FEATURES
• Improved ease of DIP pin insertion
into printed circuit boards
• Ultra-miniature size: much more
compact than the PF pressure sen-
sors offered in the past
Ultra-small
miniature
The ends of the DIP pins are chamfered to
ensure easy insertion into printed circuit

• High-level precision and linearity
Anode
junction
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.
• Impressive line-up of models
• Taking their place alongside the standard
5kΩ bridge resistance models are those
with a 3.3kΩ resistance which is optimally
suited to 5V drive circuits.
