Miniature BITE Indicators
Self-Restoring Type
Model BIS

Print information as a condensed 2 page document

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.

ORDERING INFORMATION

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.
