"This unique design utilizes an automatically engaging resistor that eliminates the nuisance of using separate terminators. In addition to saving money, these adapters ensure that critical lines are properly terminated when an attached cable is removed. Choose either 50 or 75 ohm impedance."
Automatic termination of an 50 Ohm line when not coupled
Bulkhead design for panel mounting
Nickel plated body for enhanced corrosion resistance
Gold plated center contact for reduced signal loss
Eliminates accidental creation of open lines after decoupling
