing for shock resistance and a glass lens cover, improved sealing of cables and outlets, and cable interiors filled with epoxy resin. The result is fewer production line interruptions caused by switch breakdowns and higher factory operating efficiency.

Features

Robust construction and superior oil resistance

  • The die-cast housing and glass lens cover do not use resin, which prevents cracking.
  • Multiple sealing mechanisms prevent coolant from infiltrating gaps and other small openings.
  • The cable interior is filled with epoxy resin, which acts as a barrier against coolant seeping in.

Models with a slit

  • A narrowed light beam improves detection of small objects, which is useful when detecting small-diameter tools or differentiating irregularly shaped parts.

Standard models with a 10 m cable

  • Eliminating the need for an extension cable ensures a tight, secure connection that effectively prevents coolant leaks.

Applications

Production area

Machine tools, machining areas

Photoelectric switches are constantly exposed to coolant when the metal parts being cut are covered in coolant during machining.

Production area

Machine tools, tool changing areas

Extremely close to the machining section, with coolant mist constantly in the air. Accurately detecting tools of varying sizes requires a photoelectric switch with a narrow beam.

Transport of metal parts

Extremely close to the machining section, with coolant mist constantly in the air. Differentiating various metal parts for transport requires a photoelectric switch with a narrow beam.
