Hot Bridge Wire | HBW
Hot Bridge Wire devices (HBW) are used to provide high reliable critical functions across many industries. An HBW converts electrical energy into chemical energy providing a gas or heat output. An electrical input is applied to the HBW, heating a small wire, called a bridge wire, which is in contact with the pyrotechnic. The wire quickly heats to the auto-ignition temperature of the pyrotechnic or explosive material. The pyrotechnic material then reacts providing gas pressure and/or flame. The heat and flame can be used to ignite other explosives or propellants while the gas pressure can be used to perform work.
Frequently used names are: initiator, igniter, ignitor, detonator, squib, cartridge, or pressure cartridge.
