Wilcoxon Sensing Technologies 731 Series Compact Seismic Accelerometer

The Wilcoxon Sensing Technologies 731 series compact seismic accelerometer is designed for long-term, reliable use. It is constructed with 316L stainless steel. The 731-207 features a 10-32 UNF tapped hole for mounting with SF1 stud (included) and a 10-32 coaxial output connector.

The 731A and 731A/P31 system feature a 2-pin, MIL-C-5015 output connector and include a SF7 mounting stud. Both accelerometer styles are hermetically sealed and manufactured in an ISO 9001 facility.
