(1) 6-32 tapped hole in non-tubulated end.
(2) Identical tubulation on both ends.
(3) The voltage level at which the spark discharge occurs when a unipolarity pulse train is applied to the gap. Typically, the pulse repetition rate is 400 pps (pulses/second) with a rise
time of 0.3 µs and a pulse width of 0.5 µs. The “initial” range specifies at what increasing voltage the gap begins to fire and the “rep” range specifies at what decreasing voltage the
gap ceases to fire repetitively.
(4) Pulse repetition rate is 1500pps instead of the standard 400pps.
(5) Though outlines 2, 3, and 3A are identical, the electrode materials and configurations vary internally.
(6) Though outlines 4 and 4A are identical, gaps with outline 4A have heavier internal construction to withstand more severe shock and vibration.
