Models BHG (Single Coil) and BHGD (Dual Coil) For indicators qualified to MIL-PRF-83287/3, see page 29. BALL INDICATORS Our latching feature assures fast positive response to a fault signal. The display ball changes color only when the indicator coil is pulsed by a BITE (Built-In Test Equipment) system. Our magnetic indicators have no bearings, springs or filaments to wear out and offer excellent visibility in high ambient light. FEATURES • Magnetic latching • Small, lightweight • High visibility • Ruggedized OPERATION When the indicator coil is energized with a 40 millisecond (or longer) pulse,...

MINIATURE BITE INDICATORS ORDERING INFORMATION When ordering, show model number first, coil voltage and the color combination desired. If this is a special part, a factory assigned modification number will be added at the end of the ordering number. Consult the factory for special configurations. Standard factory options are designated by “-Sxxx” Basic Model Number Example: Single coil model with front panel threaded case for 12 volts with white as set color and black as reset color would be Model BHG21T-12-W/BLK. No-fault or Reset Color BHG……TL = Domed lens * MIL qualified indicators Set/Reset...

BALL INDICATORS Model BIS Our BIS series indicators provide visual indication of the status of any circuit parameter being monitored. This series is a selfrestoring design that automatically returns to a neutral state when power is removed. FEATURES • Self-restoring • Sunlight readable • Small, lightweight • Ruggedized 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...

FLAG INDICATORS Model MI51LP The MI51LP is a miniature, dual-drum, magnetic latching indicator featuring a nonvolatile two-drum display, excellent positive indication of a fault condition with superior visibility in high ambient light. It is designed to monitor electronic systems where space is limited. FEATURES • 50 milliwatt • Magnetic latching • Manual reset • Environmentally sealed OPERATION When the indicator coil is energized with a 25 millisecond (or longer) pulse, the highly visible drums spin 180° and latches to the magnetic core. The drums will remain magnetically latched to the core...

LOW POWER BITE INDICATORS ORDERING INFORMATION When ordering, show model number first, coil voltage, the color combination desired, terminal type, and glass type. If this is a special part, a factory assigned modification number will be added at the end of the ordering number. Consult the factory for special configurations. Standard factory options are designated by “-Sxxx” Basic Model Number Coil Voltage Fault Color No-fault or Reset Color Terminal Type Glass Type Example: Basic model for 12 volts with white as set color and black as reset color, turret terminals, and non-glare glass would be...

FLAG INDICATORS BITE INDICATORS Model MI57DA For Indicators qualified to MIL-PRF-83287/2, see page 28. The MI57DA magnetic latching fault indicator displays a highly visible dual color internal flag when the indicator coil is pulsed by a BITE (Built-in Test Equipment) system. The “cloverleaf” pattern provides a high-contrast, visual identification and an effective warning of system results. FEATURES • Electrical reset • Environmentally sealed • Magnetic latching • Rear mount • Positive identification OPERATION When the indicator coil is energized with a 40 millisecond (or longer) pulse, the highly...
