PERSONAL INJURY
• DO NOT USE these products as safety or
emergency stop devices, or in any other
application where failure of the product could
result in personal injury.
Failure to comply with these instructions could
result in death or serious injury.
GENERAL INFORMATION
40PC Series miniature pressure sensors are fully
compensated and amplified. The 0.5 to 4.5 V analog
output voltage signal is linearly proportional to input
pressure.
The miniature 6-pin DIP package mounts easily
on printed circuit boards. Pin 1 is clearly indicated
by the square corner. The 3 pins opposite the 3
active pins are inactive and may be clipped off if
desired.
SOLDERING/ASSEMBLY
Limit soldering to 315°C (600°F) maximum for 10
seconds maximum. Leads must be adequately
supported during any forming/shearing operation to
ensure that the leads are not stressed inside the
plastic case.
Clean appropriately in accordance with applicable
safety procedures
