The OMEGAROMETER™ Series
accelerometers are designed for
industrial vibration measurements.
They feature a hermetically sealed
316L SS case suitable for harsh
environments. The ACC787A is a
general purpose model with a side
cable exit.

Amphenol 97-3106A-10SL-4S type
Recommended Cabling: ACC-CB7-10
NOTES:1To minimize signal distortion when
driving long cables or high-vibration signals,
24 to 30 Vdc powering is recommended. The
higher-level constant current source should
be used when driving long cables.

A maximum current of 6 mA is
recommended for operating temperatures
above 100 °C (212°F).
