  • Compact size (PS type)
  • Precision semiconductor pressure sensor that contributes to downsizing of the apparatus.
  • Pressure type
    ・Standard type(with glass base) : Rated pressure 4.9 kPa to 980.7 kPa
    ・Economy type(without glass base) : Rated pressure 40 kPa

RoHS compliant

Features

  1. Ultra-miniature size: much more compact than the PF pressure sensors offered in the past

    • Base area:7.2(W)×7.2(D) mm .283(W) × .283(D) inch
    • Only 60% in mounting area and 91% in overall height of previous models (PF)

    Ultra-miniature size: much more compact than the PF pressure sensors offered in the past

  2. High-level precision and linearity

    A high degree of precision and linear detector response have been achieved by applying the semiconductor strain gauge system. Highly reproducible based on repeated pressure.

  3. Impressive line-up of models

    • Taking their place alongside the standard 5kW bridge resistance models are those with a 3.3kW resistance which is optimally suited to 5V drive circuits.
    • Economy model (no glass base) gives outstanding value for customer appliances 40kPa(0.4kgf/cm2) and 49kPa(0.5kgf/cm2) units are also available.
  4. Improved ease of DIP pin insertion into printed circuit boards

    • The ends of the DIP pins are chamfered to ensure easy insertion into printed circuit boards.

    Example of pressure characteristics
    (when the rated pressure is between
    98.1 kPa{1.0kgf/cm2})

    Drive current: 1.5 mA rated current; ambient temperature: 25°C 77°F

    The ends of the DIP pins are chamfered to ensure easy insertion into printed circuit boards.
