Installed cord grips make for easy sensor hookup
Small BNC termination boxes offer a simple, economical and safe method for accessing up to four sensors that
are installed in remote locations. Each features a wall mountable, fiberglass, NEMA 4X (IP65) enclosure, an
internal terminal strip for connection to pigtailed sensor cables and externally mounted BNC jack connectors
for interface to data collection equipment. BNC termination boxes do not supply sensor excitation power.
Simply connect a data collector, with sensor excitation power, to the BNC jack of the sensor channel of
interest to access that sensor‘s measurement signal.

Enclosures
BNC termination enclosures offer a simple, economical and safe
method for accessing up to 12 sensors that are installed in remote
locations. Each features a wall mountable, fiberglass NEMA 4X
(IP66) enclosure, an internal terminal strip for connection to pigtailed
sensor cables and internally mounted BNC jack connectors for
interface to data collection equipment. BNC termination enclosures
do not supply sensor excitation power turn on.Simply open the
enclosure door and connect a data collector, with sensor excitation
power turned on, to the BNC jack of the sensor channel of interest
to access that sensor‘s measurement signal.

Switch Boxes
Enclosures
n
Enclosures provide a convenient, centralized data collection point
n
Improve efficiency with temperature & vibration outputs in one enclosure
n
Help extend cable life by reducing the number of connections needed
Switch boxes assist with route-based data collection by terminating the cables of permanently installed
sensors at convenient, safe, data collection locations.
The unit does not contain a power supply rather it relies on transferring excitation power provided by the
vibration data collector or signal conditioner to connected sensors. Since excitation power is presented to
each sensor when its measurement channel is selected, the sensor’s settling time must be considered prior to
taking measurements. Models 691B41 and 691B42 are available with a variety of cord grip options. When cord
grips are ordered, the enclosure will be provided with holes drilled for the appropriate cord grips.
