Pressure sensitive mat switch (Azbil Trading)

With excellent reliability and durability, this mat ensures a safe work area.

With the widespread use of FA, many industrial robots and NC machine tools have been installed in factories, creating an increasing number of dangerous areas for human beings. As a result, safety measures are needed for workers who enter dangerous areas, such as a means of stopping an industrial robot immediately and disabling its start switch. The pressure sensitive mat has excellent reliability and durability. Also, to provide industrial safety even if a wire should break, a circuit that detects a broken wire is available as a standard feature.

Characteristics

The pressure sensitive mat's internal contact has a sandwich structure consisting of a special urethane foam that has well-proven durability and flat ribbon wires. The outer surface is high-quality oil-resistant rubber. It is designed for indoor use.

  • Maintenance man-hours required for long product life are greatly reduced
  • Choice of two surface treatments: ribbed rubber or block rubber pattern to prevent slipping
  • Flexible rubber offers easy installation or repositioning.
  • High-quality oil-resistant rubber (NBR, in case of oil-resistant type)
  • Wire break detection feature can be installed as a safety enhancement
  • Non-directional and wide sensing zone
  • Various shapes are available to fit the facility layout
