BITE Indicators
Self-Restoring Type
Model BIS
|
 |
|
Our
BIS series indicators provide visual indication of the
status of any circuit parameter being monitored. This
series is a self-restoring design that automatically
returns to a neutral state when power is removed.
Covered by U.S. and Foreign Patents.
Cleared by DOD/OFOISR for
public release under 00-S-1235 dated April 17, 2000.

OPERATION
When the indicator coil is energized, the highly visible
two color display ball changes color by spinning 180°.
It does not latch to the core magnet, but remains suspended
in that position until power is removed.
The BIS indicator offers excellent visibility
in high ambient light and does not contain any bearings,
springs, or filaments that can wear out.
Optional features include insulated lead
wire termination, special lenses (radius dome, cylindrical,
non-glare), O-Ring panel seal, and RFI panel shield.
Consult the factory for details.
Care should be taken in the application
of this device. As a magnetic component, it is subject
to magnetic interference from other devices which may
emit magnetic fields. Consult the factory if any possibility
of interaction exists.

When
ordering, show model number first, then coil voltage
desired, then the color combination desired. If this
is a special part, factory modification number will
be added at the end of the
ordering number.
Example:
A
basic model with a front panel threaded case for 12
volts with black as an unenergized color and white as
an energized color would be Model BIS21T12-W/BLK.
